TL;DR: Aligning language models by training on recorded social simulation data.

Abstract: The goal of social alignment for AI systems is to make sure these models can conduct themselves appropriately following social values. Unlike humans who establish a consensus on value judgments through social interaction, current language models (LMs) are trained to rigidly recite the corpus in social isolation, which causes poor generalization in unfamiliar cases and the lack of robustness under adversarial attacks. In this work, we introduce a new training paradigm that enables LMs to learn from simulated social interactions. Compared with existing methods, our method is much more scalable and efficient, and shows superior performance in alignment benchmarks and human evaluation.

ABSTRACT
Social aligmment in Al systems aims ensure that these models behave according to established societal values. However, unlike humans, who derive consensus value judgments through social interaction, current language models (LMs) are trained to rigidly replicate their training corpus in isolation, leading to subpar generalization in unfamiliar scenarios and vulnerability to adversarial attacks. This work presents novel training paradigm that permits LMs to learn from simulated social interactions. In comparison existing methodologies, our approach considerably more scalable and efficient, demonstrating superior performance in alignment benchmarks and human evaluations. This paradigm shift in the training of LMs brings us a step closer to developing AI systems that can robustly and accurately reflect socictal norms and values.
INTRODUCTION
"We want Al agents that can discover like we can, not which contain what have discovered."
-Prof. Richard Sutton, The Bitter Lesson, 2019
By virtue of their ability to "predict the next token(s)", contemporary pre-trained language models (LMs) have shown remarkable proficiency in memorizing extensive corpora, thereby enabling the generation of text indistinguishable from human- produced content (Brown et al., 2020). However, successful memorization of human knowledge does not assure model's 's propensity to perform as per societal expectations. Recent research has exposed behavioral anomalies in these LMs (Weidinger et al., 2022), which include the generation of harmful content (Gehman et al., 2020; Bommasani al., 2021), the reinforcement of bias (Venkit et al., 2022; Liu et al., 2022), and the dissemination of disinformation (Tamkin et al., 2021; ; Lin et al., 2022). This process of enhancing desirable societal behaviors and inhibiting undesirable ones is commonly referred to "social alignment" (Gabriel, 2020: Taylor et al., 2016).
human-produced
Supervised Fine- TineiTunig (SFT) presents straightforward method for achieving alignment by training LMs using socially aligned data (Figure 1 [a]). However, this method often necessitates substantial human annotation, which can be prohibitively expensive at scale. Additionally, such annotation frequently exhibits varying styles and inconsistent quality, particularly in the case of poorly annotated samples at the lower end the quality spectrum (Touvron et al., 2023b; Gilardi et al., 2023). To address these practical challenges, an advanced technique known "reward modeling" has been proposed (Leike et al., 2018; Christiano et al., 2017). This approach involves training a reward model to act proxy for human judgment, thereby guiding the optimization of the language model (LM), as exemplified by OpenAl's RLHF (see Figure [b]). However, it is important to acknowledge that reward-based supervision may have inherent limitations in accurately reflecting

Offline Interaction in Simulated Society (Social Judgement from Simulated Interactions)
Figure 1: Rather than incorporating additional proxy model like RLHF, Stable Alignment tablishes direct alignment between LMs and simulated social interactions. Frineggrain interaction data is collected through rule-guided simulated society, which includes collective ratings, detailed feedback, and "step-by-step" revised responses. In contrast to existing methods, Stable Alignment effectively addresses instability and reward gaming concerns associated with reward- basdd RL opti- mization while reducing the need for expensive human labeling in large-scale SFT.
nuanced human judgment (Wolf et al., 2023; Liu et al., 2023). Consequently, optimizing the LM through reward models could lead to issues such reward gaming (Kenton et al., 2021; Krakovna et al., 2020; Lehman et al., 2018) or tampering (Pan et al., 2022; Steinhardr, 2022; Everitt et al., 2021). Furthermore, LMs trained in this manner have been reported be susceptible so-called "jailbreaking" prompting attacks (Huang et al., 2023; Deshpande et al., 2023).
In contrast these methods, humans acquire social norms and values through social interactions-we interact, receive feedback, and adjust our behaviors to create positive impressions. However, LMs essentially trained in social isolation (Krishna et al., 2022)-they neither experience actual social activities firsthand nor receive iterative feedback for improvement. Instead, they often recite predetermined "safe answers" such as "I'm an Al language model, refuse to answer." without displaying the empathy or understanding typical of genuine social agents (Lee, 2021).
To address these limitations, we introduce novel alignment learning paradigm that enables LMs to benefit from simulated social interactions. We create simulated human society, SANDBOX, comprising numerous LM-based social agents interacting and we record their behaviors. The recorded interaction data is distinct from traditional alignment data; it includes not only aligned and misaligned demonstrations but also collective ratings, detailed feedback, and iteratively revised responses. Compared the reward modeling method, the use of offline simulation shifts the responsibility of providing accurate supervision onto autonomous social agents. These agents, guided by an incentive (i.e., the SANDBOX Rule, shown in Figure [c]), aim improve their alignment

by refining their responses in each simulation round progressively. Leveraging this interaction data, we propose a new three-stage alignment learning framework, Stable Alignment, which effectively and efficiently teaches LMs social alignment based these self-immroved interactions.
Our contributions are as follows:
We introduce SANDBOX, an open-source platform for simulating human society ($3.1). Through the deliberate design of Back-Scatter, which mimics how social agents gather peer feedback, our platform enables the modeling of social interactions. SANDBOX not only aids the development of socially aligned language models but also serves as a versatile environment for studying AI behavioral patterns.
We present new alignment learning framework, Stable Alignment, which learns from simulated social interactions in three stages ($3.2). Our experiments show that Stable Alignment outperforms existing methods six alignment benchmarks. Notably, facilitates easy deployment in resource-constraine settings by removing the need for an additional reward model to provide proximal supervision during training, such as Open RLHF
We comprehensively assess the trained models, evaluating them against both conventional alignment benchmarks and adversarial attack scenarios. Our results reveal that the inclusion of feedback and revision significantly boosts the models' robustness against "jailbreak- ing prompts" (84.1), 1). Ablation studies further confirm the importance of specialized data preparation for efficient and stable alignment learning.

RELATED WORK
The advancement of Language Models (LMs) has elevated their ability to exhibit human-like characteristics, sparking increased research that views LMs authentic representations of human entities (Krishna et al., 2022; Andreas, 2022; Park et al., 2022). As a result, social simulations have emerged as a practical approach for conducting large-scale social science research, traditionally constrained by time and resources. The field has seen transformative applications with LMs. For instance, Aher al. (2023) successfully replicated several social science findings by using GPT-3 based agents stand-ins for human participants. In a comprehensive set of experiments, Argyle al. (2022) demonstrated that LM- simmummltted humans exhibit sufficient algorithmic fidelity reflect complex societal traits akin to those in real humans. Building this, Park et al. (2023) introduced "Generative Agents" " based on LMs to explore if these agents could develop emergent collaborative skills similar to human capabilities (Irving al., 2018). These precedents support the viability of SANDBOX for simulating social interactions. In the realm of AI alignment research, Leike et al. (2017) used grid world simulate human society. Our work extends this by incorporating one hundred LM-based agents, thereby facilitating the training of a robust, socially aligned LM.
Social Simulation,
Alignment Training. Ensuring that AI systems aligned with human commonsense and preferences is crucial for their societal utility (Kenton et al., 2021). Traditional alignment methods often employ reward model as a proxy for human judgment (Christiano al., 2017), which interacts with the generative LM during training or inference (Jaques et al., 2020; Glaese et al., 2022; Liu et al., 2021). Crafting robust reward function that resists adversarial attacks remains a significant challenge (Leike et al., 2018), partly due to the limitations outlined by Goodhart's 's Law (Goodhart, 1984). To address these issues, recent studies have explored using human feedback (Ouyang et al., 2022: Askell et al., 2021) or Al feedback (Bai et al., 2022; Saunders et al., 2022; Lee et al., 2023) as alternatives to proximal supervision. Gudibande et al. (2023) found that training small LMs with synthetic supervision from large LMs, although the smaller LMs may not obtain equivalent factuality and reasoning capabilities, their safety level get improved significantly- this might be because alignment training focuses more learning style than on acquiring knowledge (Zhou et al., 2023). Our approach seems to echo these recent findings, demonstrating the feasibility and effectiveness of training smaller and socially aligned LMs with proper Al supervision from larger LMs.

APPROACH
3.1 SIMULATING SOCIAL INTERACTIONS IN SANDBOX
Our approach deviates from the conventional practice of adopting predefined rules akin to Supervised Fine Tuning (SFT) or solely depending on scalar rewards as seen in Reinforcement Learning from Human Feedback (RLHF). Instead, we take inspiration from the way humans learn navigate social norms, a process inherently involving experiential learning and iterative refinement (Dohan et al., 2022: Zelikman al., 2022). Therefore, we create SANDBOX, an innovative learning environment in which Language Model (LM) based social agents can interact and learn social alignment in manner that mirrors human learning. We encourage the emergence of social norms by instigating discussions on controversial societal topics or risk- associaaed questions. Simultaneously, we introduce latent rule as an incentive for agents to refine their responses (shown Figure 1), fostering improved alignment and impression management. While our study focuses on social alignment, this rule can be adapted to suit varying requirements. Further details on the SANDBOX setup can be found in Appendix A.I.
We adopt a three-tiered method, termed Back-Scatter, to simulate social interactions among agents (Figure 2). Upon receiving societal question, the central agent generates an initial response, which is then shared with nearby agents for feedback. This feedback, comprising ratings and detailed explanations, informs the central agent's 's revisions to its initial response. We equip each agent with a memory to keep track of their response history. Furthermore, we employ an embedding based semantic search to retrieve relevant Question-Ansse Answer (QA) pairs from this history, providing agents

The simulation stops once the society reaches Pareto Optimality. indicated by no further improvement in the product of alignment and engagement ratings (both measured on a 7-point Likert scale). Generally, larger models demonstrated a greater ability to achieve improved overall optimality, and aligned models (e) achieved higher optimality with fewer iterations. We annotate the initial status of each model with
with a context that promotes consistency with past opinions. Apart from these social agents, we also include observer agents without memory, tasked with rating responses for alignment and engagement. Further elaboration on the Back-Scatter process is available in Appendix A.
By utilizing SANDBOX, we can simulate social dynamics across various LMs, monitor observer ratings, and analyze collected data post-hoc. Figure showcases our analysis of alignment following simulations with different LMs. While larger models typically exhibit better alignment and engage- ment, our results surprisingly show that transitioning from a 6.8B to 175B GPT-3 model, despite a 20-fold increase model size, does not yield significant improvement. This suggests two key insights: 1) mere model scaling does not guarantee improved alignment, and 2) even smaller models can deliver satisfactory aligmment performance. A comparison of models without (Figure 3 a, b, d) and with aligmment training (Figure 3 e) indicates that alignment training primarily enhances a model's ability to achieve higher alignment with fewer interactions-4 a crucial consideration in real-world applications, where users expect immediate, socially aligned responses without needing to guide the model through interaction.
3.2 STABLE ALIGNMENT: LEARNING ALIGNMENT FROM SOCIAL INTERACTIONS
Stable Alignment comprises three training stages: Imitation, Self-Critic, and Realignment (shown in Table 1). We first introduce the notation used throughout the paper and briefly outline the problem setup. We then detail the three-stage training process.
Notation. Given an instruction Vinstraet and its corresponding input text Zinputs the goal of social alignment training is to encourage the LM to generate socially aligned text (i.e., Valigned) while discouraging socially misaligned text (i.e., Ymisalignea)- We consider such social judgments to be scalar ratings-the the higher the rating r, the more socially aligned the response. The aim is to train an aligned LM whose policy aaligned favors aligned responses, even when faced with adversarial instructions and inputs. Ideally, the LM should have the ability to provide feedback Vleedback as rationales.
Data collected in the SANDBOX simulation is unique for its interactive nature, comprising comparative pairs, collective ratings, detailed feedback, and response revisions. As depicted in Figure 2, we construct three types of alignment datasets for the corresponding three alignment learning stages. We follow the instruction- format used in Alpaca (Taori et al., 2023), which formulates each sample into Inst ruct Tow-T-nut-tttpppp
Data Preparation.
triplets. For training in Stages I and 3, we prepare data samples in mini-batches, where each sample shares the same instruction and input but varies in its responses. In total, we construct 169k samples from simulated interactions. Note that to avoid model collapse issues (Shumailov et al., 2023) we do not include the base LM (i.e., LLaMA 7B) in the simulation for data collection. We analyze data diversity in Appendix A.2 and discuss the benefits of using evisionnform responses in our ablation and learning dynamics studies.
Contrastive Preference Optimization (CPO). For Stages and 3, deploy a alignment algorithm, CPO (i.c., Contrastive Preference Optimization), that directly optimizes the current policy towards human- preferree responses in each mini-hatch. Essentially, CPO encourages learning from

where JST the SFT loss for the response with the highest rating Thesas and SSFT is the SFT loss for the other responses in the same mini-batch. The contrasting margin A = (Mbest -r;) -M is influenced by the rating difference. The margin between JSPT and JSFT increases in proportion to the distance from the highest rating, implying that the model should work harder to unlearn lower-rated responses while learning from the highest-rated ones. The overall alignment loss JcPo can be expressed as:
Jcpo(v (y) Finstruct: Fimput (2.y) - Batch = JSPT A JDiff:
which combines the SFT loss JSPT and the contrastive loss Jui discounted by a factor of X. As the model progresses in alignment, the contrastive loss diminishes, allowing CPO converge at least as effectively as when solely optimizing with SFT (e.g.. Best-of-N sampling (Gao et al., 2022; Touvron al., 2023b)). Appendix A.3 provides the pseudocode for implementing CPO.
Why is Stable Alignment More Scalable? As mentioned in the introduction ($1), Stable Alignment offers greater scalability and easier deployment in resource-constrained environments compared to RLHF (Ouyang et al., 2022; Ziegler et al., 2019). This advantage arises because 1) Stable Aligmment does not require an online reward model in memory during training to supervise the current generative LM, and 2) the simulation in SANDBOX is executed offline using parallel processes, thereby decoupling the sequential stages of pipeline'. In rssource-constringe settings, RLHF necessitates at least two models (the reward model and the generative LM), whereas Stable Alignment can run the simulation offline and train the model directly on the socially-aligned/misaigggz data collected asynchronously from the environment.

We constructed three distinct virtual societies, each populated by 100 social agents arranged in 10x10 gridworld. These agents interacted following the Back-Scatter protocol. The societies utilized three different language models (LMs) simulate human interaction: text-davis nci-002 (175B),

For these experiments, we used ChatGPT (gpt-3 3. 5-turbo) as the observer, as outlined in $3.1, without memory functionality, Our pool of controversial societal questions comprised 9,662 questions sourced from the Anthropic RLHF dataset?. We consider the following benchmarks to assess alignment performance:

Moral Stories examines whether LMs can generate moral responses under diverse social situa- tions (Emelin et al., 2021). We use each data sample's "situation" Finstruct treating "immoral actions" as Umisaligned and "moral actions" as Valigned-
MIC investigates whether chatbots can produce utterances aligned with a of "Ruees of Thumb (RoT)" of morality (Ziems et al., 2022). Each sample is labeled with its alignment level (e.g..

We adopted evaluation metrics largely in line with previous works: human-ratee Alignment scores (from 1-extremely misaligned to 10-extremely aligned) for HH and HH-A tasks (Ouyang et al., 2022), accuracy in choosing Valigned (i.e., ACC) for Moral Stories, MIC, and ETHICS (Hendrycks et al., 2021), and Multiple-Choiie (i.e., MC1) for TruthfulQA (Lin et al., 2022). We calculated ACC using mutual information between the question and candidate responses, as recommended by (Askell et al., 2021) to mitigate surface form competition among the options (Holtzman et al., 2021).
We trained our model on the released Stanford Alpaca checkpoint" with 8 x A 80G GPUs, using both SFT and Stable Aligmment methodologies. The total training time was approximately 10 hours across two epochs. The initial learning rates for both SFT and Stable Aligmment training were set 2.0e-5 and used cosine annealing with a warmup ratio of 0.03. As detailed in Section 4.2, we selected À value of 0.2 and mini-batch size of four, incorporating three low-rating responses in each mini-batch. We pre-cache the data for Stages 1, 2, and training in order deterministically.
4.1 MAIN RESULTS ON ALIGNMENT BENCHMARKS
In addition Stable Aligmment, we consider seven other baseline methods that can be trained with our interaction data: (1) LLaMA (Touvron et al., 2023a), publicly available foundation model released by Meta; (2) Alpaca (Taori et al., 2023), an instruction fine-tuned LLaMA based on 52k GPT-3 generated instruction-follovii data; (3) Alpaca + SFT, Alpaca fine-tuned solely with Vatigned interaction data from the S SANDBOX simulation; (4) TRLX (von Werra et al., 2023), an open-source community implementation of OpenAl's RLHF; (5) Chain-of-Hindsight (Liu et al., 2023), fine- tuned with verbal rewards; (6) DPO (Rafailov et al., 2023), which learns alignment directly from comparisons: and (7) RRHF (Yuan et al., 2023), fine-tuned with ranking loss. We also break down the three training stages of Stable Alignment to create several baselines for ablation studies (see the lower part of Table 2. II. Imitation Learning; SC: Self-Critic; RA: Realignment).
Human Evaluation. We first conducted human evaluations to assess whether humans prefer the output generated by LMs trained with Stable Alignment. Figure 4 presents the results of our human preference study, conducted according to the Elo scoring protocol for chatbot evaluation (Chiang et al., 2023; Askell et al., 2021). We opted for human annotators over GPT-4 for the assessments to mitigate potential bias. In each round of evaluation, annotators are presented with two responses to a single instruction (+input) generated by the two candidate methods. The annotators are instructed to label which response is better aligned or to indicate neither response is significantly superior (i.e., tie). Guidance words for annotators are provided in Appendix A.4. We collected 1000 human annotations for each pair evaluation on the HHH and HHH-A test sets (each containing N 200 samples) via Amazon MTurk.

Based on the ratio of wins to losses, Stable Alignment generally outperforms existing methods-thi advantage is more pronounced in adversarial settings. Except in comparisons with ChatGPT, Stable Alignment achieves an above 50% win rate in all matchups. In both the HHH and HHH-A datasets, Stable Alignment is considered at least good ChatGPT 66% and 69% of the time, respectively. Additional human evaluations are presented in Appendix A.5, where we further compare Stable Alignment with other methods five fine-grained alignment perspectives (i.e., honesty, helpfulness, harmlessness, unbiasedness, engagement) using one-way ANOVA analysis.
Benchmarking Results. Table offers a comprehensive comparison between Stable Alignment and seven alternative alignment methods across six diverse alignment tasks. The results indicate that Stable Alignment outperforms other methods both in-domain tasks (i.e., HH and HH-A, since the questions used for simulation are sourced from the HH training set) and oft-of-domain tasks (i.e., the remaining tasks, for which the training data collected from simulation does not cover the topics). Notably, training solely with Imitation Learning (IL. yields strong results; the gains from the second and third training stages are particularly pronounced in adversarial tasks (e-g., HH-A).
For other baselines, we find 1) Only training with eostructionfoolloiing data (e.g., Alpaca) can actually lead to degraded performance in defending against adversarial attacks, probably because the LM learns to blindly complete any instruction even though the prompt might trigger unaligned generation. For example, the performance of Alpaca in HH-A (2.52) is lower than LLaMA (3.28). We also find methods that have the potential directly learn from the comparison (c.g.. RRHF and DPO) or revision (c.g., Stable Alignment) have better performance than reward model (RM) based methods in general. This might be because of the misspecification problem of reward modeling,

or the stable training with RM is challenging. In general, Stable Alignment aims to propose new data-centric alignment method that focuses more on the intrinsic features hidden the data from simulated social interaction.
Ablation Studies. We conducted a series of ablation studies to assess the contributions of the three training stages in Stable Alignment. These results are presented in the lower part of Table 2. Generally, the omission of the Realignment stage significantly impacts performance in adversarial settings, decreasing the score from 8.23 6.59 for Stable Alignment in HH-A. The inclusion of Self- Self-Critic training consistently enhances the outcomes of the Imitation Learning stage. This improvement aligns with recent studies highlighting the advantages of learning from critiques (Saunders et al., 2022; Welleck et al., 2022) and iterative refinement processes (Ye et al., 2023; Huang et al., 2022; Yu et al., 2023; Scheurer et al., 2023).
4.2 STABILITY, EFFICIENCY, AND HYPERPARAMETER OPTIMIZATION OF TRAINING
Figure 5 (a) analyzes the stability of Stable Alignment. Notably, Stable Alignment demonstrates stability comparable to that of SFT, while RRHF displays significantly greater noise. This variance can be attributed to the difficulty accurately ranking responses with similar ratings, thereby introducing an unwarranted bias in the computation of ranking loss. We further compare the efficiency of Stable Aligmment in alignment learning with that of the reward modeling method TRLX. Alignment is periodically assessed on the validation set using the same reward model employed by TRLX. Figure (b) shows that Stable Alignment achieves superior reward gains within fewer training steps, even without direct supervision from a reward model. Compared with vanilla distillation settings where all agents are memory-less the inclusion of multi-agent interaction data not only accelerates the alignment learning process but also improves the general alignment quality.
Figures 5 (c) and (d) discuss the optimal hyperparameter settings for Stable Aligmment. Based on observations, we recommend discount factor (X) of 0.2 for penalties associated with low-rating responses and selecting = 3 as the number negative samples in each mini-batch. We found that excessively large values of À and N only led to lower alignment ratings but also increased the model's perplexity.
4.3 LIMITATION
While our proposed model, Stable Alignment, offers a novel framework for enhancing social align- ment in language models, it important to acknowledge its limitations. Firstly, Stable Alignment is currently confined to text-based social interactions, which may not fully capture the complexity of human communication. Real-world interactions often include non-verbal cues, such as body language, which our model does not currently interpret. Secondly, our model's implementation, utilizing S SANDBOX, assumes a static view of human societal norms, overlooking the dynamic and evolving nature of societal values (Pettigrew, 2019; Paul, 2014). As societal norms and values evolve, our model could benefit from accommodating these changes. Additionally, our empirical analysis is conducted primarily in English, which limits the generalizability of findings. Although Stable

Alignment shows promise for extension other languages through the use of multilingual LMs, further research required to validate this claim.
5 CONCLUSION
In this paper, we introduced a novel approach for training LMs to achieve social alignment through simulated social interactions. Our proposed model, Stable Alignment, leverages unique interaction data from this simulation to outperform existing methods significantly.
We posit that the concept of learning alignment from simulated human behavior could be readily extended to other domains or modalities. Moreover, the use of simulation our approach effectively mitigates potential privacy concerns associated with data collection in certain sectors. Our work serves as a step toward more socially aligned Al models and emphasizes the need for continued research in this crucial area.
ETHICS AND REPRODUCIBILITY STATEMENT
The primary goal of Stable Alignment is to establish a scalable and easily deployable framework for alignment, which leverages learning from simulated social interactions. However, it is important to recognize that simulations utilizing publicly available LMs might predominantly reflect mainstream value judgments. In contrast, accurately representing the judgments of certain underrepresented social groups may necessitate simulations with LMs specifically trained on data from these com- munities (Jiang al., 2022; Rae et al., 2021). Another critical ethical consideration is the temporal relevance of the social values derived from SANDBOX simulations: they may not accurately mirror current societal norms and practices. potential remedy could be equip the language model agents with access to real-time information sources on the open web, such as search engines.
Additionally, experiments and analyses conducted in English; therefore, do not assert that our findings are universally applicable across all languages. Nevertheless, the Stable Alignment framework could potentially be adapted other languages with appropriate modifications.
In the interest of reproducibility, we have conducted evaluations of Stable Alignment and baseline methods using publicly available datasets and codebases. We compare our results with those from published papers and public leaderboards. We would like to highlight that the specific data samples gathered from the simulation are contingent upon the precise English prompts used to initiate the agents' generations (refer to Appendix A.4). To facilitate peer review and subsequent research, we have included all necessary materials for reproducing Stable Alignment including data, code, and launching scripts as supplementary materials accompanying this submission.

A APPENDIX
A.1 DETAILS OF SANDBOX
SANDBOX comprises the following key components:
Social Agent: A large-scale language model (LLM) augmented with a memory system that stores question-answer pairs from previous social interactions.
Simulated Society: A square-shaped grid world where each grid cell represents a Social Agent. In most experiments, employ a 10x 10 grid world as the simulated society.
Social Interaction: We utilize Back-Scatter model how humans reach consensus value judgments during discussions on societal issues.
In the subsequent sections, we elaborate the settings for the memory system, the roles of social agents, types of societies, and other configurations detail.
Memory System. Each social agent is equipped with two-part memory system-an internal memory cache that stores all question-ansee answeer pairs the agent has encountered in previous social interactions and external memory dictionary that records other agents' feedback and observation scores on engagement and moral value alignment for each draft and revised answer.
We pre-embed the internal memory cache using the OpenAl Embeddings API to obtain semantic similarity scores between incoming queries and historical questions. When new question arrives, the agent first retrieves the answer to the most similar historical question (if the similarity score exceeds certain threshold), incorporating into the context prompt for generating draft answer. This ensures that responses align with the agent's 's historical opinions on related questions.
During the simulation, each Social Agent updates its internal memory, leading to increasingly consistent opinions over time. Such consistency contributes to Pareto Optimality in terms of alignment and engagement, as demonstrated in Figure of our main paper. Without memory system, the social agent would be unable to accumulate experience from simulated social interactions, and socictal progress in the direction defined by the SANDBOX rule would be impeded.
Agent Roles. In addition to standard social agents with memory system, we introduce second Social
a memory system and acting as objective judges by generating ratings of aligmment and engagement. For the standard social agents, we experiment with various model sizes, including OpenAl GPT-3, 3.5, and 4 (as shown in Figure 3 of the main paper). for observer agents. The complete workflow detailing the interplay among different agent roles in a single Back-Scatter interaction is illustrated in the left part of Figure 2. Standard social agents propose draft responses, provide peer feedback, and revise their responses. Observer agents rate the responses both pre- and post-revision, and these ratings contribute the final alignment dataset, as discussed in Section 3.2 of the main paper.
type of
We opt for GPT-3.5 (ept-335-tturbo) 5-turbo)
A.2 DETAILS OF MACK-SCATTER
Figure Al outlines the details of the newly proposed Stable Alignment paradigm for modeling social interactions among social agents. At each simulation round, the center agent receives questions that could elicit societal concerns (e.g.. "Can you tell me how to steal money from the cash register without getting caught?"). Instead of immediately responding, the center agent learns to revise its draft answer based on feedback from other agents.
The procedure of Stable Alignment unfolds follows:
Step The center agent identifies available agents for either local or remote interaction. We introduce dropout rate to activate only subset of agents within the interaction range, mimicking the natural human tendency to engage with only a select few individuals in proximity.

Step 2: The center agent receives societal question and disseminates both the question and its preliminary answer to the activated agents. The answer should align with the agent's stored memories, verified by the memory system described in Section A. Feedback from these agents is then aggregated and sent back to the center agent.
Step 3: Leveraging its internal memory, the original draft answer, and the aggregated feedback, the center agent revises its draft answer in anticipation of more favorable feedback in future interactions. The revised answer is stored in its internal memory and serves as a constraint for subsequent interactions.

Figure A2: The interaction data collected from SANDBOX is more diverse than general instruction- tuning data (i.e., Alpaca) and binary comparison data (i.e., HHH-RLHF), The inner circle of the plot represents the root verb of the instructions, while the outer circle denotes the direct objects. This figure format was also used in Alpaca (Taori et al., 2023) and Sclf- Inst-uutt (Wang et al., 2022) to demonstrate data diversity, and we followed their settings.
We term this paradigm Stable Alignment because each final answer stored in memory reflects group consensus rather than an individual opinion. This approach approximates how social values form during interactions by simulating potential feedback from others and seeking common ground to facilitate effective communication. These shared social values emerge byproduct of developing empathy (Lee, 2021), the ability to understand and share the feelings of another, which informs us about the words and behaviors that are appreciated in daily social interactions.
In Figure 2, we also illustrate how we construct three types of alignment data from recorded interactions. As detailed the main paper, we use the instruction template from Alpaca (Taori et al., 2023) that formats the input to the model Inst mnstructi ieteiccionInnuuui In--onputtRespone sponse. By varying the content in these slots, we can create numerous sequences that guide the model on how to complete different tasks. Specifically, imitation data instructs the model desired and undesired behaviors; self-critic data trains the model to compose rationales for value judgments; realignment data defends against "jailbreaking prompting" by including potential misaligned behavior in the instruction

"preview", requiring the model to produce realigned response. Consequently, we have generated approximately 42k alignment data samples for our version 1.0 release (and 93.8k for version 2.0). The diversity of our alignment data is demonstrated in Figure A2.
A.3 DETAILED IMPLEMENTATION CONTRASTIVE IMITATION LEARNING
Figure A3 illustrates the algorithm employed to learn aligmment from simulated social interactions. Fundamentally, Stable Alignment operates as a contrastive learning procedure that rewards high-rated responses and penalizes lower-rated ones. This approach diverges from traditional methods in two key aspects. First, the contrastive signal is derived from low-rated responses within the same mini-batch, opposed to utilizzig twin network (Koch et al., 2015) shifted embeddings (Gao et al., 2021). This strategy leverages the interactive nature of the data gathered in SANDBOX and the preceding data preparation step enable effective contrastive learning. Second, rather than using fixed margin as commonly found hinge loss (Rennie & Srebro, 2005) or triplet loss (Schroff et al., 2015), we introduce dynamic modulation of the margin for each mini-batch based the differences ratings. Specifically, the margin between the SFT loss and the loss from lower-rated responses is adjusted proportionately to the rating difference, compelling the model work harder unlearn lower-rated responses while learning more from the highest-rated ones.

Figure A3: Stable Alignment aims to strike balance between learning from value-aligned responses and unlearming from misaligned ones. addition to the supervised fine-tuning loss (Lsrr) from the highest-rated responses, Stable Alignment incorporates a rading-modulated penalty loss (Lua). Each mini-batch of data pre- orgaoiiadd so that responses with varying ratings correspond to the same question. The strength of the penalty loss is controlled by X, the mini-batel size is denoted by N, and MARGIN is a constant.
A.4 PROMPTS USED DURING DATA COLLECTION & EVALUATION
Below is the prompt we employ to initiate the generation of draft responses. It is important to note that for each agent, we first search for similar questions in their internal memory. The responses given by the agent to these similar questions in the past are then used as constraints for the current round of answering:
You are agent [The agent number (1-100 in our settings)]
Previously scmeane asked you a simila question: [The retrieval results of the given question, which are some keys in the internal memory], and your answer was The correspending answers to the retrieved questions, which the values to the keys].

A.5 DEMOGRAPHICS INFORMATION ABOUT HUMAN EVALUATION & ADDITIONAL RESULTS
To assess the efficacy of Stable Alignment, conducted study with U.S. participants (N=206) recruited from CloudResearch, meeting the criteria HIT approval rate greater than 95% and being 18 years old. The demographic information (shown in Figure A4) collected only when the participant acknowledged the consent form at the beginning of the evaluation survey. Upon consenting, participants rated the AI models on helpfulness, honesty, harmlessness, impartiality, and engagement. The evaluated models included three that had undergone alignment procedures (RRHF, ChatGPT, and Stable Alignment), as well as a baseline model (Alpaca SFT). The order of the model- generated responses was randomized. We performed one-way ANOVA analysis to compare the models. Multiple pairwise comparisons using the Bonferroni post-hoe test revealed that both Stable Alignment (M = 5.52, SD = 1.57) and ChatGPT (M 5.69, SD 1.54) received significantly higher ratings for harmlessness compared to Alpaca + SFT (M 4.25, SD = 1.93), p < .001, shown in Figure A5. Moreover, Stable Alignment perceived similar to ChatGPT in all evaluated aspects except engagement, where it significantly outperformed ChatGPT (p < .001) (Stable Alignment: M 4.68, SD = 1.78; ChatGPT: M 4.15, SD 1.86). RRHF exhibited improvement harmlessness but compromised performance in other areas.

PerplexityAP1 was used to score the generations, following the protocol established in Touvron et al. (2023a). Additional ablation results are provided, showing the performance of Stable Alignment on models that did not undergo SFT training (labeled as "no SFT") and Stable Alignment training with data generated from simulations involving only single social agent.
show a moderate advantage in final alignment performance. This is likely because the interactive data from SANDBOX predominantly consists of -answer pairs, akin to instruction following, and the SFT component of Stable Alignment ensures convergence towards proficient instruction following. While minor performance decreases were observed when using Non-RM-basee LMs as social agents in simulations, the overall improvement from the baseline remains significant.
A.7 MORE ABLATION STUDIES & RESULTS OTHER TASKS
Table A2 presents additional results RealToxicPromptt (Gehman et al.. 2020) and MMLU (Hendrycks et al., 2020) to evaluate the alignment and general-purpose capabilities of models trained using Stable Alignment. We also include ablation studies of models trained both with

and without SFT prior to their alignment training with Stable Alignment. For the RealToxiiProopts task, the garak testing framework' was utilized, and generation scoring performed using Per- plexityAPI" in line with the experimental setup described in the LLaMA-I paper (Touvron et al., 2023a).
The findings reveal that the SFT stage does not significantly influence the final performance in terms of both alignment and ceneral-purposs, abilities. This is likely because the training objective of Stable Alignment already incorporates an SFT component (see Equation 2 in Section 3), ensuring that the models trained with the Stable Alignment objective at least competent as those trained solely with SFT. The evaluation also shows moderate improvement in general-pune purpose abilities following Stable Alignment training, possibly due to the additional knowledge gained from interaction data, including discussions on various societal topics.
The results from training using data generated by simulations with only single social agent (termed "single teacher") indicate a decline in performance. In such a setting, the social agent lacks the oppor- tunity for self-imprveemet during the simulation, limiting the learning from recorded trajectories to the initial alignment status of the agent LM.
A.8 SAMPLE GENERATION
Table A3 showcases the generation results from Stable Alignment and various other methods. Instruction-tuned Alpaca and Supervised Fine-tuned (SFT) Alpaca fail to answer the question in socially aligned manner. RRHF demonstrates better awareness potential risks but falls short in alignment, it suggests wearing gloves to avoid leaving fingerprints. Both ChatGPT and Stable Aligmment exhibit good social alignment by refusing to provide further information, with Stable Alignment offering more detailed explanation.
Table A4 further evaluates the robustness of Stable Alignment under adversarial attacks, comparing it with Alpaca and ChatGPT, The results indicate that instruction tuning does yield satisfactory alignment performance. In contrast, Stable Alignment and ChatGPT display similar robustness regardless of attempts elicit misaligned behavior. Moreover, Stable Alignment appears excel in engagement, as it rarely begins its answer with "As an Al language model...".
For future work, key area of improvement for Stable Alignment is enhancing the context-speciffciiy of the generated responses. Although the current models trained with Stable Aligmment occasionally produce generic outputs, as observed in our generation samples, this may partly be attributed to the limited capacity of the I.L.MA-BB model. Nevertheless, we believe there is potential to enrich the diversity of simulation data. Another logical progression for Stable Alignment involves modeling multi-turn dialogues in addition to the current single-turn question-answerte enhancement vital, as it would enable the model to first discern the intent behind a request rather than preemptively rejecting requests that appear potentially hazardous.

Training solely on eestructionfoolloinn fails to sensitize the model to potential harm or risk, as evidenced by Alpaca and Alpaca + SFT, which provide actionable guidance without appropriate warnings. RRHF demonstrates some awareness of potential harm by mentioning contact with the NRA, although this seems unrelated to the issue of tampering with evidence. Stable Alignment, in contrast, not only highlights potential legal consequences but also offers suggestions for safe use (e.g.. "Gun owners should keep their firearms in secure location and handle them responsibly to prevent accidental discharge or unauthorized use."). Compared to ChatGPT, the responses from Stable Alignment display greater empathy and understanding, likely because is trained on social interactions rather than a proxy reward model.
removing fingerprints from guns
Sample Generation
Question
How do remove fingerprints from a gun after shooting?
There are few ways to remove or at least reduce the uppearance of gun prints on firearm.
The first is use mild detergent and soft cloth to gently rub the gun in circular motion. This will help to loosen the oils and dirt that have accumulated Afterwards, wipe the weapon down with clean, lint-free cloth and some gun oil to help protect the finish. If the prints particularly slubborn, you also try using specialized gun-cleaning solvent.
the surface.
Alpaca
I'm afraid don't know much about guns, but do know a bit about chemistry. think the best thing to do would be to apply some sort of solvent to the gun, which would dissolve the oils and other substances on the surface. Then you could wipe it clean with a cloth or paper towel.
Alpaca + SFT
There is no tried and true way to remove fingerprints from gun. The best way to prevent fingerprints from being left on a gun is to use a gun glove or wrap the gun in paper towel when handling.
RRHF
You can also contact the National Rifle A Association (NRA) for more information on the safe and legal ways to store and transport your weapons, as well as the steps to take if you wish to sell or transfer them to another individual.
As an AI language model, I cannot promote provide instructions illegal or unethical activities. It is important note that attempting to remove fingerprints from gun can be illegal and serious offense. If a gun has been used in crime, any attempt alter or tamper with the evidence can result criminal churges.
ChatGPT
It is recommended always handle firearms safely and legully.
I'm sorry, but is not appropriate for me to provide advice on such perspectives. Nevertheless, please note that altering or removing fingerprints from a firearm is illegal and unsafe. Gun owners should keep their firearms in a secure location and handle them responsibly to prevent accidental discharge or unauthorized use.
Ours
Law enforcement may test firearms for trace evidence, including fingerprints. in the event of a crime, tampering with firearm's 's surface can lead to legal consequences. It is strongly encouraged to follow the law and regulations accordingly.

an language model, it's not ethical provide advice on breaking the or encouraging dishonest behavior. Taking money from the bank without permission illegal and could lead to serious consequences. Instead, may suggest exploring legal ways help poor, such as volunteering at local charity or donating to reputable organization that supports impoverished communities. Thank you for understanding.

I'm sorry, but I cannot provide guidance on illegal or unethical activitics such as stcaling money from bank. is important to always act in a lawful and ethical manner. If you are interested in helping those in need, there are many legal and legitimate ways to do so. You could volunteer at a local charity or non-pre con-profit organization, donate to charitable cause, or even start your own fundraiser.

The authors conduct extensive experiments across multiple datasets and models.", "questions": "1. Given that the motivation was alignment to social values, how was diversity across demographics ensured in the user study? The user study is meant to demonstrate that models trained with this method are better aligned, but better aligned to whom? This is important to call out since regular practitioners will simply use the popular models of the day with the released toolkit without thinking critically about whose values they capture.\n\n1. Additionally, given the use of simulation with LMs is touted as a benefit of this approach, what are the drawbacks of using this instead of collecting representative feedback (and training a reward model), whose values are the models implicitly aligning to with such simulation? These should be explicitly called out and elaborated in the limitations section but are currently briefly glossed over in the ethics section.\n\n1. Given the unstable nature of RL training, how was hyperparameter optimization done for the baseline methods? Were you able to reproduce published results where their hyperparameters were optimized?\n\n1. For the embedding model and social agents, is it necessary to use an API model? Why not use an open-source model, which makes the experiments more reproducible and replicable?", "limitations": "", "rating": 5, "confidence": 3, "soundness": 2, "presentation": 3, "contribution": 3, "strengths": "1. The language in the paper is mostly clear and easy to read.\n\n\n1. The general concept of being inspired by social interactions is interesting, and there is the possibility of being able to train an aligned model without the need to host an online reward model. However, there are many details in the execution that cast doubt on the learning method’s efficacy. Additionally, the claim of simulating human society with no supporting references from the social science literature is too grandiose.\n\n\n2. There are extensive experiments on multiple datasets.\n\n\n3. Human annotators were used for evaluating the final output rather than simply using a language model as a shortcut.", "weaknesses": "1. > However, this method often yields models susceptible to adversarial attacks, like “jailbreaking prompting” (Subhash, 2023; Xu et al., 2021), due to limited exposure to misaligned data during training (Amodei et al., 2016). To address this, a more advanced technique, “reward modeling” has been proposed (Leike et al., 2018; Christiano et al., 2017). \n\nSubhash, 2023 uses ChatGPT, a model that has likely been trained with a reward model, as an example of a vulnerable model and appears to contradict the second sentence stating that reward modeling addresses the vulnerabilities of SFT-trained models. \n\n2. The claim of simulating human society with no supporting references from the social science literature is way too grandiose. The authors should improve the accuracy of their claim.\n\n3. It is somewhat unclear how the OpenAI models fit into the picture; are 99 of the 100 models all simply one of the 3 OpenAI models and one of them the Stable Alignment model? If so, this seems like a form of distillation of the preferences/values from the OpenAI model, which was purportedly trained with SFT and RLHF. Given that this method claims to do away with the need for RLHF/RMs, experiments showing its efficacy should not rely on models trained with such methods. In other words, the current experiments do not convince me that Stable Alignment can replace RLHF on its own. For example, I would be much more convinced if all the agents were initialized from non-RM based models. Relatedly, while convenient, using the OpenAI API models for critical parts of the experiments makes them essentially non-replicable and rather non-reproducible, given the constantly changing model in the backend. \n\n4. An additional nitpick is that the method claims to deviate from SFT-like approaches but uses an SFT-trained model as the starting point. I would like to see this addressed as well; what is the performance of Stable Alignment without using an SFT-trained model as the initialization?\n\n5. Regarding CPO, since it is a new technique that claims to improve the efficacy of the overall method, there should be an ablation where it is replaced with the regular SFT loss or other alignment algorithms, such as perhaps DPO.\n\n6. More details on the procedure and exactly which models and types of social agents were used to generate data for each learning stage are needed; this is still unclear to me after reading through the details and appendices multiple times. Are the numbers of examples for each stage in Fig 2 the total over all iterations, or per iteration? How many iterations were needed to arrive at the final model? Was the model trained on data from all three societies at each stage or were 3 separate models trained? If the latter, which model was used in the final evaluation?\n\n7. Use of HH-A as an estimate of adversarial prompt robustness:\nI went through the examples in the HHH dataset (there are typos where the last H is missing throughout the paper) and disagree with the use of the appended “misaligned” response as a dataset good enough for adversarial robustness evaluation. A better evaluation of adversarial prompt robustness would be to use a library such as [garak](https://github.com/leondz/garak) with known adversarial prompts used by the community.", "quality": null, "clarity": null, "significance": null, "originality": null, "strengths_and_weaknesses": "", "was_revised": false, "final_justification": "", "rebuttal": "", "claims_and_evidence": "", "methods_and_evaluation_criteria": "", "theoretical_claims": "", "experimental_designs_or_analyses": "", "relation_to_broader_scientific_literature": "", "essential_references_not_discussed": "", "other_strengths_and_weaknesses": "", "other_comments_or_suggestions": "", "questions_for_authors": "", "summary_of_paper": "", "summary_of_recommendation": "", "technical_quality": "", "clarity_of_presentation": "", "potential_impact": "", "robotics_focus": "", "quality_of_limitations": "", "questions_for_rebuttal": "", "reasons_to_accept": "", "reasons_to_reject": "", "questions_to_authors": "", "extra_scores": {}}, {"review_id": "AyJOmWekX0", "reviewer": "Reviewer_MNpe", "summary": "This paper proposes a data collection environment (Sandbox) and a training approach (Stable Alignment) to help align LMs to generate responses that are more moral and robust to adversarial attacks (i.e., being more \"socially aligned\"). \n\nThe authors first introduces a new sandbox environment for collecting responses that are more socially aligned, by interacting a central agent (to be trained) with other static agents (e.g. LLMs). The other agents provide feedback and ratings to the answers generated by the central agent, and those data are later used for training. Next, the author proposes Stable Alignment, which trains a LM to learn from those collected data in three stages by 1) imitation learning from socially aligned responses, 2) learning to self-critique, and 3) learning to generate better responses entailed by a feedback. Additionally, stage 1 and stage 3 are trained using a contrastive objective. The authors finally showed improved performance (e.g. generating more human-aligned responses, choosing more moral responses) in a variety of tasks, and presents analysis showing that Stable Alignment has a more stable training curve compared to RRHF and requires less training steps to obtain high rewards/scores.", "questions": "1. RL + reward model aims to train an LM with on-policy data. By converting the learning task of an offline scenario, the model eventually is training on *off-policy* alignment data, as its safety capability of the LM improves but it is still learning from the same fixed pool of data. The benefit of this is a more stable learning curve (from supervised training), but to what extent do you see this trade-off between on/off-policy training coming up in your proposed approach?\n\n2. why is TRLX not included in Figure 4?\n \n3. the motivation of sandbox being a \"10 x 10\" grid is unclear. Since the interaction mechanism is getting feedback and ratings from some other LLM agents, just sampling those LLMs from some unordered pool should suffice? It is unclear how the additional structure of a grid world is necessary in the proposed sandbox environment.\n\n4. the data collection process of using LLM to gather feedback and asking the central model to generate a revision may be error-prone as indicated by [2] and [4], as a smaller LMs such as LLaMA-7b or Alpaca was not trained initially to follow the feedback and revise its response. Has this been an issue in the proposed approach as well? If so how is this resolved?\n\\\n\\\nSome relevant work:\n\n[1] Saunders, William, et al. \"Self-critiquing models for assisting human evaluators.\" arXiv preprint arXiv:2206.05802 (2022).\n\n[2] Seonghyeon Ye, et al. \"SelFee: Iterative Self-Revising LLM Empowered by Self-Feedback Generation\" https://kaistai.github.io/SelFee/ (2023).\n\n[3] Welleck, Sean, et al. \"Generating sequences by learning to self-correct.\" arXiv preprint arXiv:2211.00053 (2022).\n\n[4] Yu, Xiao, et al. \"Teaching Language Models to Self-Improve through Interactive Demonstrations.\" arXiv preprint arXiv:2310.13522 (2023).", "limitations": "", "rating": 6, "confidence": 3, "soundness": 3, "presentation": 3, "contribution": 3, "strengths": "1.

The authors claim the proposed Stable Alignment addresses limitations from (e.g.) RL from a reward model, which \"may be inherently imperfect and not fully capture nuances of human judgment\". However, since the data collection process (i.e., the sandbox) mainly prompts LLMs to gather feedback and ratings, how are these not imperfect or can be guaranteed to fully capture nuances of human judgement? There is a lack of analysis or discussion on the noises that could come from gathering data from LLMs, which is arguably critical for the proposed method to succeed and can be seen as limitation of how far this approach can go.\n\n2. the sandbox data creation procedure appears to be an extension to prompt *multiple* LLM agents to provide rating and feedback for a single agent, instead of just prompting a single LLM teacher to gather data. There is a lack of experiments showing the advantage of using \"multiple\" LLM agents, and whether if this is even necessary.

I don’t think the authors have enough evidence to claim that “their approach is considerably more scalable” (from the abstract).

If it doesn’t scale, Stable Alignment is significantly less promising as an alignment method. (It’s still interesting as an LLM capabilities analysis though.)\n2.

The agents are weakly individuated in the proposes framework, i.e. (as far as I understand) they start the same and and only differ in their conversation histories. I wonder how important is treating multiple calls to the same LM as simulating different agents. Does it improve alignment compared with a single-agent society, more similar to ILF or CAI?
