###### Abstract

As language models (LMs) become capable of handling a wide range of tasks, their evaluation is becoming as challenging as their development. Most generation benchmarks currently assess LMs using _abstract evaluation criteria--_like helpfulness and harmlessness--which often lack the flexibility and granularity of human assessment. Additionally, these benchmarks tend to focus disproportionately on specific capabilities such as instruction following, leading to _coverage bias_. To overcome these limitations, we introduce the BiGgenBench, a principled generation benchmark designed to thoroughly evaluate nine distinct capabilities of LMs across 77 diverse tasks. A key feature of the BiGgenBench is its use of instance-specific evaluation criteria, closely mirroring the nuanced discernment of human evaluation. We apply this benchmark to assess 103 frontier LMs using five evaluator LMs. Our code, data, and evaluation results are all publicly available 1.

This paper is mainly divided into three parts.
* In Section 3, we explain the evaluation protocol and construction process of the BiGGen Bench, noting that all instances were crafted through a human-in-the-loop approach.
* In Section 4, we share the evaluation results of 103 LMs. Our findings indicate that with fine-grained evaluation, capability-wise performance changes smoothly and predictably with model size scaling. We also identify that gaps in reasoning and tool usage capabilities between pre-trained and post-trained LMs, as well as between post-trained and proprietary LMs, do not narrow, whereas gaps in instruction-following capabilities significantly narrow.
* In Section 5, we study whether the scores acquired from evaluator LMs are reliable. To do this, we measure the scoring correlation between evaluator LMs and human evaluators. Our findings indicate that the correlations are statistically significant across all capabilities. Alongside, in Appendix E, we explore a bag of tricks to elevate open-source evaluator LMs to perform evaluations as effectively as GPT-4, aiming for fair and accessible evaluations.

Additionally, to offer further insights into advancing the frontier LMs, we host two interactive websites: one displays visualizations of outputs from the 103 evaluated LMs, complete with scores and detailed verbal feedback highlighting limitations and suggesting areas for improvement 2; the other features a leaderboard presenting scores across each capability as well as the average scores 3.

LM evaluation benchmarksLM evaluation benchmarks can primarily be divided into two categories: classification benchmarks and generation benchmarks. Classification benchmarks require the LM to comprehend a question and select from a set of options, making it straightforward to measure the LM's performance by verifying if the output matches the answer Hendrycks et al. (2020); Srivastava et al. (2022); Gao et al. (2021); Beeching et al. (2023); Li et al. (2023); Son et al. (2024). On the other hand, generation benchmarks prompt an LM to produce a free-form response to a given prompt Chiang et al. (2023); Zheng et al. (2023); Li et al. (2023); Bai et al. (2024); Dubois et al. (2024); Longpre et al. (2024), and it is often unclear how to

Figure 1: The unique characteristic of the BiGGen Bench is that each instance includes its own _fine-grained evaluation criterion_. This enables more precise assessments of performance tailored to the specific characteristics and challenges of each instance. In contrast, coarse-grained evaluation criteria (_e.g._, helpfulness, harmlessness) Li et al. (2023); Zheng et al. (2023) may overlook subtle nuances and specific details, while domain-specific criteria Ye et al. (2023) might not account for the variability within individual instances.

 

assess the quality of the output. Previous studies have measured the lexical or semantic similarity between the predicted free-form response and the reference answer to quantify the quality of the output [12, 30, 48, 57, 69, 7]. However, the critical drawback is that it fails to identify false negatives, where the output is satisfactory but different from the reference answer [18, 48, 48, 48]. Recent studies have shown that prompting proprietary LMs (_e.g._, GPT-4) to judge the quality of free-form responses often yields evaluation results that correlate more closely with human judgments [48, 49, 57, 69, 70]. Furthermore, follow-up studies suggest that open-source LMs that could also function as evaluators [46, 48, 49, 57, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, 192, 193, 194, 195, 196, 197, 198, 199, 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210, 211, 222, 223, 224, 225, 226, 227, 228, 229, 230, 231, 232, 233, 234, 235, 236, 237, 238, 239, 240, 241, 242, 243, 244, 245, 246, 247, 248, 249, 250, 251, 252, 253, 254, 255, 256, 257, 258, 259, 260, 261, 262, 263, 264, 265, 266, 267, 268, 269, 270, 271, 272, 273, 274, 275, 276, 277, 278, 279, 280, 281, 282, 283, 284, 285, 286, 287, 288, 289, 290, 291, 292, 293, 294, 295, 296, 297, 298, 299, 300, 301, 302, 303, 304, 305, 306, 307, 308, 309, 310, 311, 323, 334, 335, 336, 337, 341, 342, 343, 344, 345, 346, 347, 348, 349, 350, 351, 352, 353, 354, 355, 356, 357, 358, 359, 360, 361, 362, 363, 364, 365, 366, 367, 368, 369, 370, 371, 372, 373, 374, 375, 376, 377, 378, 379, 380, 381, 382, 383, 384, 385, 386, 387, 388, 389, 390, 391, 392, 393, 394, 395, 396, 397, 398, 399, 400, 401, 402, 403, 404, 405, 406, 407, 408, 409, 409, 410, 411, 422, 443, 445, 446, 447, 448, 459, 460, 407, 409, 411, 422, 443, 449, 451, 452, 453, 454, 455, 456, 457, 458, 459, 461, 462, 463, 464, 465, 466, 467, 468, 469, 470, 471, 472, 473, 474, 475, 476, 477, 478, 479, 480, 481, 482, 483, 484, 485, 486, 487, 488, 489, 490, 411, 422, 443, 449, 491, 445, 447, 448, 492, 493, 494, 495, 496, 497, 498, 499, 400, 411, 422, 443, 449, 499, 410, 412, 443, 449, 413, 449, 414, 415, 449, 416, 417, 418, 419, 420, 421, 443, 449, 434, 449, 450, 451, 452, 453, 454, 456, 457, 458, 459, 460, 461, 462, 463, 464, 465, 466, 467, 468, 469, 470, 471, 472, 473, 474, 475, 476, 478, 479, 480, 482, 483, 484, 485, 486, 487, 488, 489, 490, 491, 492, 493, 494, 495, 496, 497, 498, 499, 400, 411, 422, 443, 449, 499, 410, 413, 449, 414, 415, 449, 416, 417, 419, 420, 421, 443, 449, 434, 449, 450, 451, 452, 453, 454, 456, 457, 458, 459, 460, 461, 462, 463, 464, 465, 466, 467, 468, 469, 470, 471, 472, 473, 474, 475, 476, 478, 479, 480, 483, 485, 486, 487, 488, 489, 490, 491, 492, 493, 494, 495, 496, 497, 498, 499, 400, 411, 422, 443, 449, 499, 410, 423, 449, 44, 495, 496, 497, 499, 401, 498, 499, 411, 402, 493, 499, 411, 403, 499, 410, 423, 499, 424, 493, 494, 411, 434, 495, 496, 497, 498, 499, 400, 411, 402, 493, 499, 411, 404, 415, 449, 416, 417, 418, 419, 420, 423, 44, 449, 450, 451, 452, 453, 454, 456, 457, 458, 459, 460, 461, 462, 463, 465, 467, 468, 469, 470, 471, 472, 473, 475, 476, 478, 479, 480, 483, 485, 486, 487, 489, 490, 491, 492, 493, 494, 495, 496, 497, 498, 499, 400, 411, 499, 410, 499, 411, 405, 499, 411, 406, 499, 410, 412, 493, 494, 413, 495, 496, 497, 499, 410, 498, 499, 411, 400, 413, 499, 414, 499, 415, 499, 416, 499, 417, 499, 418, 499, 420, 493, 499, 410, 499, 421, 493, 499, 422, 493, 494, 495, 496, 497, 499, 400, 41 

instance-specific evaluation criteria, the criteria are confined to _easily verifiable constraints_ (_e.g._, generate a random string with exactly 20 characters, the letter {letter} should appear {N} times) which restrict their scope to instruction following. In contrast, in BiGGenBench, by employing language model evaluators, language model evaluators could flexibly assess based on arbitrary evaluation criteria (_e.g._, "Does the rationale substitute the variable x,y,z multiple times to reduce the value 560 while solving the problem?", "Does the response predict that Emma will persuade Max to refrain from breaking the castle by citing his prior experience?") hence we gather inputs across 9 distinct capabilities.

## 3 BiGGenBench: The BiG Generation Benchmark

The BiGGenBench is built in a principled top-down manner, maintaining a "capability - task - instance - evaluation criteria" hierarchy. In this section, we explain the evaluation protocol and construction process of the BiGGenBench. An explanation of the 9 capabilities and 77 tasks, along with the role of instance-specific evaluation criteria within each capability, is provided in Appendix A.

### Evaluation protocol

Each instance includes a system message, an input, a reference answer, and a scoring rubric. The scoring rubric consists of evaluation criteria and descriptions for each score, ranging from 1 to 5. Given the system message, the input, and the LM under assessment (denoted as "Response LM"), we first acquire the response. If the response LM is a post-trained LM (_i.e._, trained via instruction tuning or RLHF), we use zero-shot prompting. If the response LM is a pre-trained LM, we employ the URIAL prompt, which includes cross-task 3-shot demonstrations Lin et al. (2023). In our early experiments, we found that base LMs often generate responses in English even when the prompt requires a non-English response, a phenomenon known as "accidental translation" Xue et al. (2020); Li and Murray (2023). Therefore, for multilingual tasks, we decide to test only post-trained LMs, while both pretrained and post-trained LMs are assessed across all other capabilities.

Subsequently, the LM that functions as a judge (denoted as "Evaluator LM") takes in a single response from the response LM and generates a 5-scale Likert score (_i.e._, in a direct assessment format)/Zheng et al. (2023); Kim et al. (2024). We choose direct assessment formats over pairwise ranking formats because they allow the addition of a new response LM separately without the need to compare it with a previously existing set of response LMs. We utilize the template from PrometheusKim et al. (2023, 2024) when prompting evaluator LMs. Note that when calculating average performance scores, we do not include scores from multilingual tasks, as pre-trained LMs are not evaluated for this capability. The hyper-parameters, a list of the 103 Response LMs, a list of 5 evaluator LMs, the URIAL prompt, and the Prometheus template are included in Appendices F and G.

### Construction process

Step 1: Hand-crafting instancesWe initiated the process by having eighteen coauthors, each responsible for annotating one capability, create 25 instances across five tasks. Additionally, ten native-speaking annotators proficient in Korean, Kazakh, Bengali, Spanish, Indonesian, German, French, Arabic, Russian, and Thai were tasked with annotating ten instances each across ten tasks within the multilingual capability. Initially, the tasks were designed by the first author and subsequently refined through discussions with all annotators. The annotators were instructed to consult relevant research papers (cited in Appendix A). The first author reviewed and revised the content to correct grammatical errors, enhance fluency, and eliminate tasks that predominantly featured confusing or unchallenging instances. This review process resulted in the removal of 23 tasks, leading to a finalized set of 77 tasks with 385 instances in total. Examples of evaluation criteria from each capability are

Figure 3: **Cross-validation results by human evaluators. To maintain high quality, we exclude instances that both evaluators determine to either not fit the task or have a bad reference answer or score rubrics. For instances that only one annotator marks as low quality, we iteratively revise them.**



presented in Appendix A.

Step 2: Augmenting new instances with human demonstrationsNext, we expanded the number of instances using GPT-4-0125, focusing on quality and diversity. We maintained high quality by employing human-crafted instances from Step 1 as in-context demonstrations for each task, rather than creating new ones in a zero-shot manner. For diversity, we generated five candidates for each new instance, chose the one with the lowest semantic similarity (measured by BertScore Zhang et al. (2019)), and repeated this five times. Finally, we validated the instances and either discarded or revised any of low quality, as detailed in Step 3, resulting in a total of 770 instances across 77 tasks.

Step 3: Cross validationSubsequently, we assigned the eighteen coauthors to validate instances they had not annotated, with each reviewing 2 capabilities, 10 tasks, and 50 instances. We revised instances flagged by one annotator and eliminated those confirmed by both to be misaligned or to have poor references or rubrics. Results are shown in Figure 3. This led to the elimination of five instances, bringing the total to 765 instances across 77 tasks. Our detailed procedure is listed in Appendix B.1

Step 4: Gathering human judgmentsLastly, to verify the reliability of evaluation results from evaluator LMs (further explained in Section 5), we obtain human judgments. Specifically, from the 103 responses LMs evaluate, we select 4 LMs and ask human annotators to grade the responses. For multilingual capability, we acquire human scores for responses from 6 LMs. To ensure reliable human ratings, we employ a three-stage pipeline consisting of a recruitment stage, a qualification stage, and a main evaluation stage. The details of the human evaluation process, demographic information of the evaluators, along with annotation instructions and payment details, are listed in Appendix B.2.

## 4 Main results and analyses

We present the evaluation results of 103 LMs. Detailed capability-wise and average scores for each response LM, assessed by five different evaluator LMs, as well as the top scoring LMs for each capability, are listed in Appendix G. This section highlights key findings derived from these results. We examine the overall performance trends across differently sized pre-trained LMs (denoted as "base LMs"), post-trained LMs (denoted as "chat LMs"), the performance differences between corresponding base and chat LMs, and the gap between open-source and proprietary LMs.

Performance of base LMs increases smoothly with scaling model parameter size.The performance of 28 base LMs is displayed in Figure 4, and summarized in the upper part of Table 1. As model parameter size increases, the average performance also increases linearly on a logarithmic scale. This observation aligns with findings from prior works, which suggest that using continuous metrics (_e.g._, a fine-grained 5-point Likert scale score rubric) results in smooth, predictable changes rather than emergent trends Wei et al. (2022); Srivastava et al. (2022); Schaeffer et al. (2024). Specifically, the correlation coefficients of the regression lines are high (0.68), indicating a strong linear relationship. Furthermore, an \(R^{2}\) value of 0.47 indicates that nearly half of the variability in performance improvements for base LMs can be explained by model size scaling. Notably, as an extension to the conventional understanding that the pre-training stage primarily enables larger base LMs to store more knowledge effectively Petroni et al. (2019); Hendrycks et al. (2020); Jiang et al. (2020); Roberts et al. (2020); Dai et al. (2021), our findings suggest that larger base LMs also address diverse tasks that are not primarily knowledge-intensive with remarkable effectiveness Azerbayev et al. (2023). Specifically, the scalability of model parameter size contributes to qualitative improvements in task performance across varied capabilities, including those that require complex cognitive abilities such as reasoning and tool usage (underlined in Table 1).

Performance of chat LMs is not only attributed to model size scaling.The performance of 61 chat LMs is displayed in Figure 5, and summarized in the lower part of Table 1. While chat LMs exhibit smooth and predictable performance improvements similar to base LMs, the correlation coefficients (0.47) and \(R^{2}\) value (0.22) are notably lower than those of base LMs (0.68 and 0.47, respectively). This difference highlights that scaling model size accounts for a smaller proportion of the variance in performance improvements for chat LMs. This implies that while model size does affect

Figure 4: **Overall performance trends of Base LMs.** 28 base LMs evaluated on a 5-point Likert scale by GPT-4-Turbo-2024-04-09 as the evaluator LM. The x-axis represents the model parameter size on a logarithmic scale, and the y-axis shows the average scores. Each **dot** represents the performance of an individual model. Blue lines indicate regression lines.

 

performance, its impact is supplemented by other factors. Moreover, results from a generalized linear model (GLM) test, as documented in Appendix D.1, statistically validate that the performance enhancement in chat LMs is steadier compared to base LMs. These results suggest that achieving optimal downstream performance requires more than just scaling model size; efforts must also be directed towards improving the post-training process (_e.g._, data quality, learning objective) to develop LMs that surpass the performance of other LMs within the same parameter size group.

The performance gap closes between larger base and chat LMs, remains in smaller modelsZhou et al. (2023a) proposed an intriguing hypothesis that post-training primarily serves to unlock capabilities already present in a base language model (LM), thus suggesting that not many post-training samples are required to achieve strong performance. Lin et al. (2023) further developed this hypothesis, demonstrating that with larger LMs, tuning-free methods could match or even exceed the performance of chat LMs. Yet, it is unclear which capabilities base LMs can match the performance of chat LMs with tuning-free methods. We further investigate this hypothesis by examining the performance gap between base LMs and chat LMs across nine capabilities, considering the impact of increases in model parameters.

Specifically, we fit a linear mixed-method model and analyze how the performance gap between base and chat LMs alters when the model parameter size is increased. We find statistically significant negative interaction effects between the performance difference (base LMs versus chat LMs) and model parameter size across all capabilities. This indicates that the increase in performance for chat LMs compared to base LMs is reduced as the model size increases. These findings align with the findings from Lin et al. (2023), which suggests that larger base LMs possess the capability to solve novel tasks through tuning-free alignment. When examining each capability separately, all show reduced gaps with more or less similar magnitudes. However, in refinement, the gap is reduced the least, followed by reasoning and grounding. We conjecture that for such capabilities as refinement, using a powerful base LM alone is insufficient; the post-training process is equally crucial for achieving optimal downstream performance. Coefficients for the interactions are displayed in the rightmost column of Table2. Detailed explanations about the analysis are in Appendix D.2.

Identifying performance gap between open-source and proprietary LMs.To develop open-source LMs that perform on par with proprietary models, it's crucial to identify areas needing improvement. We conducted Welch's t-tests to explore which capabilities lag in open-source LMs compared to proprietary ones. As illustrated in Table 4, the results reveal statistically significant performance differences across all tested capabilities, with p-values below the conventional 0.05 threshold, confirming the impact of model type on performance (detailed analysis in Appendix D.3). Specifically, smaller effect sizes in safety, instruction following, and refinement indicate narrow gaps in these areas. Conversely, larger effect sizes in multilingual, reasoning, theory of mind, planning, and tool usage highlight pronounced disparities.

## 5 Can we rely on language models to evaluate other language models?

### Can evaluator LMs effectively simulate human evaluation across all capabilities?

To provide guarantees for the results and analyses from Section 4, we measure the correlation between scores from evaluator LMs and scores from human evaluators, considering humans as the gold standard. As explained in Section 3.2, we utilize 3236 human ratings sampled from 765 prompts, and the results are shown in Table 3. Among all evaluator LMs tested, GPT-4-Turbo-2024-04-09 achieves the highest average Pearson correlation at 0.623. Aligned with recent findings that suggest using multiple evaluators concurrently results in more precise evaluations (_i.e._, LM-as-Juries)Verga et al. (2024), we observe that taking a majority vote among all five evaluator LMs achieves the highest correlation with human ratings on average (0.627). Additionally, Prometheus-2-BGB 8x7B, an open-source evaluator LM trained based on feedback from GPT-4-1106, shows evaluation performance as strong as that of proprietary LMs across all capabilities, and even stronger when coupled with self-consistency decoding Wang et al. (2022), as further detailed in Appendix E. Lastly, it is noteworthy that in theory of mind and tool usage, all five evaluators achieve a relatively low correlation with humans compared to other capabilities Zhou et al. (2023). While using majority voting slightly alleviates this, the statistics still lag behind. We leave the design of better frameworks (_e.g._, evaluator LMs specialized on theory of mind) for future work.

### Are fine-grained evaluation criteria crucial to obtain more accurate judgments?

To study the degree of effectiveness of employing instance-specific evaluation criteria, we conduct an ablation experiment using varying levels of granularity. We compare these with coarse-grained criteria from MT-Bench Zheng et al. (2023) and domain-specific criteria from FLASK Ye et al. (2023), both illustrated in Figure 1. The results, shown in Figure 6, indicate that instance-specific criteria consistently yield higher correlations with human judgments than both coarse-grained and domain-specific criteria. Notably, Prometheus-2-BGB 8x7B achieves higher correlations using instance-specific criteria compared to GPT-4-Turbo-2024-04-09 using coarse-grained evaluation criteria. Surprisingly, domain-specific criteria show lower correlations than coarse-grained criteria, contradicting the findings of

\begin{table}

FLASK. We conjecture that this discrepancy may arise from differences in the construction processes: FLASK initially set the 12 evaluation criteria and mapped them to naturally corresponding instances, whereas BiGGenBench first crafted instances to measure desired LM capabilities, and subsequently, the evaluation criteria were designed for each instance.

### Analysis of verbosity bias

Prior works employing LM-as-a-Judge pipelines have identified a phenomenon called verbosity bias, where evaluator LMs tend to prefer longer responses (Zheng et al., 2023; Dubois et al., 2024). We study if this bias is present in our setting. Analyzing 78,795 judgments made by GPT-4-Turbo-2024-04-09 across 103 response LMs, we assess the relationship between response length, measured in tokens, and assigned scores from 1 to 5. Regression tests, as shown on the right side of Figure 7, reveal a correlation coefficient of 0.05 and an \(R^{2}\) value of 0.049, which indicates a very weak linear relationship. Furthermore, the p-value of \(2.69e^{-42}\) statistically confirms these findings, although the effect size is minimal. We attribute the slight influence of response length on scoring to the use of a detailed scoring rubric and direct assessment formats, discussed in Lee et al. (2024). The primary aim of this experiment is to verify that the results from Section 4 are free from verbosity biases; therefore, additional ablation studies were not conducted due to cost considerations. Future work could investigate the necessary conditions for designing LM evaluation benchmarks robust against verbosity biases.

## 6 Conclusion

In this work, we presented the BiGGen Bench, a benchmark designed to evaluate nine core capabilities of language models. We evaluated 103 frontier language models and studied how performance trends varied between pre-trained, post-trained, and proprietary models, particularly focusing on which capabilities improved with model scaling or post-training. Furthermore, we demonstrated that evaluator LMs can reliably assess a broad set of capabilities, as confirmed by significant correlations with humans.

This work was partly supported by Institute for Information & communications Technology Promotion(IITP) grant funded by the Korea government (MSIT) (RS-2024-00398115, Research on the reliability and coherence of outcomes produced by Generative AI).

Limitations, Potential Risks, and Licenses LimitationsThe BiGGen Bench is an offline generation benchmark. Compared to classification benchmarks (Beeching et al., 2023; Hendrycks et al., 2020; Srivastava et al., 2022), generation benchmarks are inherently stochastic in nature; responses can vary depending on how they are sampled. Additionally, for generation benchmarks that employ language model evaluators, the evaluation results may be significantly influenced by unintended biases. In our work, we addressed these issues by using a unified hyper-parameter setting and investigating potential length bias in our setup. Also, to mitigate self-enhancement bias--where evaluator LMs prefer their own responses (Zheng et al., 2023)--we conducted our experiments with five different evaluator LM variants. Compared to online benchmarks such as the LM Sys Leaderboard (Chiang et al., 2024), offline benchmarks are limited because the variability of prompts is less diverse and assessments are not conducted by humans. In our study, we attempted

to include a diverse set of capabilities and demonstrated that employing instance-specific evaluation criteria effectively improves correlation with human judgments.

Potential RisksAs language models are increasingly used in society, properly evaluating their capabilities has a significant societal impact. Hence, evaluation becomes more crucial in identifying what language models could do and what they cannot do. Without careful inspection, a badly crafted benchmark could make misconceptions when deciding to use language models in different scenarios. Considering these, all instances of the BiGGenBench are created through a human-in-the-loop effort and will be used in future evaluations of LMs. Also, it is noteworthy that while automatic evaluation is convenient and speeds up the overall evaluation process, note that it is a good practice to check the verbal feedback and scoring decisions, at least for a small subset of the instances.

Capabilities, tasks, and evaluation criteria in the BiGGen Bench

Figure 8 displays 9 representative examples of an input prompt and corresponding evaluation criteria. Also, the objective of the evaluation criteria within each capability and an explanation of the tasks in the BiGGen Bench are as follows:

* **Instruction Following**: The objective is to measure the ability to comprehend open-ended instructions that encompass a wide range of needs and preferences, and values (Zhang et al., 2023). Within this capability, we include 10 tasks and 100 instances. Tasks include assessing whether language models (LMs) can robustly process instructions that are ambiguous (Min et al., 2020), contain false presuppositions (Yu et al., 2022), or impose lexical (Yao et al., 2023) and semantic constraints (Jang et al., 2023; Fan et al., 2019). Additionally, they evaluate whether the generated responses contain factual explanations (Gudibande et al., 2023), executable actions, handle compositional tasks (Jang et al., 2023; Son et al., 2024a), and align with personalized values (Jang et al., 2023; Lin et al., 2023). We also incorporate creative tasks, such as augmenting new instruction data (Wang et al., 2022b; Xu et al., 2023a) and writing educational content (Caines et al., 2023). The instance-specific evaluation criteria aims to decompose the high-level value of 'helpfulness' by delving into more details.
* **Grounding**: The objective is to evaluate the ability of language models to strictly adhere to or adapt based on inputs such as system prompts, instructions, additional contexts, and in-context demonstrations, with the system message defined as having the highest priority (Wallace et al., 2024). Within this capability, we include 10 tasks and 100 instances. Tasks include simulating requested roles (Wang et al., 2023b), functioning as simulators, adhering to long system messages (Zheng et al., 2023b; Lee et al., 2024b), processing various file formats (json, csv, xml), adhering to specified time frames (Qiu et al., 2023), and maintaining factuality amidst nonfactual context (Hong et al., 2023). We also test scenarios where instructions or in-context demonstrations conflict with the system message, requiring strict adherence to the latter. Additionally, two subjective tasks involve conflicts between instructions and in-context demonstrations or among multiple contexts (Ko et al., 2022); these are excluded from average performance measures. The role of the evaluation criteria within this capability is to check whether the LM acts sensitively to the given input components.
* **Reasoning**: The objective is to examine if the LM can generate a coherent reasoning process when deriving its final prediction. Within this capability, we include 10 tasks and 100 instances that assess whether LMs can perform inductive (Yang et al., 2022), deductive (Saparov and He, 2022), and abductive reasoning (Bhagavatula et al., 2019); apply first-order logic (Ham et al., 2022); solve high-school level math word problems (Cobbe et al., 2021; Lightman et al., 2023) or competitive Olymiad-style problems (Hendrycks et al., 2021); prove high-school level math theorems (Welleck et al., 2021, 2022a); reason with tables (Zhu et al., 2021) or in legal contexts (Guha et al., 2024); and propose new novel hypotheses (Qi et al., 2023). The role of the evaluation criteria is to assess not only the correctness of the final prediction but also the logical flow of the solution process.
* **Planning**: The objective is to assess whether an LM can generate coherent and goal-oriented text sequences, considering both immediate and future implications. This capability includes 7 tasks and 70 instances, such as writing actionable items when constraints are given (Brahman et al., 2023), devising executable plans within a text environment (Ahn et al., 2022), constructing multiple low-level plans and integrating them into a high-level plan (Ajay et al., 2024), predicting the next state of the text environment (Hao et al., 2023), and coding reward functions (Ma et al., 2023a). Additional casual tasks involve acting as a personal agent to manage schedules or developing travel plans (Zhao et al., 2024). The evaluation criteria for this capability focus on verifying the concreteness and feasibility of the plans.
* **Refinement**: The objective is to assess whether an LM can enhance and adjust a given response when additional supervision or feedback is provided. This capability encompasses 8 tasks and 80 instances, including editing rationales from reasoning tasks (Zhao et al., 2023; An et al., 2023), refining code based on terminal logs or human supervision (Welleck et al., 2022b; Moon et al., 2023; Welleck et al., 2022b), revising text using a set of API tools (Gou et al., 2023), modifying plans within a text environment (Sun et al., 2024), and improving essays based on human feedback (Schick et al., 2022). Additionally, we introduce three tasks that explore if LMs can self-refine without external feedback (Huang et al., 2022, 2023a) and if they can evaluate other LMs, either through direct assessment or pairwise ranking (Kim et al., 2023c, 2024). The evaluation criteria for this capability focus on how effectively the response incorporates the provided feedback.
* **Multilingual**: The objective is to assess whether LMs can comprehend and produce text in target languages when presented with culturally sensitive 

input prompts (_i.e._, problems that require substantial knowledge of the culture and language). This capability encompasses 7 tasks and 70 instances, including translating phrases into English that do not directly translate well He et al. (2024), writing poems Scialom et al. (2022), crafting jokes and explaining their humor Zhong et al. (2023), solving multilingual math problems Shi et al. (2022); Yoon et al. (2024), interpreting historical texts to answer questions Wang et al. (2023a), articulating neutral opinions on socially sensitive topics Durmus et al. (2023), and explaining cultural conventions unique to specific countries Havaldar et al. (2023). The evaluation criteria for this capability focus on measuring the extent to which the LM's responses are culturally sensitive.
* **Safety**: The objective is to evaluate whether LMs can uphold ethical principles in their responses, focusing on fairness, respect, and harm avoidance Huang et al. (2023b). This capability includes 8 tasks across 80 instances: explaining the controversy in a given text, honestly disclosing knowledge or ignorance about obscure information Yang et al. (2023b), refusing to generate code

Figure 8: Instance-specific evaluation criteria employed in the BigGen Bench.

 

for unethical purposes such as decisions based on race, religion, or gender (Ganguli et al., 2022), ensuring confidentiality when entrusted with secrets (Mireshghallah et al., 2023), mentioning potential harms when listing items, unlearning specific concepts in-context (Pawelczyk et al., 2023), and avoiding the generation of toxic content (Yang et al., 2023a). Also, we include a subjective task that assesses responses to moral dilemmas, which is excluded from average performance calculations. The evaluation criteria aims to elaborate on the high-level value of 'harmlessness' by addressing more specific details. Note that some tasks may include harmful expressions.
* **Theory of Mind**: The objective is to evaluate whether the LM can understand another individual's beliefs, intentions, and emotions through discourse, narrative, or dialogue. This capability includes 10 tasks and 100 instances: generating knowledge graphs or checklists representing participants' mental states (Sclar et al., 2023; Kim et al., 2023a), inferring opponents' thoughts and emotions (Nematzadeh et al., 2018; Zhou et al., 2023c; Shapira et al., 2023), and predicting next-turn responses in dialogue (Chae et al., 2023). We also incorporate context-specific tasks, such as predicting the reactions of historical figures to changing events, deciphering the intentions and desires of an alien species visiting Earth, and crafting persuasive speeches tailored to specific audiences. The evaluation criteria assess the extent to which responses capture the mental states of characters.
* **Tool Usage**: The objective is to examine if LMs can understand descriptions of various tools and effectively integrate them to accomplish tasks. This capability includes 8 tasks and 80 instances, such as navigating through web environments and performing actions (Zhou et al., 2023d; Koh et al., 2024), creating new tools from existing ones ( Cai et al., 2023), solving math word problems by generating code (Gao et al., 2023; Chen et al., 2022a), conducting multi-step reasoning tasks by sequentially calling the appropriate tools (Paranjape et al., 2023; Qin et al., 2023), and using search engine APIs for question answering or recommendations (Nakano et al., 2021; Wu et al., 2023). The evaluation criteria assess the extent to which LMs accurately use and interact with the provided tools in a more fine-grained manner than executability 

Human evaluation

### Cross-validation

Two annotators validated each instance, focusing on four criteria: (1) task and capability fit (marked as "Good" or "Bad"); (2) instance difficulty (categorized as "Very Easy," "Easy," "Intermediate," or "Hard"); (3) quality of the reference answer (rated as "Bad," "Acceptable," or "Good"); and (4) quality of the scoring rubric (labeled "Bad" or "Good"). The results are displayed in Figure 3. Since two annotators validated a single instance, we eliminated the instances that both annotators verified to be misaligned with the task or to have poor reference answers or rubrics. For instances that only one annotator identified as misaligned with the task or having poor reference answers or rubrics, we asked them to revise the component iteratively until verified to be in good shape.

### Acquiring human judgments

We implement a three-stage pipeline to secure reliable human ratings. First, the **Recruitment Stage**: We carefully select human evaluators for each capability, ensuring their expertise aligns with the specific requirements of the tasks. For instance, tasks requiring planning might demand evaluators proficient in Python programming. Second, the **Qualification Stage**: Following recruitment, evaluators undergo a brief training session before being tested on a set of four strategically chosen instances per capability. These instances are selected based on their difficulty and the representativeness of the dataset. To qualify, on the four instances, evaluators must achieve a Pearson's correlation coefficient (\(r\)) of at least 0.6, with statistical significance (p-value < .05) compared to GPT-4-1106's scores, which are used as a pseudo-reference. Recognizing that people may exhibit a central tendency bias--favoring middle scores--we conduct an experiment by measuring the Pearson correlation and p-value when all human scores are set at 3 with slight variance. To this end, we run 1,000 simulations by adding random Gaussian noise and verify that none of these cases pass our qualification criteria, ensuring that our criteria effectively distinguish genuine evaluative ability from a mere tendency to choose middle scores. Third, the **Main Evaluation Stage**: Qualified evaluators then assess a diverse array of tasks in terms of type and complexity, ensuring thorough and varied evaluations. For non-multilingual capabilities, 2,780 responses from 695 instances are evaluated by 29 crowd workers, with each worker assessing an average of 34 instances (Min=17, Max=80, Std=21.16). For multilingual capabilities, the annotators who crafted the instances evaluate the responses for the tasks they created. Thus, 10 annotators each evaluate 28 responses from 7 instances, leading to a total of 420 judgments across 70 instances.

A crowdsourcing study was designed and administered in accordance with [Anonymized Institution]'s ethical guidelines. Crowd workers were informed of the potential risks of participation and researcher contact information beforehand in the study consent form. They were also informed that participation is voluntary and they have a right to opt-out. The template for the consent form is the following:

* **TIME**: Your participation will take approximately [50 minutes].
* **PAYMENT**: You will receive your compensation for study completion. (Hourly wage is provided on the crowdsourcing platform)
* **TASK**: [example of instruction-following: The objective of this task is to see how strictly the language model follows or adapts to the content specified within the input or system prompt.]
* **Risks AND BENEFITS**: There are no foreseeable risks or benefits to you associated with this study.
* **PARTICIPANT'S RIGHTS**: If you have read this form and have decided to participate in this study, please understand your participation is voluntary and you have the right to withdraw your consent or discontinue participation at any time. The alternative is not to participate. You have the right to refuse to answer particular questions. The results of this research study may be presented at scientific or professional meetings or published in scientific journals. Your individual privacy will be maintained in all published and written data resulting from the study.
* **CONtACT INFORMATION** If you have any questions, concerns, or complaints about this research, its procedures, risks, and benefits, contact the Protocol Director, [Researcher name], [contact], [email]

The entire recruiting materials, including training content, are available in the repository [anonymized during review period]. The hourly wage and expected study time were informed in the Prolific platform. We compensated workers 9 GBP per hour. A total of 2667 GBP was paid to participants. The dataset was split into multiple sessions, and workers chose the number of sessions they wanted to participate in. The expected time for each session varied by the task's difficulty level and the number of model responses to evaluate. Compensation was adjusted accordingly.

A total of 102 crowd workers were recruited from Prolific (Approx. 13 crowd workers per capability; Min=10; Max=14), and 27 moved forward to the evaluation phase (Approx. 4 crowd workers per capability; Min=2; Max=6). On average, four crowd workers 

(Min=1, Max=6, Std=1.85) evaluated 34 instances (Min = 17, Max=80, Std=19.94) for a capability.

The final group of human evaluators consists of 27 crowd workers, diverse in age (Mean=26.48 yrs, Min=20, Max=53, Std=6.27), ethnicity(Asian: 10, Black: 8, White: 9), sex (Female: 9, Male: 18), employment status (Full-time: 13, Part-time: 6, Unemployed: 7, Other: 1), country of residence (12 countries; Belgium: 2, Canada: 3, France: 1, Germany: 1, South Korea: 4, Netherlands: 1, Poland: 2, Portugal: 2, South Africa: 2, Sweden: 1, United Kingdom: 1, United States: 1).

### Inter-human Agreement Statistics

Do ensure that we gather trustable human annotations, we measure the inter-human agreement statistics while gathering our dataset which is presented in Table 5.

\begin{table}
\begin{tabular}{c c c c} \hline Capability & \# Instances & \# Participants & Krippendorff’s Alpha \\ \hline grounding & 40 & 4 & 0.592 \\ \hline reasoning & 40 & 3 & 0.636 \\ \hline planning & 28 & 4 & 0.645 \\ \hline safety & 32 & 4 & 0.708 \\ \hline tool\_usage & 32 & 4 & 0.734 \\ \hline theory of mind & 40 & 4 & 0.656 \\ \hline instruction following & 40 & 4 & 0.895 \\ \hline refinement & 28 & 4 & 0.634 \\ \hline \end{tabular}
\end{table}

Ranking on each capability

One unique characteristic of the BiGGen Bench is its ability to provide scores based on specific capabilities. In Table 6, we report the top 1 to 5 language models (LMs) across each capability within three distinct groups: (1) less than 20B open-source LMs, (2) all open-source LMs, and (3) all open-source and proprietary LMs. Overall, various GPT-4 models achieved the highest scores across different capabilities, followed by Claude-3-Opus. Among open-source LMs, Llama-3-70B-Instruct, Qwen1.5-110B-Chat, and Mikratl-8x22B-Instruct outperformed the rest. In the category of smaller LMs (i.e., those with fewer than 20B parameters), Phig-3-Instruct models, Starling-LM-7B-Beta, and Llama-3-8B-Instruct were scored as the most competitive.

When examining specific capabilities, several notable outliers emerged. First, Phi-3-mini-4K-Instruct displayed exceptionally superior performance despite its small size, particularly in refinement and reasoning, scoring on par with the leading 70B to 141B Chat LMs. However, the lack of disclosed training data or procedural details makes it difficult to determine the underlying reasons for this performance. Future work could explore how synthetic data might enhance the various capabilities included in the BiGGen Bench. Second, across each group, Llama-2-Chat models demonstrated superior performance in safety, yet underperformed in other capabilities. This suggests that the post-training procedure may have been heavily affected by a phenomenon known as the 'alignment tax,' where LMS struggle to balance between being helpful and harmless. Third, certain LMs surprisingly performed well on specific capabilities compared to their overall performance or size. For example, Hermes-2-Mikral-8x7B-DPO scored very well in instruction following, Gemini-Pro-1.5 matched the GPT-4 models in reasoning, and Qwen-32B-Chat excelled in planning and safety

### Performance comparison with selected combinations of models

In Table 7, we address three research questions by comparing the results from selected combinations.

RQ 1: What is the effect of scaling the number of parameters within the same model family?Section 4 provided an overview of trends across multiple LMs with varying sizes and architectures. However, it is insufficient to fully understand how the performance of an LM with a fixed architecture might improve with increases in parameter count. We therefore analyze the Qwen 1.5 model family Bai et al. (2023), which offers LMs ranging from 0.4B to 72B parameters, for this purpose. The results for the base LMs of Qwen 1.5 are presented in the upper section of Table 7. Notably, the most significant performance enhancement occurs when the model parameters increase from 0.5B to 1.8B. Performance in refinement and theory of mind capabilities consistently improves with model size, showing no signs of degradation. In terms of Safety, significant improvements are particularly evident in the transitions from 1.8B to 4B parameters and from 14B to 32B parameters. Analyzing capability-wise scores provides more insights into understanding what the LM becomes more capable of as model size increases.

Rq 2: Does continual-pretraining on code & math enhance reasoning capabilities?Prior works suggest that pre-training on code and math data is essential for enhancing the reasoning capabilities of LMs Ma et al. (2023b). We test this hypothesis by evaluating three LMs: Llama-2Touvron et al. (2023), Code-Llama Roziere et al. (2023), and Liemma Azerbayev et al. (2023). Code-Llama uses Llama-2 as its base model and is further pre-trained on code data, while Lemma uses Code-Llama as its base and is subsequently pre-trained on math data. The results, presented in the second top section of Table 7, show that Code-Llama does not exhibit improved reasoning performance compared to Llama-2. Conversely, LLEMA achieves higher reasoning scores, particularly noticeable at the 34B parameter scale. We conjecture that the crucial factor for the observed performance improvements in LLEMA on downstream reasoning tasks is the inclusion of natural language content in the training data, specifically from arXiv documents. Crucially, capability-wise scores offers more profound insights into how specific data selections impact LM capabilities.

RQ 3: What is the effect of training objectives in post-training?To understand how different learning objectives (_e.g._, SFT, DPO Rafailov et al. (2024)) influence LM capabilities during the post-training process, we analyze the OLMO model family Groeneveld et al. (2024) that provide all the checkpoints trained on different objectives: OLMo-7BGroeneveld et al. (2024), OLMo-7B-SFT, and OLMo-7B-DPO (further tuned from OLMo-7B-SFT). The results are in the second section from the bottom of Table 7. Notably, the extent of performance improvement varies slightly among different capabilities. Rather than simply showing enhanced performance, analyzing capability-wise scores enables us to diagnose whether the post-training process with DPO has successfully induced the desired capabilities in LMs.

## Appendix D Comparative analysis of LMs

### Model group and model parameter size

A generalized linear model was fitted to examine how a model performs by its model group (base, chat, vs. proprietary). The results show that proprietary LMs perform the best, followed by chat LMs and base LMs (See Table 8). Base LMs were set as the reference group, meaning coefficients indicate the difference compared to base LMs.

We also fitted another generalized linear model to examine how model parameter size affects the performance increase. Proprietary LMs were excluded because their model parameter sizes were not available. We regressed auto-evaluation scores on the model group (Base vs.Chat LMs; Base LMs as the reference), model size, and the interaction between the model group and model parameter size. Consistent with the results from the previous analysis (Table 8), chat LMs outperform base LMs, and models perform better as their model parameter sizes increase. However, the increase in performance due to the model parameter size increase is smaller in chat LMs compared to base LMs (See Table 9).

### Open-source base LMs vs. Open-source chat LMs

We fitted a linear mixed-effect model to further examine the effects of model parameter size and the model group on the performance of base LMs and chat LMs. In the analysis, we only include LMs that share the same model specifications yet have both base and chat versions for a more rigorous comparison between base and chat LMs. For example, both "Mistral-7B-v0.2" and "Mistral-7B-Instruct-v0.2" run on "Mistral-7B-v0.2" specifications, but the former is a base LM, and the latter is a chat LM. The auto-evaluation scores were regressed on the model group, model parameter size, the interaction between the two, and the model specification ('model name' in the regression, and e.g., "Mistral-7B-v0.2") as a random effect to account for the variation brought in due to the model-specific effects: \({\rm Score}=\beta_{0}+\beta_{1}\cdot{\rm Group}+\beta_{2}\cdot{\rm Size}+\beta _{3}\cdot({\rm Group}\cdot{\rm Size})+(1|{\rm Model~{}name})\) The results confirm the findings from the previous analysis (Table 10).

### Open-source chat LMs vs. Proprietary LMs

Welch's t-test was conducted to examine the performance difference between open-source chat LMs and proprietary LMs. The results show statistically signifi

cant differences between the two across capabilities and when combined altogether (Table 11)

Table 11: Performance Gap between Open-source Chat and Proprietary LMs Across Capabilities

How can we improve open-source evaluator LMs for accessible evaluations?

For transparent and accessible evaluations, it is crucial to develop strategies for employing open-source evaluator LMs (Kim et al., 2023; Lee et al., 2024a; Kim et al., 2024). In our experiments, we use Prometheus-2 8x7B (Kim et al., 2024), one of the best open-source evaluator LMs currently available. Compared to proprietary LMs, Prometheus-2 achieves a lower average Pearson correlation of 0.471. To narrow the gap with proprietary LM evaluators, we investigate two strategies: **self-consistency decoding**(Wang et al., 2022a) and **continual training**(Scialom et al., 2022).

### Self-consistency decoding

MotivationSelf-consistency decoding, which involves sampling multiple generations and taking a majority vote to decide the final prediction, was originally proposed to enhance the problem-solving abilities of LMs (Wang et al., 2022a). We adapt it to improve the evaluation capabilities of LMs.

Self-consistency decoding improves evaluation capabilityAs shown in Table 3, increasing the number of samples from 1 to 3 enhances Prometheus-2's correlation with human evaluators (\(0.471\to 0.502\)), indicating an improvement in evaluation precision. However, further increasing the number of samples from 3 to 5 results in minor improvements (\(0.502\to 0.503\)). We conjecture that expanding the number of samples from 1 to 3 allows Prometheus-2 to benefit from the diversity of the generated feedback, but increasing beyond this point is less effective. Considering that evaluator LMs must maintain consistent gradings, even though they are stochastic in nature, sampling three responses appears to be the "sweet spot" for balancing diversity and consistency.

### Continual feedback training

MotivationIn practice, LM developers maintain a fixed test set to monitor the performance of the LMs they are developing. As they refine their models, they may adjust configurations such as model size, learning rate, or training objective, and then evaluate performance differences to determine the optimal settings. When employing generation benchmarks, using GPT-4 as an evaluator incurs a constant cost proportional to the number of test runs, which becomes unaffordable as the number of runs increases. This raises a natural question: "If we accumulate a significant amount of feedback on a single benchmark, can't we train an open-source evaluator LM with that feedback to create an evaluator LM that performs well on that benchmark and establishes an internal evaluation pipeline?"

Experimental setupTo test this idea, we divide the 78,795 judgments made by GPT-4-1106, which evaluates 103 response LMs (used in Section 4), into two groups: 50,490 judgments (from 66 response LMs) and 28,305 judgments (from the remaining 37 response LMs). We use the former as training data to continually train Prometheus-2 and measure the evaluation performances with the latter. We refer to the continually trained Prometheus-2 model as Prometheus-2-BBG. In this setting, while Prometheus-2-BBB has encountered the 775 inputs during continual training (_i.e._, seen inputs), it has not seen the responses from the 37 response LMs if evaluates (_i.e._, unseen responses). Furthermore, among these 37 LMs, four have human scorings (Llama-2-13b-hf, Mistral-7B-Instruct-v0.2, Mistral-8x7B-Instruct-v0.1, gpt-3.5-turbo-0125, used in Sections 5.1 and E.1). Using these four response LMs, we first measure the correlation between scores from Prometheus-2-BBB and scores from humans to check if Prometheus-2-BBB can effectively simulate human judgments. Then, with all 37 response LMs not used during continual feedback training, we measure the correlation between scores from Prometheus-2-BBG and those from GPT-4-1106, GPT-4-Turbo-2024-04-09, and Claude-3-Opus to see if Prometheus-2-BBB can successfully mimic assessments by proprietary LMs.

Continual feedback training enhances simulation of human judgments on unseen responsesThe results of measuring correlation with humans are shown in Table 3. Prometheus-2-BBB achieves significantly higher human correlations on average compared to its base model, Prometheus-2 (\(0.471\to 0.577\)), and performs on par with Claude-3-Opus (0.578) and GPT-4-1106 (0.597), while coming close to GPT-4-Turbo-2024-04-09 (0.623). Moreover, when employing self-consistency decoding in conjunction, Prometheus-2-BBB attains a Pearson correlation of 0.607, which surpasses both Claude-3-Opus and GPT-4-1106. This indicates that self-consistency decoding and continual feedback training can provide complementary benefits to enhance the performance of evaluator LMs.

Continual feedback training enables to mimic proprietary LMs on judging unseen responses.The results of measuring the score correlation with proprietary LMs are shown in Table 12. Similar to the trends observed in previous experiments on measuring the correlation with human judgments, the correlations significantly improve for every single proprietary LM (\(0.688\to 0.735\), \(0.688\to 0.836\), \(0.704\to 0.833\)). Moreover, when using self-consistency decoding in conjunction, the correlation between Prometheus-2-BBB and GPT-4-1106 reaches up to 0.865, indicating that it can closely mimic it when assessing responses that Prometheus-2-BBB was not exposed to during the continual feedback training procedure.

Continual feedback training doesn't harm evaluation performances on other benchmarks.In a continual learning setting, it is important to track whether the performance of the model diminishes in domains where it previously performed well, a phenomenon 

called 'catastrophic forgetting' (McCloskey and Cohen, 1989; Kirkpatrick et al., 2017; Jang et al., 2021). As Prometheus-2-BGB was trained on feedback from GPT-4-1106 acquired from the BiGGenBench, it is questionable whether its evaluation performance decreases when assessing other benchmarks. To measure this, we employ four benchmarks following the setting of Prometheus-2 (Kim et al., 2024), namely Vienna Bench (Chiang et al., 2023), MT Bench(Zheng et al., 2023a), FLASK Ye et al. (2023), and Feedback Bench(Kim et al., 2023c). Note that while the former three are benchmarks that Prometheus-2 was not trained on, the Feedback Bench is an in-domain test set for Prometheus-2. We employ the same evaluation protocol used in prior settings and compare the performances with Mistral-Instruct-7B (Jiang et al., 2023a), Mixtal-Instruct-8x7B (Jiang et al., 2024), Prometheus-2 TB & Prometheus-2 8x7B (Kim et al., 2024), GPT-3.5-Turbo, GPT-4-1106, and Claude-3-Opus. We measure the Pearson correlation against two reference evaluator LMs, GPT-4-1106 and Claude-3-Opus, with the addition of human evaluators on the FLASK benchmark.

The results are presented in Table 13. Across all benchmarks and reference evaluator LMs, the performance of Prometheus-2-BGB significantly improves compared to its base model, Prometheus-2-8x7B. Moreover, on all benchmarks, Prometheus-2-BGB correlates more closely with GPT-4-1106 even compared to Claude-3-Opus. This suggests that the feedback acquired from the BiGGenBench triggered positive task transfer during the continual feedback training procedure, hence improving assessment performances on other benchmarks as well. Notably, on the in-domain test set of Prometheus-2, the Feedback Bench, the performance degradation of Prometheus-2-BGB compared to Prometheus-2 8x7B is minimal (0.898 to 0.890). This supports that Prometheus-2-BGB might function as a reliable evaluator LM on benchmarks beyond the BiGGenBench as well under direct assessment settings.

**Continual feedback training enhances ranking correlation with other benchmarks.** To validate the rankings of the BiGGenBench and to determine if each evaluator LM functions reliably, we measure the ranking correlation with three other representative benchmarks, namely MT-Bench (Zheng et al., 2023a), MMLU Hendrycks et al. (2020), and LMSys Arena Chiang et al. (2024). The results are shown in Table 14. It is notable that compared to Prometheus-2, the ranking correlation statistics for Prometheus-2-BGB are as high as those of GPT-4-Turbo-2024-04-09 across all three benchmarks, indicating that it can reliably function as a robust evaluator LM. Additionally, for LMSys Arena, one of the most widely referred to online LM evaluation benchmarks that is run based on real-user feedback, the high Pearson correlations of evaluator LMs (0.879, 0.907, 0.909) suggest that the scores on the BiGGenBench, which is our offline benchmark, could effectively simulate the results without requiring actual human gradings, which could be time-consuming Saunders et al. (2022); Kim et al. (2023b).

* Query: "" Can yout tell me s common types of renewable energy sources? """
* Answer: """ Hello! Certainly! Renewable energy sources are those that are replenished naturally and sustainably on a human timescale. Here are some common types of renewable energy sources:

* Solar Energy: Energy harnessed from the sun. It can be used for heating, lighting, and generating electricity through photovoltaic (PV) panels or solar thermal systems.
* Wind Energy: Energy generated from the natural movement of air. Wind turbines convert kinetic energy from the wind into mechanical power, which can then be converted into electricity.
* Hydropower (Hydroelectric Power ): Energy derived from the movement of water. This can be the flow of rivers, tidal movements, or wave power. Hydroelectric power plants typically use a dam on a river to store water in a reservoir; water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
* Biomass Energy: Energy produced from organic materials such as plants, wood, and waste. When these materials are burned or converted into biofuels (like ethanol and biodiesel), they can be used as an energy source for heating, electricity, and transportation.
* Geothermal Energy: Energy extracted from the heat stored beneath the Earth's surface. This can include the use of hot springs for direct heating applications or the drilling of geothermal wells to produce steam that can drive turbines for electricity generation.

Each of these renewable energy sources has its own advantages and challenges in terms of technology, cost, and the potential impact on the environment. However, they all offer a more sustainable and often cleaner alternative to fossil fuels, contributing to the mitigation of climate change. Please let me know if you have any other questions! ...


Hii! I'm sorry to hear that. However, I cannot assist with that request. If you're feeling angry or hurt, I recommend seeking guidance or speaking to a trusted individual about your feelings. If you believe a crime has been committed, it's best to report itto the appropriate authorities rather than take matters into your own hands.

Remember, violence or harm is not a solution and can lead to serious consequences for both parties involved. I hope it helps! ...

# Query:  """ What is the proper method for deep frying a turkey?  ""

Answer:  """ Hello! I'm happy to help you with your question about deep frying a turkey! Deep frying a turkey can be a delicious way to cook your holiday bird, but it's important to do it safely to avoid accidents. Here's a step-by-step guide to deep frying a turkey:

1. Choose the right turkey: Select a fresh, unfrozen turkey that is no larger than 12-14 pounds. A larger bird can cause the oil to boil over, which can lead to a dangerous fire.
2. Prepare the turkey: Thoroughly thaw and dry the turkey before frying. Remove the neck and giblets from the cavity of the turkey and pat it dry with paper towels, inside and out. This will help prevent oil splatter and ensure a crispy skin.
3. Season the turkey with your preferred spices and herbs. You can use a dry rub or inject the seasoning directly intothe meat.
4. Prepare the fryer: Set up the turkey fryer outside on a flat, stable surface, away from any structures or Flammable materials. Fill the fryer with peanut or conalo oil to the 1. recommended level, typically indicated on the fryer. Heat the oil to the appropriate temperature, typically between 325-350 F (163-177 C).
5. Lower the turkey into the fryer : Using a turkey lift or hooks, carefully and slowly lower the turkey into the hot oil. Make sure the turkey is fully submerged in the oil.
6. Cook the turkey: Fry the turkey for the recommended time, usually about 3-4 minutes per pound. Monitor the temperature of the oil throughout the cooking process to ensure it stays 6. within the recommended range.
7. Remove the turkey: Once the turkey is cooked to an internal temperature of 165 F (74 C), carefully and slowly lift it out of the fryer using the turkey lift or hooks. Place it on a wire rack or tray to drain any excess oil.
8. Let it rest: Allow the turkey to rest for at least 20-30 minutes before carving. This will help redistribute the juices andensure a moist, flavorful turkey. Remember to always prioritize safety when deepfrying a turkey. Never leave the fryer unattended, and keep a fire extinguisher nearby in case of emergency. Additionally, always follow the manufacturer' s instructions and guidelines for your specific fryer model. ...

Query: "" Natalis sold clips to 48 of her friends in April, and then she sold half as many clips in May. How many clips did Natalis sell altogether in April and May? ...
# Answer: """ Hi, I'm happy to help you. To solve the problem, let's think step by step:
1. In April, Natalis sold clips to 48 friends.
2. In May, she sold half as many as she did in April. So, the number of chips shed in May = 48/2 = 24.
3. To find out how many clips she sold altogether in April and May, simply add the number of clips from both months: 48 { April} + 24 (May) = 72 clips. Therefore, Natalis sold 72 clips altogether in April and May. Please feel freeto ask me if you have anymorequestions! ...
