Abstract: Critique ability, i.e., the capability of Large Language Models (LLMs) to identify and rectify flaws in responses, is crucial for their applications in self-improvement and scalable oversight. While numerous studies have been proposed to evaluate critique ability of LLMs, their comprehensiveness and reliability are still limited. To overcome this problem, we introduce CriticEval, a novel benchmark designed to comprehensively and reliably evaluate critique ability of LLMs. Specifically, to ensure the comprehensiveness, CriticEval evaluates critique ability from four dimensions across nine diverse task scenarios. It evaluates both scalar-valued and textual critiques, targeting responses of varying quality. To ensure the reliability, a large number of critiques are annotated to serve as references, enabling GPT-4 to evaluate textual critiques reliably. Extensive evaluations of open-source and closed-source LLMs first validate the reliability of evaluation in CriticEval. Then, experimental results demonstrate the promising potential of open-source LLMs, the effectiveness of critique datasets and several intriguing relationships between the critique ability and some critical factors, including task types, response qualities and critique dimensions.

Main paper: 
 introduction: 
 Critique ability is crucial for the self-improvement [1, 2] of LLMs, as it enables the effective analysis and correction of flaws in responses [3, 4] . This capability also facilitates a more robust framework, i.e., scalable oversight [5, 6] , for ensuring the AI systems growing in scale and capability remain aligned with human-desired outcomes and ethical standards.So far, while numerous works have been proposed to evaluate critique ability of LLMs in downstream tasks, like common NLP tasks [7, 8] and reasoning tasks [4, 9] , their comprehensiveness and reliability are limited. Specifically, existing works [10, 11, 12] typically evaluate only specific aspects of critique ability, resulting in limited evaluated critique dimensions [13, 11, 12, 10, 14] , insufficient analysis of response qualities and task types [4, 9] . Besides, while GPT-4 is frequently used to evaluate textual or natural language critiques [3, 10, 13] , its reliability across all critique dimensions and tasks remains unverified [10, 15] . In summary, a comprehensive and reliable benchmark for assessing critique capability of LLMs is still under-explored, significantly impeding the in-depth analysis.Table 1 : Comparison between the test and dev set of benchmarks and CRITICEVAL. A complete list are described in Appendix C. The response quality in some benchmarks is unclassified (-). PR denotes the Pass Rate on reasoning and coding tasks. Our concurrent works are marked with a †.Extensive evaluations of 35 widely used open-source and closed-source LLMs prove the reliability of CRITICEVAL. Specifically, GPT-4 with human-annotated reference critiques achieves close correlations with human judgments, while removing them results in significant performance loss. Additionally, critiques with higher scores consistently lead to superior improvements, illustrating a clear correlation between the real critique ability of LLMs and their evaluation scores within CRITICEVAL. Then, extensive evaluations results also demonstrate that some open-source LLMs, such as Qwen [21] and InternLM2 [22] , are approaching state-of-the-art closed-source LLMs in critique capabilities, and their critique ability could be further improved through scaling strategy. Besides, the effectiveness of critique datasets is also validated. Finally, these evaluation results also reveal several intriguing phenomena:• Critique difficulty varies by task type. For instance, math reasoning and coding tasks are more challenging for feedback, comparison, while they are easier for meta-feedback.• There is an inverse relationship between the quality of critiques and responses. For example, high-quality responses pose a greater challenge to critique effectively.• Critique difficulty correlates with the critique dimensions; notably, comparison and metafeedback dimensions present greater challenges than feedback dimension.These observations and phenomena promote an in-depth understanding of critique ability of LLMs. We hope the discoveries could spur future research in this field. 
benchmarking critique ability: 
 So far, numerous meta-evaluation benchmarks have been proposed to evaluate the critique ability of models [18] . Early benchmarks mainly focus on evaluating scalar-valued critiques [30, 24] on common NLP tasks [18, 23] , like translation [7] and summary [8] by computing the correlations between model and human judgments. Recent works also assess scalar-valued critiques of LLMs on reasoning and coding tasks [24, 9] . For example, CRITICBENCH [9] built from 3 reasoning tasks, analyzes important properties of critique ability of LLMs. Our concurrent work, CRITICBENCH [4] analyzes several intriguing findings among generation, critique and correction capability on responses collect from five reasoning tasks. 3 Compared with these existing works, our proposed CRITICEVAL exhibits advantages on several crucial factors, like critique dimensions, response qualities and diverse task types, leading to more comprehensive evaluations for critique ability. Although CRITICBENCH [9] collect high-quality responses, their quality levels are still unclassified.Beyond scalar-valued critiques, evaluating textual critiques is more challenging [10, 15] . Most existing works coarsely evaluated textual critiques using GPT-4 [11, 12] , proven unreliable [10, 13] . Unlike them, our extensive results prove that GPT-4 with human-annotated critiques is reliable for evaluating textual critiques. Although our concurrent work, MetaCritique [13] , demonstrates the reliability of evaluating textual critiques by verifying their Atomic Information Units, it is unclear whether their conclusions could be extended to more critique dimensions and tasks. 
preliminaries: 
 We first formally define the key concepts and their corresponding notions in CRITICEVAL. Figure 1 shows a specific case to understand these concepts.Task Input (I) and Response (R) represent the queries and generations of LLMs, respectively.Critique aims to analyze and refine the generated responses. Formally, this paper studies the critique capabilities in four dimensions: (1) feedback F s involves textual analysis and a quality score. Good feedback should not only find flaws in responses but also provide helpful suggestions for correction [6] ; (2) correction or refinement CR aims to revise responses with or without feedback.Previous evaluations [11, 12, 9] overlook this dimension, although it is an inevitable step when letting the model improve itself [35] ; (3) comparison F c contains a textual critique and a preference label for a pair of responses (R a , R b ); (4) Meta-feedback F s (F s ), i.e., the feedback of feedback itself [6] , involves a rating score reflecting the quality of F s and corresponding textual analysis, which is a high-level critique dimension. Such an ability is necessary to improve critique ability of LLMs [1, 13] .Due to the complexity of the meta-feedback dimension, textual critiques are not collected in this paper, and we leave it for future research.Response B is more helpful than A ... On the contrary ,response A only claims it cannot solve this input . B/AB Feeback Correction Generated response fails to fulfill user's query ... Following suggestions could be considered ...Here is the revision for response A: Of course! To make a pizza,the following ingredients are needed: ...Sure,here is a recipe for pizza: ... I do not know any recipe ... To the best of our knowledge, these four critiques cover all categories of critiques examined in prior research [11, 4, 13] . Although the feedback of correction and comparison dimensions are also important, they are not essential for the self-improvement of LLMs. Thus, this study mainly focuses on studying the feedback of feedback F s (F s ) and leaving the rest of them for our future work.The response is difficult to read and understand due to the repetitive listing of ingredients. It's also missing instructions on how to prepare the dish. 
criticeval construction: 
 Given the challenge of crafting scalar-valued and textual critiques from scratch, we construct CRIT-ICEVAL using a human-in-the-loop data construction pipeline as shown in Figure 2 . 4Task inputs for 9 distinct tasks are collected to evaluate critique capabilities comprehensively (Step 1 in Figure 2 ). Specifically, CRITICEVAL includes three widely used tasks for evaluating critique ability:(1) representative classical language tasks: summary [39] , translation [40] , and question-answering [41] ; (2) LLM alignment: general chat scenarios [19] and harmlessness cases [35] ; (3) reasoning and code capabilities: math reasoning with chain-of-thought (CoT) and program-of-thought (PoT), and coding with and without execution results. We hereinafter refer to "code w/ execution" as "CodeExec" and "code w/o execution" as "CodeNE". For each task, we collect around 100 task inputs from the test sets of some widely used benchmark datasets to ensure the task input quality and avoid data contamination. Please refer to Appendix D for more details about the data source.For each collected I in each task, LLMs of different scales and capabilities are first employed to generate responses with diverse flaws (Step 2 (a) in Figure 2 ). The complete list of LLMs is in Appendix E. Then, low-, medium-, and high-quality responses with diverse quality differences are collected according to the quality score annotated by the human raters with GPT-4-turbo as the assistant ( Step 2 (b)). Moreover, we also collect golden or correct responses, which have been proven challenging for critiques [15] . More details about how to select low-, medium, high-quality and correct responses can be found in Appendix F.After collecting responses, we further collect critiques to be evaluated for the meta-feedback dimension by utilizing four LLMs that are known powerful for critiques (Step 3 (d) in Figure 2 ): (1) GPT-4;(2) GPT-3.5-turbo; (3) Auto-J-13B [11] ; (4) UltraCM-13B [12] .After collecting task inputs and responses, four kinds of reference critiques are collected on these responses to make the objective and subjective evaluation in our proposed CRITICEVAL more reliable. Feedback and Correction GPT-4-turbo is utilized to generate feedback and corrections sequentially (Step 3 (c) and (e) in Figure 2 ). The scalar-valued and textual critiques for feedback dimension StepStep are collected, denotes as "score" and "text" in Figure 2 . Since responses in math reasoning and coding tasks pose significant challenges for critiques during our annotation, ground-truth answers are provided for GPT-4 as references to generate high-quality feedback and corrections. Then, they are carefully reviewed and revised by human annotators.Comparison Our empirical finding suggests that pairs of responses pose greater challenges for comparison if they perform similarly. Therefore, two kinds of pairs are first created: (R low , R high ) and (R med , R high ), designated as the easy and hard samples, respectively. Then, GPT-4-turbo is prompted to provide scalar-valued and text critiques on these pairs (Step 3 (f) in Figure 2 ). These outputs, labeled as "preferred label" and "text" in Figure 2 , are then refined by human annotators. Meta-Feedback Since GPT-4 has been proven unreliable to evaluate critiques [10, 15] , three human experts are asked to provide their quality scores for generated critiques (Step 3 (d) in Figure 2 ).During human annotation, multiple human experts are asked to follow a rigorous annotation protocol, detailed in Appendix H.1, and the statistics of human annotation for reference critiques are described in Appendix H.6. Besides, several case studies are shown in Appendix I to facilitate a clear understanding of our proposed CRITICEVAL.5 Evaluation MetricsThe response contains repetition of ingredients, specifically dried apricots and dried figs, which are listed multiple times. This is not logical in a recipe context. To improve the response, the model should provide an accurate recipe for Koldskål, including the correct ingredients and preparation instructions. The model should also avoid repetition of ingredients and ensure the response is clear and easy to understand. # Generated Feedback The recipe for Koldskål is not provided. 
objective evaluation: 
 Feedback and meta-feedback evaluation aim to evaluate the consistency between generated scores and human judgments. This setup facilitates the generation in a chain-of-thought manner, followed by the quality score of the evaluated critiques. For the meta-feedback dimension, LLMs are prompted with annotated reference critiques. The widely-used Spearman correlations [42] are computed [23, 24] , which ranges from -1 to 1 (normalize to (-100, 100)). Higher scores indicate a higher consistency with human judgments. The p-value of spearman correlation are recorded, and p < 0.05 is typically considered to be statistically significant [23, 43] .Comparison evaluation assesses the accuracy of LLM in deciding preferences between two responses. It is well known that current LLMs exhibit significant positional bias [17, 44, 45] , i.e., LLMs tend to prefer responses based on their specific position in the prompt. We implement a rigorous verification process to mitigate the effects of positional bias. Specifically, given responses R a and R b to be compared, we obtain the comparison based on two orders, noted as Correction evaluation is only conducted on math reasoning and coding tasks since the revision could be easily verified with the ground-truth answers and the test cases [4, 9] . Thus, the objective evaluation metric is implemented as the pass rate: NPass N , where N and N Pass are the number of the total samples and passed samples, respectively.F a c = F c (R a , R b )The subjective evaluation aims to evaluate the quality of the generated textual critiques. Since responses in math reasoning and coding tasks can be verified, we only conduct subjective evaluations on other 5 tasks for the correction dimension. In our work, GPT-4 evaluates the generated critiques by generating the chain of thought followed by the score, with our human-annotated critiques as references. It is well-known that LLMs prefer longer generations during their automatic evaluation [46, 45] . However, Figure 7 in Appendix J proves that there is no clue that GPT-4, with our concise and precise reference critiques as input, would give higher scores to longer critiques. The subjective scores range from 1 to 10. Following previous work [20] , the human-annotated reference critiques are anchored to 8, serving as a relative scoring pivot.The overall score of subjective and objective evaluation is computed as averaging on all the critique dimensions, and more details about computing the overall score can be found in Appendix K. 
evaluation and analysis: 
 The critique abilities of representative LLMs are analyzed in this section, and the overview results are shown in Table 2 . Firstly, the reliability of evaluation in CRITICEVAL are proven in Section 6.2 and Section 6.3. Then, overall analysis is described in Section 6.4. Furthermore, several intriguing phenomena about some critical factors are described, including task types (Section 6.5), the response quality (Section 6.6) and the critique dimensions (Section 6.7). Finally, we elaborate and analyze the fine-grained error patterns of model-generated critiques in Section 6.8. The complete experimental results of all evaluated LLMs on the test/dev set for each task and each critique dimension are placed in Appendix L.35 widely used open-source and closed-source LLMs of different sizes are evaluated on CRITICEVAL, including the instruction-tuned LLMs [21, 50, 22, 51] , critique-tuned LLMs that fine-tuned on critique datasets generated by 12, 30] , and reward models [12, 52, 53] . Please refer to Appendix N for all evaluated LLMs and the inference details. The prompt templates for LLMs on critique dimensions are shown in Appendix I with score rubrics listed in Figure 18 in Appendix H.3. As LLMs are prompted with human-annotated critiques, their performance in meta-feedback could reveal their reliability for evaluating generated textual critiques. As shown in Table 2 (F s (F s ) column) and Table 3 , GPT-4-turbo achieves very high correlations (62.90, and 66.18) with human judgment. Although there is still a gap compared to the average human level (66.18 < 79.03), the strong correlations ensure the reliable evaluation for textual critique ability [23] . Furthermore, we also conduct the ablation study to prove the contribution of our human-annotated reference critiques. As shown in Table 3 , it can be found that all LLMs perform worse when the reference critiques (ref.) are removed (average -13.36 performance decrease), proving their significant contribution for reliable subjective evaluation in our proposed CRITICEVAL. Moreover, except for the feedback critique dimension, we also test the reliability of subjective evaluation on the correction and comparison critique dimensions. Specifically, we ask three human annotators to annotate the quality score of 450 critiques generated by five representative LLMs (GPT-3.5-turbo, Qwen-72B-Chat, InternLM2-20B-Chat, Mistral-7B and ChatGLM3-6B) from 9 tasks in CRITICEVAL, and all the human annotators are guided by the same evaluation protocol in our subjective evaluation. The results are shown in Table 4 . It can be found that GPT-4-turbo, with our human-annotated critiques as references, could achieve a very strong correlation with human judgments, close to the average human level. This observation proves the robust and reliable subjective evaluation of the textual critiques in the correction and comparison dimensions. Besides, the correlation scores on the correction and comparison critique dimension are higher than the feedback dimension. This phenomenon suggests that the feedback of the feedback is more challenging than the feedback of correction and comparison. Although the reliability of subjective evaluation has been proven in Section 6.2, it is still unknown whether real feedback critique ability of LLMs is consistent with the evaluation results in CRITICEVAL. To explore this, we prompt the InternLM2-20B-Chat and Llama2-70B-Chat models to revise responses from CRITICEVAL using three sources of feedback with varying quality levels. As illustrated in Table 5 , a clear and consistent trend emerges: as the quality of the feedback increases, both the objective and subjective revision performance improves. This finding underscores that real critique ability of LLMs aligns closely with the evaluation results in our proposed CRITICEVAL, i.e., critiques of LLMs with higher scores are more accurate and effective for corrections.In summary, the reliability of evaluation in CRITICEVAL has been well proven. Following sections will describe the overall analysis and relationships between critique ability and several crucial factors. As shown in Table 2 , GPT-4 significantly outperforms other LLMs on most critique dimensions, while slightly underperforms our human-annotated critiques (7.81 < 8) . Surprisingly, open-source LLMs are approaching state-of-the-art closed-source LLMs. For example, InternLM2-20B-Chat surpasses GPT-3.5-turbo on overall subjective scores (6.20 > 5.89). Furthermore, there is a clear relationship that the critique ability of LLMs improves steadily as the number of parameters increases (Table 2 ), suggesting that the critique ability of LLMs highly correlates with their capability. We also provide a clear diagram to show this relationship in Figure 14 in Appendix R. Beyond the average scores, we also categorize the textual critiques of LLMs into multiple quality intervals for more interpretable analysis, which are described in Appendix O. The results of critique-tuned LLMs in the feedback dimension on the test set are shown in Table 6 . It can be found that critiquetuned LLMs fine-tuned from Llama-2-13B significantly outperform even the Llama-2-70B-Chat model, proving the effectiveness of critiques datasets [11, 12] . The results of representative reward models are shown in Table 7 . From these results, it can be found that reward models like UltraRM-13B achieve impressive performance in scoring the quality of responses, significantly outperforming GPT-3.5-turbo. This observation aligns with findings in recent works [14] . Effective critiques usually require domain knowledge and understanding of given tasks. We analyze the relationship between critique ability and task type in Table 8 , which shows the average performance of all evaluated LLMs. Feedback, Comparison LLMs achieve much higher scores in the first five tasks than on math reasoning and coding tasks, indicating math reasoning and code tasks are more challenging. Meta-Feedback LLMs achieve much higher consistency with human judgments on code and math reasoning tasks, indicating that evaluating textual critiques in math reasoning and code tasks is more reliable. Correction Math reasoning tasks are more challenging than coding tasks, and CodeExec is easier to revise than CodeNE due to the richer information in execution results. Except for math reasoning and coding tasks, the translation is the most challenging task because professional domain knowledge is required, while harmlessness is the easiest to refine since most LLMs have been trained to avoid harmful generations [35] . Furthermore, we explore the variance in correction quality on reasoning and coding tasks (Obj. in Table 9 ) and other subjective tasks (Sub. in Table 9 ). 5 Specifically, three kinds of feedback are used for correction: (1) Human-annotated Feedback (HF); (2) Empty Feedback (EF), where LLMs are prompted to improve responses without any feedback; and (3) LLMs Self-generated Feedback (SF). As shown in Table 9 , it can be found that self-generated feedback is beneficial to corrections on subjective evaluation (HF(7.12) > SF(5.48) > EF(5.16)), while it might negatively affect corrections on objective evaluation of math reasoning and coding tasks (SF(13.01) < EF(14.44) < HF (43.66) ). This observation proves that LLMs struggle in self-improvement on challenging reasoning tasks, aligning with recent findings [54, 4] . Given the distribution of error patterns, we analyze critique ability of LLMs on responses with varying qualities. As shown in Table 11 , highquality responses are the hardest for feedback since they contain lots of subtle errors (Table 10 ). Note that the medium-quality responses have higher objective feedback scores than lowquality ones, which is inconsistent with our expectations. This phenomenon is because lowquality responses often receive very low human-annotated quality scores (near 1), while the scoring of LLMs tends to be higher, leading to a discrepancy. For the correction dimension, low-, and high-quality responses are easier to correct than medium-quality due to the most obvious and subtle errors. There are two kinds of qualities for comparison dimension: easy and hard. Most LLMs perform better on easy samples than on hard samples. Specifically, the subjective and objective scores of easy samples are 4.78 and 39.73, respectively, higher than those of hard samples (4.55 and 29.80).For the meta-feedback dimension, LLMs achieve the highest consistency with human judgments on high-quality responses while performing worst on medium-quality responses. The average scores of all evaluated LLMs on different critique dimensions are shown in Table 12 . Objective scores of comparison and correction are not recorded because they are not correlations. Several conclusions can be made: (1) correction is the easiest critique dimension, followed by feedback, and then comparison. This observation demonstrates that comparison requires accurate analysis of both responses, which is more complex than the feedback dimension; (2) As a high-level critique dimension, meta-feedback is more challenging than the feedback.This section analyzes the fine-grained failure modes in model-generated critiques across feedback, comparison and correction dimensions. As illustrated in Table 13 , human annotators summarize the 12 main failure modes in model-generated critiques. Then, we compute the distribution of these failure modes of all evaluated LLMs. Figure 3 demonstrate that the most frequent failure modes are missing errors (E1, E2), lacing effective comparison analysis (E7) and worse revision than references (E10) for feedback, comparison and correction dimensions, respectively. Furthermore, as shown in Figure 4 , it can be observed that missing errors/suggestions (E1, E2) and inaccurate critiques (E3, E4, E8) usually lead to lower subjective scores. Feedback misses some errors.Feedback misses revision suggestions or suggestions are low-quality.Feedback incorrectly analyzes correct content as erroneous.Feedback content contains errors.Feedback is correct but complex.Feedback is not concise, repetitive or irrelevant.Critiques lack effective analysis between two responses.Preference between two responses is wrong.Revision does not follow suggestions in feedback well.Revisions are better but have not reached the reference.There are some errors in revisions.  
conclusion and future work: 
 In this paper, we introduce a comprehensive and reliable benchmark for evaluating the critique abilities of LLMs, named CRITICEVAL. Extensive experimental results first prove the reliability of CRITICEVAL, and reveal the promising potential of open-source LLMs, the effectiveness of critique datasets and intriguing relationships between critique capabilities and some factors: task types, response qualities and critique dimensions. These observations significantly promote an in-depth understanding of the critical ability of LLMs and LLM's self-improvement. In the future, we plan to enhance our benchmark in several key areas: (1) Broadening the scope to include more tasks, such as tool-using; (2) Extending the benchmark to encompass other languages, like Chinese; (3) Improving the subjective evaluation protocol to allow for more fine-grained analysis; (2) Continue to evaluate LLMs and track their critique ability, like Llama-3 models; (5) Improving the quality of reference critiques by incorporating additional high-quality critiques from advanced LLMs if and only if their quality surpasses the existing reference critiques.

 Appendix: A.1 Sub-optimal Reference Critiques Following previous work [20] , our work construct CRITICEVAL with the human-in-the-loop annotation pipeline, i.e., multiple human annotators are asked to review and revise the critiques generated by GPT-4 model. Even though we have established a rigorous annotation process to ensure the high quality of annotated critiques, human annotators are inevitably influenced by GPT-4's initial generated critiques in some more open-ended tasks, like general chat and QA tasks. This problem may result in the quality of revised critiques by human annotation still being sub-optimal. To address this problem, we plan to enhance CRITICEVAL in our next version. Specifically, we will replace existing reference critiques with potential better critiques generated by advanced evaluated LLMs, like Claude-3 6 , if and only if their qualities surpasses reference critiques.CRITICEVAL mainly utilizes the advanced GPT-4-turbo model for subjective evaluation. Despite integrating high-quality annotated reference critiques to guide GPT-4 toward more accurate assessments, it's essential to acknowledge that the model's evaluations may not always align perfectly with human judgment. While GPT-4 have yet to reach the level of precision of human annotation -they currently represent the most effective approach for balancing the trade-offs between evaluation cost and quality. It is still a significant challenge to accurately and automatically evaluate critiques across all scenarios. Recognizing this, we aim to address these issues in our future work by progressively refining our benchmark and evaluation protocols.Compared with existing benchmarks [12, 10, 14, 13] , our proposed CRITICEVAL exhibits significant advantages in the diversity of evaluated task scenarios. Although we strive to cover a wide range of diverse generation tasks, there are still some tasks have yet to be considered, such as tool learning [55] , knowledge-intensive tasks [56] and hallucination [57] . In our future work, we will continue to include more tasks in the next version of CRITICEVAL.A.4 More LLMs to be Evaluated Some newly proposed LLMs and reward models [58] have not been added yet, like Llama-3 7 and Claude-3 series models. Since our conclusions are summarized from evaluation results of over 35 open-source and closed-source LLMs, lacking these LLMs does not affect conclusions. We will continue to evaluate their critique ability in our future work.In this paper, all the evaluated models generate the critiques by using the greedy-search decoding method. There exist some inference strategies to potentially improve the model's performance, like structured generation [59] . The primary goal of our proposed CRITICEVAL in the current stage is to construct a comprehensive and reliable benchmark for evaluating the critique ability of LLMs, and we will explore these inference strategies to improve the critique ability in our future work.Most task inputs in CRITICEVAL are collected from publicly available datasets, free from any possible harm toward individuals or groups. Moreover, humans carefully select and process the responses and critiques generated by LLMs to secure privacy and confidentiality. No personal identification information is involved. However, it should be noted that the task input, responses, and critiques in the Anthropic-HHH dataset [60] of the harmlessness task contain harmful materials and hate speech. Despite the risks involved, it is essential to disclose this research fully, and materials in the Anthropic-HHH dataset have been widely used for safety research in the LLM community. All raters have been paid adequate wages. The hourly wage of our human annotators is about 5.69 USD, which is much higher than average hourly wage 3.13 USD on Amazon Mechanical Turk [61] .The comparison between CRITICEVAL and existing benchmarks can be found in Table 14 , which proves the advantages of our proposed CRITICEVAL for critique evaluation. Compared with existing benchmarks for critique evaluation, our proposed CRITICEVAL contains 3, 608 textual natural language critique samples (textual critiques) that are well annotated by multiple human annotators, leading to a more stable and reliable assessment in our subjective evaluation. The scale of objective evaluation data (scalar data) in our dataset is second only to Chat Arena8 and SummEval [8] . However, compared to these two datasets, our dataset contains a more diverse range of critique dimensions and tasks (nine diverse tasks). Moreover, the statistics of CRITICEVAL in the test and dev set are shown in Table 15 .Table 14 : Statistics of existing critique benchmarks, meta-evaluation benchmarks (scalar-valued critique evaluation), and CRITICEVAL. NL and Scalar denote natural language feedback and scalarvalued feedback, i.e., the preference label or Likert score [3] . CriticBench [9, 16] contain two kinds of response quality (correct and wrong). The responses in some benchmarks are not unclassified, and we set them as unclassified (-). Scalar-valued critiques in Auto-J [11] are from its Eval-P, and textual critiques are from Eval-C split. The benchmark includes three representative classical language tasks: summary [39] , translation [40] , and question-answering [41] . Since a popular application of LLMs is to serve as a chatbot, where alignment is important to ensure the safe application of LLMs, we collect instructions from general chat scenarios [19] and harmlessness cases [35] to evaluate the LLMs' critique ability for alignment. Furthermore, the reasoning and code capabilities are also fundamental for augmenting LLMs as agents [78] , another important and promising application of LLMs. Thus, we also collect To ensure the difficulty of CRITICE-VAL, we only collect coding and math reasoning questions that some 70B LLMs cannot correctly answer, which is proven effective in previous works [9] . Our motivation is to collect questions that could easily raise responses with diverse flaws. Simple questions pose challenges for us in achieving this goal since most LLMs can easily solve them. Collecting these questions that 70B LLMs cannot answer correctly makes the difficulty of questions become moderate or complex, which aligns with our motivation.The details of selected datasets for 9 tasks are listed in Table 16 , covering the well-known NLP tasks (translation, summary, and question answering), reasoning tasks (mathematics and coding), and alignment (general chat and harmlessness). These datasets' test sets are used for CRITICEVAL construction, avoiding data contamination. For each task, we collect around 100 instructions from the test sets of some widely-used benchmark datasets to ensure the instruction quality and avoid data contamination.Our dataset is under Apache 2.0 License.Our study uses several LLMs with different capabilities to generate diverse feedback, listed in Table 17 . Besides, we also use some critique-tuned LLMs to generate textual feedback, like Auto-J-13B and UltraCM-13B models. To identify the quality of these responses efficiently, GPT-4 is utilized to initially assign quality ratings ranging from 1 to 7 (Step 2 (b) in Figure 2 ) then let human annotators meticulously review and adjust these scores, which are used in the objective evaluation in the feedback dimension (Section 5.1). then, three responses with distinct quality differences for each I are sampled based on their human-verified quality scores, including low-, medium-, and high-quality responses (noted as R low , R med , R high , respectively). Due to partial simple or hard queries, there might be queries where the scores of The statistical of responses' quality scores on 9 tasks can be found in the Figure 5 . Figure 5 demonstrates the discernible performance disparities in responses for each task. Since automatic execution leaks quality information, we do not collect the correct responses for the Code-Exec task. Such variation is instrumental in analyzing the impact of response quality on the feedback.Golden or correct responses are collected for each task input I, which are proven challenging for critiques [10, 15] . We use GPT-4 to generate correct responses using ground-truth rationales or codes as hints for coding and mathematical tasks. Since executions leak information about response quality, correct responses are not collected for the CodeExec task. In tasks beyond coding and mathematics, GPT-4 is prompted to refine its past generations, given its feedback during multiple turns, and the last revision is collected as golden response.We construct the high-quality reference critiques by using human-in-the-loop data generation pipeline, which is motivated by two essential considerations (effectiveness and efficiency).Human-written Critiques are Usually Insufficient -Sub-optimal (Effectiveness) Our trial human annotation reveals that human annotators might neglect some apparent or severe issues when writing critiques from scratch, consistent with findings in recent studies from OpenAI [79, 6] . Our experimental result in Appendix M demonstrate that neglecting issues usually leads to low-quality critiques. In contrast, despite the possibility of generating wrong critiques, LLMs like GPT-4 offer more comprehensive and detailed critiques [79] . By revising LLM's errors by human experts, the final critiques could be more comprehensive and accurate, leveraging the strengths of both human annotators and LLMs.Annotating Challenging Critique Task from Scratch Cost A Lot (Efficiency) Writting critiques from scratch is a significant challenge [20, 10] . For instance, Shepherd [52] incurred an annotation cost of 8$ per sample, leading to over 28,864$ and 1,350 work hours to annotate the entire CRIT-ICEVAL, which is unbearable for our project. Thus, we have to employ advanced LLMs to generate draft critiques, followed by human annotation. GPT-4 was chosen because our preliminary studies indicate that it is the most reliable LLM for producing draft critiques, while other LLMs are much worse. Consequently, a diverse set of LLMs introduces more noise in generated critiques, bringing more difficulties to human annotators.In conclusion, the human-in-the-loop pipeline achieves the trade-off between annotation cost and quality. We promise to add these details to the revised paper to emphasize the motivation of using the human-in-the-loop pipeline.Three to five human annotators annotate each scalar-valued critique in each task. Biases among human annotators may arise from factors such as the annotator's gender and professional background.To minimize the impact of annotators' biases on the quality of our human annotations, we first selected a diverse group of annotators from a crowd-sourcing platform to annotate each critique sample collaboratively. All human annotators have been paid adequate wages. The hourly wage of our human annotators is about 5.69 USD, which is much higher than average hourly wage 3.13 USD on Amazon Mechanical Turk [61] .Before annotation, we designed a rigorous data annotation verification process to iteratively train these annotators, thereby ensuring the stability and reliability of the annotation quality. During annotation, these human annotators first annotate each textual critique, which are summarized by another supervisor annotator. After annotation, the supervisors (authors in our paper) conducted a 5% sample inspection. If the error rate exceeds the threshold, annotators are asked to revise their work until the error rate is lower than the threshold.It should be noted that some underlying datasets contain inaccuracies that may lead to compounding effects during evaluation. For example, we have noticed some incorrect solutions and rationales for mathematics and coding questions during our human evaluation process. In our work, to mitigate the effects of such errors, human annotators are asked to meticulously examine each question, the provided golden answers (only for mathematics and coding tasks) and the evaluated responses and critiques. They are asked to exclude instances where the golden answers or questions are flawed or incorrect, like wrong solutions to mathematics and coding questions.The annotators are entrusted with the detailed score rubrics to evaluate the different dimensions [14] .Table 18 lists the score rubrics designed for different tasks. Note that math and code tasks only need to check the correctness.Task inputs in the QA and chat tasks often require specific factual knowledge for responses. However, GPT-4 sometimes produces spurious knowledge or fails to effectively identify factual inaccuracies within these responses, a common issue known as hallucination [80, 57] . Consequently, we strongly urge human annotators involved in the feedback, comparison and correction annotations in QA and general chat tasks to verify factual content through internet searches. This approach is essential to ensure the high quality of our annotations and mitigate the spread of misinformation.To generate correct responses R corr. and critiques for challenging tasks, like mathematics and coding, we provide the ground-truth rationales as reference for GPT-4. Then, these generated responses and codes are meticulously evaluated by human annotators to ensure the accuracy and correctness of the generated responses. Human annotators are asked to exclude any direct references of ground-truth rationals in these generated R corr. and critiques.The average revision rates of textual critiques for the feedback, comparison, and correction critique dimensions are 25.22%, 34.83%, and 48.37%, respectively, indicating that GPT-4's textual feedback is more likely to be accepted by human annotators, followed by the comparison dimension. In contrast, GPT-4-turbo's correction might contain more flaws that need to be corrected. Moreover, the average inner correlation score among annotators is 0.79, indicating solid inner agreement.This section shows some cases in CRITICEVAL, subjective evaluation of feedback, comparison and correction critique dimensions.In this subsection, we have provided some cases about four critique dimensions: (1) feedback; (2) comparison; (3) correction; and (4) meta-feedback. From these cases, it can be found that samples in our proposed CRITICEVAL contains rich metadata. For example, the data source, quality, and used LLMs are listed.# Case of feedback and correction dimension { "question": "How do I make escargot?", "generation": "Place the snails in a container and cover with damp cloth or put in a plastic bag.

Figure 6 illustrates that, without reference feedback, GPT-4 erroneously attributed very high scores to its generated feedback. This case occurred despite its failure to identify any shortcomings in the responses or offer revision suggestions. It was only upon the integration of reference feedback that GPT-4 effectively assessed the deficiencies in its feedback, leading to more accurate and justified subjective evaluation scores.The case for feedback subjective evaluation is shown in Figure 8 . The generated response contains factual errors: "cool music from 1920 are King of the Jazz Band and In the Mood.". High-quality reference feedback points out these errors, while Qwen-72B-Chat's feedback fails to find them, leading to a low-quality score 2. Figure 9 shows the case for comparison subjective evaluation. The case for correction subjective evaluation is shown in Figure 10 .The case for the feedback dimension is shown in Figure 11 , and the case for the comparison dimension is shown in Figure 12 .# Question: I like to host guests at my home from time to time, and I am gathering recipes of different dishes and drinks to keep things interesting. I am interested in trying some Danish dishes. Can you give me a recipe for Koldskål? # Generated Response to be Evaluated: Here is a recipe for Koldskål: Ingredients: 4 Quart Jar, 3/4 cup chopped onion 1/2 cup chopped carrot 1/2 cup chopped celery 1 1/2 cups chopped cabbage 1/2 cup chopped mushrooms 1/2 cup chopped tomatoes 1/2 cup chopped zucchini 1/2 cup chopped ... (multiple dull repetitions) # Reference Feedback: The response provided is not satisfactory and contains several issues. 1. Factual Error: The recipe provided is not for Koldskål, a traditional Danish dish. Koldskål is a sweet dish typically made with buttermilk, eggs, sugar, vanilla, and lemon, often served with small biscuits called kammerjunkere. The ingredients listed in the response do not reflect this. 2. Relevance: The response does not answer the user's request for a Koldskål recipe. Instead, it provides a list of ingredients that appear to be for a different type of dish entirely.The generated feedback is extremely brief and fails to address the multiple issues present in the response. It only states that the recipe for Koldskål is not provided, which is accurate but not comprehensive. The reference feedback, on the other hand, provides a detailed analysis of the problems, including factual errors, relevance, intelligibility, and logical errors. It also offers constructive suggestions for improvement. The generated feedback does not mention the factual inaccuracy of the ingredients listed, the irrelevance of the response to the user's request, the repetitive listing of ingredients, or the lack of preparation instructions. It also does not provide any guidance on how the response could be improved. Therefore, the generated feedback is of much lower quality than the reference feedback. Score: 2 - ---------------------------------------- # Subjective Evaluation w/o. Reference Feedback The generated feedback correctly identifies that the response does not provide a recipe for Koldskål. The response lists ingredients that are not related to the traditional Danish dish Koldskål, which is a sweet cold soup typically made with buttermilk, eggs, sugar, vanilla, and lemon. Instead, the response includes a nonsensical list of ingredients that are repeated multiple times and are more in line with a vegetable or fruit salad rather than a Danish dessert soup. The feedback is succinct and directly addresses the main issue with the response, which is the absence of an actual Koldskål recipe. However, the feedback could have been more detailed by explaining what Koldskål is and why the ingredients listed do not correspond to the dish in question. Score: 8Figure 6 : One case in subjective evaluation of QA task. GPT-4 provides a more reasonable rationale and score given the high-quality feedback as a reference. Generated feedback is brief, cannot point out flaws, and provides rich information for revision, indicating its low quality. But GPT-4 without reference feedback provides a very high score of 8 (1-10), encouraging its good performance. Following previous works [46, 81] , the Likert scores and the average number of unique tokens in generated critiques are shown in Figure 7 . It can be found that there is almost no relationship between the number of tokens and the Likert scores generated by GPT-4 in the subjective evaluation of three critique dimensions, owing to the concise and precise reference critiques in the prompt.The overall scores of LLMs on these four critique dimensions are calculated to reflect their overall capability. For objective evaluation, the overall scores are the average scores over four critique dimensions, ranging from 0 to 100. Since Spearman scores range from -1 to 1, they are first normalized into (0, 100) before averaging. For subjective evaluation, since metafeedback does not require textual critiques, the overall scores are set as the average of feedback, comparison and correction scores, ranging from 1 to 10.You are given: ⋆ a given user query or instruction ⋆ a generated response by a large-scale language model ⋆ a textual feedback analyzes the response ⋆ a reference high-quality feedback as reference # Given Data -### Question: What is some cool music from the 1920s? ### Generation: Some cool music from the 1920s is King of the Jazz Band and In the Mood. ### Reference Feedback (Score of 8): The response contains a factual error. "In the Mood" is not from the 1920s, but was recorded in 1939 by Glenn Miller. Also, "King of the Jazz Band" is not a recognizable song title from any era. This could lead to confusion for the user. The model should ensure it provides accurate and recognizable song titles from the 1920s. ### Generated Feedback: The response provides two examples of cool music from the 1920s, which are "King of the Jazz Band" and "In the Mood." However, it would be more helpful if the response could provide additional context or information about these songs or the genre of music they belong to. For example, mentioning that "King of the Jazz Band" was performed by Paul Whiteman's orchestra, which was one of the most popular jazz bands of the time, or that "In the Mood" was a hit song by Glenn Miller's orchestra and became an iconic piece of swing music, would make the response more informative and engaging. Additionally, providing a few more examples of cool music from the 1920s would give the reader a broader understanding of the musical landscape of that era. Overall, while the response is relevant and understandable, it can be improved by adding more depth and context. -# Very Important Detail!!! 1. If you think the generated feedback is better then reference feedback, you could provide score higher than 8. 2. please first generate your feedback and explanation for the generated feedback by comparing it with reference feedback, and then you must generate the score following the format 'Score: x', where x is the score range from 1 to 10. ---------------------------------------- # Chain-of-thought evaluation by GPT-4: The generated feedback fails to identify the factual inaccuracies present. The reference feedback correctly points out that "In the Mood" is not from the 1920s but from 1939, and it also notes that "King of the Jazz Band" is not a recognizable song title. The generated feedback, on the other hand, does not address these issues at all. Instead, it suggests adding more context and examples to make the response more informative, which, while potentially useful, does not correct the fundamental errors. The generated feedback's suggestion to provide additional context about the songs and the era is a good one, but it is based on the assumption that the provided song titles are correct and relevant, which they are not. Therefore, the generated feedback is not helpful in improving the translation's accuracy or fluency and does not align with the high-quality reference feedback. # Score: 2 Figure 8: One case of evaluating feedback generation on chat task. The response is high-quality, generated by the Openbuddy-70B model, obtaining a score of 5 (1) (2) (3) (4) (5) (6) (7) . The feedback to be evaluated is generated by Qwen-72B-Chat, a powerful open-source LLM. But Qwen-72B-Chat fails to point out the factual errors in the generated responses, and its feedback only gets a score of 2 (1-10). The resources to understand this example can be found in https://en.wikipedia.org/wiki/In_the_ Mood and https://en.wikipedia.org/wiki/King_of_Jazz.You are given: ⋆ a source sentence in English ⋆ a generated response A by a large-scale language model ⋆ a generated response B by another large-scale language model ⋆ a textual comparison analyzes the response ⋆ a reference high-quality comparison-based feedback as reference # Given Data -### Translation: Milhaud also used jazz idioms, as in his Suite for clarinet, violin and piano. ### Translation A: 米哈伊尔德也曾使用爵士乐的音调，如他的长笛、小提琴和钢琴的组曲。 ### Translation B: 米尔豪德也使用爵士乐的习语，如他在长号、小提琴和钢琴的四重奏中所 使用的。 ### Reference Feedback (Score of 8): Both translations have inaccuracies. In Translation A, "clarinet" is incorrectly translated as "长笛" (flute). In Translation B, "clarinet" is incorrectly translated as "长 号" (trombone). Moreover, in Translation B, "Suite" is incorrectly translated as "四重奏" (quartet). However, Translation A correctly translates "Suite" as "组曲". Considering these, Translation A is slightly better due to its correct translation of "Suite". ### Generated Feedback: Translation A is more accurate than Translation B. The original sentence mentions "jazz idioms" which is translated correctly as "爵士乐的音调" in Translation A. However, Translation B uses "爵士乐的习语" which does not convey the same meaning as "idioms." Additionally, the original sentence mentions "Suite for clarinet, violin and piano" which is translated correctly as "长 笛、小提琴和钢琴的组曲" in Translation A, but incorrectly as "长号、小提琴和钢琴的四重奏" in Translation B. Therefore, my preference would be for Translation A as it is more accurate and faithful to the original sentence. -# Very Important Detail!!! 1. If you think the generated feedback is better then reference feedback, you could provide score higher than 8. 2. Please first generate your feedback and explanation for the generated feedback by comparing it with reference feedback, and then you must generate the score following the format 'Score: x', where x is the score range from 1 to 10. ----------------------------------------- # Chain-of-thought evaluation by GPT-4: The generated feedback correctly identifies that Translation A is more accurate than Translation B. However, it makes a significant factual error by stating that "长笛" is the correct translation for "clarinet," which is incorrect. The correct translation for "clarinet" should be "单簧管" or "黑管." This error is critical as it misleads the evaluation of the accuracy of the translations. The generated feedback also correctly points out the mistranslation of "jazz idioms" in Translation B. However, it fails to mention that "爵士乐的音调" in Translation A is also not an entirely accurate translation of "jazz idioms," as "音调" refers more to musical tones rather than idioms or phrases. Additionally, the generated feedback does not address the error in Translation B where "Suite" is translated as "四重奏" (quartet), which is a significant mistake as it changes the type of musical composition being discussed. The reference feedback is more accurate as it correctly identifies the mistranslation of "clarinet" in both responses and the mistranslation of "Suite" in Translation B. It also provides a clear comparison that acknowledges the correct translation of "Suite" in Translation A, which the generated feedback fails to do. In terms of intelligibility, both feedbacks are clear and easy to understand. They both maintain relevance by addressing the accuracy of the translations in relation to the original sentence. Considering these points, the generated feedback has a factual error and misses a critical translation error, making it less effective than the reference feedback. # Score: 4 ----------------------------------------- # Chain-of-thought evaluation by GPT-4: The generated correction "然而，第一批起义者攻占了Speen Hill的防御工事。" addresses the feedback points effectively: 1) Fluency: The generated correction replaces "冲了过去" with "攻占 了," which is more formal and appropriate for the historical context of a military action. This improves the fluency of the sentence. 2) Readability: By using "攻占了" (captured), the generated correction clarifies the action taken by the rebels. It removes the confusion caused by "带着Speen Hill的工事冲 了过去" in the original translation, making it clear that the rebels overran the entrenchments rather than physically carrying them. 3) Translationese: The term "带着" is removed in the generated correction, thus eliminating the direct translation issue and making the sentence sound more natural in Chinese. Comparing the generated correction to the reference correction "然而，起义者的第一波冲击冲破 了斯平山的壕沟。", both sentences convey the same meaning and are free from translationese. The reference correction uses "冲击冲破了" (assault broke through), which is also a clear and accurate description of the rebels' action. The reference correction includes the term "壕沟" (trenches), which is a specific type of entrenchment, while the generated correction uses "防御工事" (defensive fortifications), a more general term. Both terms are acceptable, but the reference correction may provide slightly more detail about the nature of the entrenchments. Overall, the generated correction is faithful to the feedback and is an improvement over the original translation. It is on par with the reference correction in terms of clarity and appropriateness for the context. # Score: 8 ----------------------------------------- # Score: 4 ---------------------------------------- # Generation: Decision: A. Translation A is more accurate and faithful to the original sentence. It correctly translates "jazz idioms" as "爵士乐的音调," which conveys the intended meaning of Milhaud's use of jazz elements in his music. On the other hand, translation B mistranslates "Suite for clarinet, violin and piano" as "长号、 小提琴和钢琴的四重奏," which is not an accurate representation of the original work. Additionally, the use of "米尔豪德" instead of "米哈伊尔德" may cause confusion for readers who are familiar with the composer's name. Overall, translation A is a better quality translation. Table 19 and Table 20 show the overall evaluation results for different qualities granularities on the subjective evaluation of the test and dev set the feedback, comparison, and correction critique dimensions. Table 21 and Table 22 show the overall evaluation results for different qualities granularities on the objective evaluation of the test and dev set the feedback, comparison, and correction critique dimensions.Table 23 and Table 24 show evaluation results on each tasks (test set) for the feedback and comparisonbased feedback dimensions. Table 25 and Table 26 show complete evaluation results on each tasks (dev set) for the feedback and comparison dimensions. Table 27 and Table 28 show complete evaluation results on each task (test and dev set) for the correction dimension. In this section, we provide more details and comparison between LLMs and human performance. Specifically, we conduct the human annotation of the subjective tasks on the CRITICEVAL test set, and the overall human-level performance is shown in Table 29 . Note that the cohort and corresponding set of human critiques does not represent the best possible human performance; instead, they represent the capability of annotators selected for this human performance annotation of the CRITICEVAL test set. It can be found that the human-level significantly outperforms GPT-4 on the objective task, while it is inferior to GPT-4 on the subjective evaluation. Therefore, we conduct the Quantitative and Qualitative Analysis to understand the performance gap between humans and GPT-4 in subjective evaluation.Quantitative Analysis We conduct the fine-grained failure modes analysis, and the distribution of each failure mode for feedback, comparison and correction dimensions are shown in Table 30 , Table 31 and Table 32 . The numbers in following tables indicate the frequencies of error types in GPT-4 and human-written critiques. The detailed description of each failure mode can be found in Section 6.8. As for the feedback and comparison dimensions, the distribution of E1 (missing issues), E2 (missing suggestions or low-quality suggestions), and E7 (insufficient analysis) in humanwritten critiques is significantly higher than that of GPT-4. In contrast, the distribution of other error types is significantly lower. As for the correction dimension, human annotators usually do not follow suggestions in the provided feedback (E9) and generate additional errors (E11). Through communicating with the annotators, we notice that the primary cause of this issue is that some tasks require domain-specific knowledge, and the lack of this knowledge among human annotators results in lower-quality corrections. In summary, the human-written critiques are often less comprehensive than GPT-4, significantly reducing the quality. In contrast, the mistakes in human-written critiques are significantly less than that of GPT-4. This phenomenon is consistent with our preliminary study and recent findings [79, 6] , further proving the effectiveness and reasonableness of leveraging the human-in-the-loop pipeline to construct comprehensive and accurate reference critiques. Qualitative Analysis We inspect the human-written critiques in the subjective evaluation tasks to understand the source of the performance difference. In general, human annotators write fewer comments than LLMs, and the comments are usually general and brief. Besides, many tasks involve domain-specific knowledge that humans may lack, but GPT-4 excels in (albeit with potential hallucinations).We extensively evaluate widely used open-source and closed-source LLMs of different sizes on CRITICEVAL to understand the current progress in this field, including (1) instruction-tuned LLMs;(2) critique-tuned LLMs; and (3) reward models. To reproduce evaluation results, the greedy search is employed for open-source LLMs, and the temperature factor is set as 0 for closed-source LLMs, i.e., decoding randomness is minimum.The inference procedures of all these evaluated LLMs in this paper are conducted in an A800 server with 8 GPU cards, each with 80G CUDA memory. The vLLM [82] and LMDeploy [83] packages are used to speed up the inference, and the average inference time cost for each LLM is 1.25 hours.For closed-source LLMs, we test GPT-4, Claude, Gemini-Pro, PaLM, GPT-3.5-turbo, etc. For open-source LLMs, we test numerous LLM series including Mistral [49] , LLaMA2 [37] , Baichuan2 [84] , Qwen9 [21] , InternLM2 [48] , WizardLM [85] , Vicuna [86] , Yi, and DeepSeek [50] , etc.Recent works have proven that fine-tuning LLMs on critiques generated by GPT-4 significantly improves LLM's critique ability [11, 30, 24, 12] . Llama-2-13B fine-tuned on GPT-4's critique could achieve close critique ability to GPT-4, and even outperform much larger model, like Llama-2-70B.In this paper, we name the LLMs fine-tuned on critiques dataset Critique-tuned LLMs, and we comprehensively evaluate critique-tuned LLMs on our proposed CRITICEVAL: (1) TigerScore [30] ;(2) Auto-J-13B [11] ; and (3) UltraCM [12] .However, there are two popular critique-tuned LLMs are not evaluated in CRITICEVAL. The reasons are listed as follows: (1) InstructScore [24] can only be used to evaluate limited tasks, like data2text and commonsense, thus we donot test InstructScore in our work; (2) Prometheus [14] are not evaluated because of its high dependence on the criteria question, score rubrics and reference answers, which is not fully covered in our benchmark.Moreover, we show CRITICEVAL can also be used to evaluate reward models [87] . There are lots of reward models that can be publicly accseed. We only evaluate three representative reward models, and leave the evaluation on other reward models in our future work [58] : (1) UltraRM-13B [12] ; (2) Ziya-7B [52] ; (3) SteamSHP [53] .Beyond the simplified average scores from 1 to 10 in the subjective evaluation of CRITICEVAL, we also categorize the textual critiques of each LLM into three quality intervals for more interpretable analysis: (1) Low-quality critiques (1-3); (2) Medium-quality critiques (4-6); (3) High-quality critiques (7) (8) (9) (10) . The results of five representative LLMs on feedback, correction, and comparionbased feedback dimensions are shown in Figure 13 . It can be found that GPT-4-turbo exhibits strong critique ability and barely generates low-quality critiques. In contrast, the critiques generated by the Llama-2-70B-Chat are usually low-quality. Besides, the ratio of low-quality critiques generated by some LLMs, like Llama-2-70B-Chat and Qwen-72B-Chat, are very high, indicating that they have a lot of room for improvement.In this section, we analyze the details and cases about three kinds of error patterns in responses: (1) obvious error; (2) complex error; (3) subtle error. Specifically, we ask human annotators to summarize the common error cases after they annotate all the textual critiques in CRITICEVAL, and categorize them into obvious error, complex error, and subtle errors in Table 33 . It should be noted that these three error patterns may have other specific error cases in nine domains. However, it is difficult to exhaust all the error case. Thus, our motivation is to list, annotate, and analyze as many as possible to ensure the accuracy of our experimental results.Q Likert Score for Responses Construct Multilingual CRITICEVAL Following the previous work [89] , CRITICEVAL could be translated to various languages, especially low-resource languages, with human annotation for revising translation inaccuracies. the most direct way is to translate CRITICEVAL into various languages, with human annotation for revising translation inaccuracies.Evaluate Multilingual CRITICEVAL While the reliability of objective evaluation could be ensured, the reliability of subjective evaluation is limited by the multilingual capability of the judge model (GPT-4). We recommend back-translating multilingual critiques into English and evaluating them within English CRITICEVAL.• Examples of negative societal impacts include potential malicious or unintended uses (e.g., disinformation, generating fake profiles, surveillance), fairness considerations (e.g., deployment of technologies that could make decisions that unfairly impact specific groups), privacy considerations, and security considerations. • The conference expects that many papers will be foundational research and not tied to particular applications, let alone deployments. However, if there is a direct path to any negative applications, the authors should point it out. For example, it is legitimate to point out that an improvement in the quality of generative models could be used to generate deepfakes for disinformation. On the other hand, it is not needed to point out that a generic algorithm for optimizing neural networks could enable people to train models that generate Deepfakes faster. • The authors should consider possible harms that could arise when the technology is being used as intended and functioning correctly, harms that could arise when the technology is being used as intended but gives incorrect results, and harms following from (intentional or unintentional) misuse of the technology. • If there are negative societal impacts, the authors could also discuss possible mitigation strategies (e.g., gated release of models, providing defenses in addition to attacks, mechanisms for monitoring misuse, mechanisms to monitor how a system learns from feedback over time, improving the efficiency and accessibility of ML).This work has the same name as the previous CRITICBENCH[9].More considerations for utilizing human-in-the-loop annotation pipeline are described in Appendix G.Subjective tasks represent five tasks (translation, general chat, QA, summary and harmlessness).https://www.anthropic.com/news/claude-3-familyhttps://ai.meta.com/blog/meta-llama-3/https://hf-mirror.com/datasets/lmsys/lmsys-arena-human-preference-55kQwen-1.5 serie LLMs are only evaluated in the meta-feedback critique dimension. 


Decision: This work presents an analysis of the evaluation capabilities of large language models (LLMs) at four different tasks: (1) pointwise evaluation of generated responses with textual and numerical assessments, (2) response correction, (3) pairwise response comparison; (4) meta-feedback – the evaluation of generated textual evaluations. Human annotations are collected on 9 specific application scenarios to facilitate the evaluation of the 4 evaluation tasks. A comprehensive evaluation is then performed on 35 LLMs using the collected human annotations as gold references with the assistance of GPT-4.  

The reviewers mostly agree on the following strengths and contributions of this work:  
1. The importance of new human annotation collection in facilitating the evaluation of LLMs’ evaluation capabilities on the four tasks studied.  
2. The comprehensiveness of the evaluation performed, covering 35 LLMs, 9 application scenarios, and 4 evaluation tasks.  
3. The analysis performed in this paper is thorough and offers interesting insights.  

The major concerns the reviewers raised include:  
1. The reliance on GPT-4 in the evaluation pipeline, considering GPT-4 may not be a reliable and unbiased evaluator.  
2. Unclarity of the cost of the evaluation process.  
3, Lack of discussion of multilingual evaluation.  
During the rebuttal period, the authors provided responses that clarified some of the above concerns. Specifically, regarding the reliance on GPT-4, this work has already performed a meta-evaluation of GPT-4 regarding performing subjective evaluations in Section 6.2, which provides an assessment of its reliability. However, the highest correlation achieved between GPT-4 and human annotations is around 66.2, which may not be high enough to demonstrate that GPT-4 is a robust evaluator. That said, the use of GPT-4 is largely justified because it can greatly improve the evaluation efficiency.

This work could be improved by the following:  
1. A clearer and more thorough discussion of the limitations and risks of using GPT-4 as the judge in evaluation.  
2. Clear description and analysis of the human annotation quality. One major contribution of this work is the collected human annotation,  
 and it is of great importance that the human annotations are reliable. However, there is a lack of quantitative analysis of the human annotation quality, such as the inter-annotator agreement rate of pointwise scoring, etc. These statistics are important to demonstrate the quality of the collected annotations. Related work such as LLMBar [1] put a great emphasis on this reliability since it determines whether the evaluation performed on the collected annotations is reliable.

Reviews: review: paper_summary: paper_summary: This study constructs a comprehensive framework for LLM-based evaluation, encompassing data construction, human/machine annotation, and result analysis. It defines a single evaluation framework that covers various tasks and response types. Although previous studies have evaluated different tasks and response types, they often lacked comprehensive analysis, making it difficult to understand the relationships between various factors during evaluation. This research aims to address this gap. Additionally, it examines the reliability of evaluations based on the types of judge models and target models, as well as the importance of human annotation data.
Through extensive experiments and comprehensive analysis, this study demonstrates consistent trends across various tasks and highlights the importance of utilizing human-annotated data in evaluations.
strength_weakness: strength_weakness: 1. One important metric for evaluation models, the ability to revise its generation with critique, is excluded. As mentioned in the paper, there is active research on improving generation performance through LLM’s self-feedback during the inference stage. It is necessary to evaluate each model’s ability to revise existing outputs when provided with critique.
2. Although this study addresses the translation task, it excludes the critique ability in other multilingual contexts. The critique ability of LLMs in various languages other than English is crucial for ensuring diversity, and additional data collection on this aspect seems necessary.
questions: questions: 1. What is the pattern of score changes when using feedback from other LLMs in Table 5, based on the quality of the feedback from these other LLMs?
limitations: limitations: Yes, this study clearly mentions its limitations in the conclusion.
paper_summary: paper_summary: The paper addresses the need for a comprehensive evaluation of the critique ability of large language models (LLMs) for self-improvement and alignment with human outcomes. Current evaluation methods are critiqued for their limited scope and reliability. The authors propose CRITICEVAL, a benchmark designed to evaluate LLMs across four critique dimensions: feedback, comparison, correction, and meta-feedback, covering nine diverse task scenarios including NLP, alignment, and reasoning tasks. While CRITICEVAL incorporates human-annotated references to enhance reliability, it heavily relies on GPT-4 for evaluations, raising concerns about generalisability across other LLMs. Evaluations of 35 LLMs demonstrate CRITICEVAL's effectiveness but also highlight the inherent difficulties in critiquing complex tasks and the inverse relationship between critique and response quality. Although promising, the reliance on human annotation and the potential biases introduced by using a single LLM for baseline evaluations could limit its broader applicability. The release of datasets and evaluation tools is a positive step towards fostering further research.
strength_weakness: strength_weakness: Even with the mention of incorporating Chinese, I believe there should be a serious discussion on how such evaluation pipelines and datasets would function for low-resource languages (Chinese is not one). Many of the large LLMs have multilingual capabilities and their generation of responses are more likely to have higher error rates and as such being able to do critical evaluation in such use-cases is important. 

The computational cost and real cost of setting up the CRITICEVAL pipelines should be spelled out.

It is not clear if IRB/Ethical clearance was obtained as the checklist response states that IRB *would* be easy to obtain. This is a concern as such I will be referring this for ethics review. It is appreciated that information was provided in Appendix B and G, but whether IRB was obtained or not should have a clear YES or NO statement.
questions: questions: 1. How do you protect against errors in the underlying tasks datasets. The explosion of many task evaluation sets, even with the best intentions of researchers means that we have compounding effects of source errors (e.g. in Translation), how would this affect your work and how would you mitigate against it?
2. Ultimately how many people are involved and computational cost of such an exercise as this affects replication ability of this study to cover some of the limitations you hilighted?
limitations: limitations: The limitations are written in Appendix A. They are clear.
paper_summary: paper_summary: This paper introduces CriticEval, a benchmark designed to comprehensively and reliably evaluate the critique ability of large language models (LLMs). It assesses critique capabilities across four dimensions (feedback, comparison, correction, and meta-feedback) and nine diverse task scenarios, using both scalar-valued and textual critiques for responses of varying quality. The benchmark was constructed using a human-in-the-loop pipeline, with initial critiques generated by GPT-4 and refined by human experts. CriticEval employs both objective metrics and subjective evaluation by GPT-4 with human-annotated reference critiques. Key findings from evaluating 35 LLMs include: GPT-4's high correlation with human judgments when using reference critiques, some open-source LLMs approaching closed-source models in performance, and insights into how critique difficulty varies by task type, response quality, and critique dimension.  CriticEval could be used as a comprehensive and reliable tool for assessing LLM critique capabilities.
strength_weakness: strength_weakness: - The biggest concern of the dataset is that it relies heavily on GPT-4 for initial critique generation and evaluation. This could introduce a bias favoring models such as GPT-4 and models trained on GPT-4 distilled data. The human-in-the-loop process might not fully mitigate this bias, especially if annotators are influenced by GPT-4's initial outputs. A more diverse set of models or purely human-generated critiques for the benchmark could have provided a more neutral evaluation framework. 
- The paper doesn't adequately address the scalability of CRITICEVAL for evaluating future language models. Additionally, the reliance on GPT-4 and human experts for evaluation might make it challenging for other researchers to fully reproduce or extend the benchmark. 
- Insufficient analysis of failure modes: While the paper presents overall performance metrics, it doesn't delve deeply into the specific ways in which models fail at critique tasks. A more detailed error analysis could provide valuable insights into the limitations of current LLMs and guide future research more effectively.
- Lack of comparison to human performance: The paper doesn't provide a clear comparison between LLM performance and human performance on these critique tasks.
questions: questions: How did you evaluate the human's performance during the benchmark construction phase?

The benchmark covers four settings:
1. Providing feedback

Besides positional bias, did you explore any other biases such as bias to length, style or certain words?

The Complete Human-level Performance
comment: Dear Reviewer kJKF,

We really appreciate your valuable feedback during the review phase, and thank you for raising the overall score assigned to our paper.

Although we have made our best efforts, the bias of GPT-4 may still not be completely eliminated. The human-in-the-loop annotation pipeline is the trade-off solution for collecting comprehensive and accurate critiques by considering scalability and reliability. We will discuss it in more detail in the Limitation Section of our revised paper.

If you have any further questions or concerns, we are more than happy to address them!

I appreciate the author's response, which slightly resolves my concerns. However, I still have concerns about the bias in pure GPT-4 assisted annotation, which is a fundamental limitation of the methodology. Given the new results, I would like to slightly raise my overall score from 4 to 5.
Thank you for your responses.
Thanks for responding to my questions.
Dear Ethic Reviewer 5NeV,

Thanks for your review comments and suggestions about our paper. 

`We want to emphasize that:` We have submitted an application to the Institutional Review Board (IRB). After evaluation, the committee determined that the human annotation for the critique task posed no ethical concerns, and accordingly, we conducted the human annotation.

Besides, our work only includes crowdsourcing to collect annotation data for critiques, and it does not involve collecting personal information from the annotators or has any potential impact on the annotators personally (such as psychological, physiological, or social impacts). Therefore, no human subjects are studied in our work.

We will updated the answer and justification to resolve the uncertainty as follows based on your suggestions:

---

`15. Institutional Review Board (IRB) Approvals or Equivalent for Research with Human Subjects`

`Answer`: `[Yes]`

`Justification`: We have submitted an application to the Institutional Review Board (IRB). After evaluation, the committee determined that the human annotation for critique task posed no ethical concerns, and accordingly, we conduct the human annotation. Besides, we have adequately addressed minimal ethical concerns by following efforts: ensuring the fairness of the data collection by selecting a diverse group of annotators, providing clear guidelines, and compensating the annotators well, as described in Appendix B and Appendix G. Therefore, these efforts make sure our work does not violate the NeurIPS Code of Ethics.

Dear Reviewer kJKF,​

We would like to thank you for the thoughtful and constructive feedback and appreciate that you agree on the strengths of our paper.​

We provided details and analysis to address your concerns during the rebuttal. In this response, we complete the human performance annotation of the subjective tasks on the CriticEval test set, and the overall human-level performance is shown as follows. ​

**Note that the cohort and corresponding set of human critiques do not represent the best possible human performance; instead, they represent the capability of annotators selected for this human performance annotation of the CriticEval test set.**

||Feedback Sub.|Feedback Obj.|Comparsion Sub.|Comparison Obj.|Correction Sub.|Correction Obj.|
|-|-|-|-|-|-|-|
|GPT-4|**7.84**|63.54|**7.89**|57.33|**7.69**|69.67|
|Human|5.61|**67.69**|5.22|**60.67**|6.63|**75.69**|

> As described in Section 5, objective scores (Obj.) for feedback, comparison, and correction are correlation, accuracy, and pass rate. Subjective scores (Sub.) for feedback, comparison, and correction are Likert scores (1-10) generated by GPT-4 with human-annotated critiques as references.

**`Experimental Results:`** As shown in the Table above, it can be found that the human level significantly outperforms GPT-4 on the objective task, while it is inferior to GPT-4 on the subjective evaluation.

---

Then, we conduct the Quantitative and Qualitative Analysis to understand the human performance in subjective evaluation.

### **Quantitative Analysis**

The distribution of failure modes for humans and GPT-4 is shown in the following tables. The numbers in the tables indicate the frequencies of error types in critiques. The descriptions of failure modes are placed in Table 1 of **"Global Response - Fine-grained Failure Modes."**

|Feedback|E1|E2|E3|E4|E5|E6|Other|
|-|-|-|-|-|-|-|-|
|GPT-4|17.99|18.71|**16.37**|**15.83**|**10.07**|**14.93**|6.12|
|Human|**21.18**|**24.48**|11.36|15.27|9.06|12.13|**6.52**|

|Comparison|E1|E2|E3|E4|E5|E6|E7|E8|Other|
|-|-|-|-|-|-|-|-|-|-|
|GPT-4|16.67|11.02|**11.29**|**15.59**|**4.3**|**6.99**|19.35|**12.1**|**2.69**|
|Human|**19.71**|**15.29**|7.65|9.51|3.82|4.8|**24.9**|11.67|2.65|

|Correction|E9|E10|E11|Other|
|-|-|-|-|-|
|GPT-4|23.46|**43.83**|21.6|**11.11**|
|Human|**29.38**|36.88|**25**|8.75|

**`Experimental Results:`** As for the feedback and comparison dimensions, the distribution of E1 (missing issues), E2 (missing suggestions or low-quality suggestions), and E7 (insufficient analysis) in human-written critiques is significantly higher than that of GPT-4. In contrast, the distribution of other errors (most are mistakes in critiques) is much lower.

As for the correction dimension, human annotators usually do not follow suggestions in the provided feedback (E9) and generate additional errors (E11). Through communicating with the annotators, we notice that the primary cause of this issue is that some tasks require domain-specific knowledge. The lack of this knowledge among annotators leads to lower-quality corrections. This phenomenon aligns with the findings of recent work [1].

**`Conclusion:`** The human-written critiques are often less comprehensive than GPT-4, significantly reducing the quality. In contrast, the mistakes in human-written critiques are significantly less than that of GPT-4. This phenomenon is consistent with our preliminary study and recent findings [1], further proving the reasonableness of using the human-in-the-loop pipeline to collect comprehensive and accurate critiques (**as described in Q2-A2**).

### **Qualitative Analysis**

We inspect the human critiques in the subjective evaluation. We notice that human annotators generally write fewer comments than LLMs, and comments are usually general and brief. Besides, many tasks involve domain-specific knowledge that humans may lack, but GPT-4 excels in (albeit with potential hallucinations).

### **Summary**

We provide the human-level performance for the CriticEval test set. The human performance is better than GPT-4 on the objective split, while it is inferior to GPT-4.

**`We wish to emphasize that:`** Although our first submission lacks **pure** human performance, our reference critiques obtained through the human-in-the-loop pipeline could serve as very close candidates for the best possible human performance. During the subjective evaluation, the quality score of reference critique is anchored to 8 (overall 1-10 score range), serving as a relative scoring pivot, which is helpful in analyzing the performance gap between LLMs and human.

We will supplement experimental results and analysis into our revised paper.

We hope these responses address the concerns. We are happy to discuss further comments and suggestions. If the reviewer finds our response adequate, we would appreciate it if the reviewer considers raising the score.
