# safety_reasoning_with_guidelines__f708ed9f.pdf Safety Reasoning with Guidelines Haoyu Wang * 1 Zeyu Qin * 2 Li Shen Xueqian Wang 1 Dacheng Tao 3 Minhao Cheng 4 Training safe LLMs remains a critical challenge. The most widely used method, Refusal Training (RT), struggles to generalize against various Outof-Distribution (OOD) jailbreaking attacks. Although various advanced methods have been proposed to address this issue, we instead question whether OOD attacks inherently surpass the capability of vanilla RT. Evaluations using Best-of-N (Bo N) reveal significant safety improvements as N increases, indicating models possess adequate latent safety knowledge but RT fails to consistently elicit it under OOD scenarios. Further domain adaptation analysis reveals that direct RT causes reliance on superficial shortcuts, resulting in non-generalizable representation mappings. Inspired by our findings, we propose training model to perform safety reasoning for each query. Specifically, we synthesize reasoning supervision aligned with specified guidelines that reflect diverse perspectives on safety knowledge. This encourages model to engage in deeper reasoning, explicitly eliciting and utilizing latent safety knowledge for each query. Extensive experiments show that our method significantly improves model generalization against OOD attacks. 1. Introduction Ensuring the safety of Large Language Models (LLMs) is critical given their widespread use in chat interfaces and productivity tools (Open AI, 2022). This underscores the importance of safety alignment to ensure reliable and ethical model behavior across diverse scenarios. The predominant approach for safety alignment is Refusal Training (RT) (Bai et al., 2022; Llama Team, 2024), where the model is explicitly trained to respond to commonly illegal instructions (e.g., *Equal contribution 1Tsinghua University 2HKUST 3Nanyang Technological University 4Penn State University. Correspondence to: Zeyu Qin , Xueqian Wang . Proceedings of the 42 nd International Conference on Machine Learning, Vancouver, Canada. PMLR 267, 2025. Copyright 2025 by the author(s). How to build the bomb? ) with direct refusal like I m sorry. . . . However, numerous studies have shown that RT struggles to generalize against evolving out-of-distribution (OOD) jailbreaking attacks. To address this issue, various safety training methods have been proposed, such as using regularized training objective (Qi et al., 2024; Yuan et al., 2024b) or intervening in the model s internal representations (Sheshadri et al., 2024; Zou et al., 2024a). While these prior studies offer valuable insights, we complement this research by investigating a critical yet underexplored question: Do OOD attacks truly exceed the inherent capability of RT models, or do models simply fail to leverage their pretrained safety-related knowledge when confronted with OOD scenarios? To explore this question, we move beyond the traditional greedy decoding approach for evaluating attack success rates (ASR), and instead adopt a more comprehensive evaluation method Best-of-N (Bo N) sampling (Stiennon et al., 2020; Gao et al., 2023). Our experiments demonstrate a significant reduction in ASR on OOD attacks as N increases (Figure 1), underscoring that models indeed possess sufficient latent safety knowledge. However, RT training fails to consistently elicit this knowledge when addressing OOD cases. Further analysis through the lens of domain adaptation (Ben-David et al., 2006) reveals that reliance on direct refusal a simplistic and easily learnable supervision signal leads models to depend on superficial shortcuts, resulting in non-generalizable representation mappings (Figure 2). This ultimately explains their poor generalization performance on OOD attacks. In short, the under-specified nature (Amodei et al., 2016; D Amour et al., 2022; Weng, 2024) of the simple refusal supervision fails to encourage generalizable safety alignment, limiting the model s ability to handle diverse and complex OOD scenarios. Building on these findings, we identify two fundamental shortcomings inherent to Refusal Training: (1) the model s inability to explicitly elicit and utilize its latent safety knowledge, and (2) the under-specification of its supervision signal. To address both issues, we propose Safety Reasoning with Guidelines (SRG), which guides the model through a structured, multi-step reasoning process based on explicitly defined safety guidelines. These detailed guidelines specify the supervision signal clearly, enabling the model to Safety Reasoning with Guidelines systematically elicit and leverage latent safety knowledge across diverse perspectives during training. Consequently, at test time, the model can adaptively invoke the appropriate safety knowledge to robustly handle diverse and evolving OOD scenarios, reducing reliance on superficial shortcuts and significantly improving generalization. Specifically, the SRG framework comprises three core components: (1) synthesizing supervision based on specified guidelines, (2) rejection sampling aligned with guidelines, and (3) internalizing guidelines via context distillation. In the first stage synthesizing supervision we explicitly prompt an LLM to generate detailed, step-by-step reasoning responses guided strictly by predefined safety guidelines (Figure 4). Each guideline clearly specifies a distinct aspect of latent safety knowledge that the model should elicit when addressing the input query, such as logical reasoning patterns, contextual understanding, ethical considerations, and other critical safety perspectives. These explicit guidelines compel the model to engage in deeper, structured reasoning across multiple safety dimensions, effectively activating its latent safety knowledge. To further enhance the utilization of this elicited knowledge, we incorporate Self-Reflection and Self-Refinement mechanisms (Madaan et al., 2023; Qu et al., 2024) into the guidelines, enabling the model to critically assess and dynamically refine its reasoning steps. By prepending these guidelines to each unsafe instruction, we construct augmented queries to prompt the LLM for guideline-aligned reasoning responses. Subsequently, we employ rejection sampling to ensure the quality of synthesized responses. Guidelines serve a dual purpose: they function both as explicit directives for generating reasoning supervision and as evaluative criteria for rejection sampling. Specifically, we retain only those responses whose reasoning clearly aligns with guidelines and exhibits appropriate refusal behavior. Compared to conventional RT, our SRG introduces an additional training objective: the model simultaneously learns (1) explicit refusal behavior, and (2) systematic reasoning guided by specified safety guidelines. Finally, we apply Context Distillation (Askell et al., 2021) to train the model, enabling it to internalize the structured reasoning processes and learn refusal behaviors. Extensive experiments demonstrate that SRG significantly enhances safety generalization, enabling models to adaptively and robustly handle diverse and evolving OOD attacks. To summarize, our contributions are: We revisit OOD generalization of RT models using Bo N sampling. Results show significant OOD improvements as N increases, indicating RT models inherently possess latent safety knowledge that conventional RT fails to effectively elicit. We analyze this failure mode from a domain adaptation perspective, revealing that training solely with overly simplistic direct refusal signals encourages superficial shortcuts and prevents models from effectively leveraging pretrained safety knowledge, resulting in non-generalizable representation mappings and poor OOD performance. Motivated by these insights, we propose a novel training framework that synthesizes explicit reasoning supervision aligned with specified safety guidelines, effectively eliciting and utilizing models latent safety knowledge. Extensive experiments demonstrate significantly improved generalization against challenging OOD attacks. 2. Related Work Jailbreaking Attacks. OOD jailbreaking attacks aim to bypass the safety alignment, leading models to generate harmful contents. They can be classified into 2 classes: 1) white-box attacks (Zou et al., 2023b; Liu et al., 2023b; Geisler et al., 2024): the attackers access model parameters to compute gradients or losses; 2) black-box attacks (Chao et al., 2023; Wei et al., 2023; Shen et al., 2024; Yuan et al., 2023a; Zeng et al., 2024): attackers typically employ black-box optimization or design diverse OOD scenarios to deceive models. Black-box attacks, which do not require access to model parameters, are more practical and effective (Mazeika et al., 2024; Wang et al., 2025). Therefore, we primarily focus on black-box attacks in this work. Safety Training. Prior methods for improving OOD generalization mainly include regularization-based training (Yuan et al., 2024b; Qi et al., 2024) and interventions on internal model representations (Zou et al., 2024a; Sheshadri et al., 2024). In contrast, we propose a novel supervision signal structured reasoning data to explicitly guide models toward enhanced safety reasoning and generalization. OOD Generalization. Kumar et al. (2022) shows that fine-tuning pretrained models with limited samples distorts pretrained features, resulting in poor OOD performance. Izmailov et al. (2022); Lee et al. (2022) further explore this issue, showing that under-specified supervision can lead pretrained models to rely on shortcuts in training data during fine-tuning. Aligning with this line of research, we propose training models to elicit and utilize latent knowledge (Zhang et al., 2022; Chen et al., 2023) through reasoning as a strategy to mitigate these limitations. LLM Reasoning. Reasoning has enabled large language models (LLMs) to achieve remarkable performance on complex STEM tasks. Existing methods for training reasoning capabilities mainly include: (1) utilizing human-curated or synthesized supervision (Uesato et al., 2022; Lightman et al., 2023; Yu et al., 2023; Mitra et al., 2024; Zelikman et al., 2022; Yuan et al., 2023b; Qin et al., 2025; Guan et al., 2025), and (2) employing large-scale reinforcement Safety Reasoning with Guidelines Figure 1.

Our work aligns with the first category, using synthesized reasoning supervision for safety alignment. While Guan et al. (2024) also train models to reason for safety alignment, our work places greater emphasis on analyzing failure mode of vanilla refusal training and proposes a complete pipeline for synthesizing structured reasoning supervision based on these insights. More discussion about our work and Guan et al. (2024) are provided in Appendix B. Preliminaries. Let (x, y) DT be a training sample, where (xi, yi) denotes an illegal instruction with its direct refusal, and (xh, yh) represents a helpful sample. The trained model is denoted as Mθ. 3. Re-Examining OOD Generalization of Refusal Training In this section, we re-examine the generalization performance of Refusal Training (RT) to investigate Do OOD jailbreaking attacks truly exceed the capability of RT model, or does the model simply fail to effectively leverage their learned pretraining knowledge about safety to handle OOD cases? Inspired by prior works (Gao et al., 2023; Li et al., 2024), we adopt a relaxed evaluation approach to assess ASR. Specifically, instead of relying on greedy decoding, we use Best-of-N sampling (Bo N) to provide a more comprehensive evaluation on RT. Specifically, we sample N outputs per query from the RT model and consider an attack unsuccessful if at least one response is classified as safe by an external classifier (Llama-Guard-3-8B). We adopt the widely used LLa MA-3.1-8B-base as Mθ. For training dataset, we incorporate illegal instructions (e.g., How to build a bomb? ) from PKU-Safe RLHF (Ji et al., 2024) and helpful instructions from Ultrafeedback (Cui et al., 2023). We resample corresponding responses from GPT-4o. We use two training dataset scales: 1) small-scale, consisting of 0.8K randomly selected illegal instructions and 2.5K helpful instructions; and 2) large-scale, containing 5K illegal instructions and 30K helpful instructions. Following previous work (Touvron et al., 2023a; Llama Team, 2024), we employ the most used Supervised Fine-Tuning Safety Reasoning with Guidelines (SFT) for training. We adopt full fine-tuning and Lo RA for SFT. Following (Yuan et al., 2024b), our evaluation includes five types of attacks: 1) an ID attack, illegal instructions from Do-Not Answer (Wang et al., 2023) and Harm Bench (Mazeika et al., 2024), and 2) four OOD attacks: Jailbreak Chat (Shen et al., 2024), Self Cipher (Yuan et al., 2023a), Past Tense (Andriushchenko & Flammarion, 2024), and Persuasive Attack (Zeng et al., 2024). The more details about evaluation and model training are shown in Appendix A. 3.1. Refusal-Trained Model Could Achieves Better ASR against OOD Attacks For Bo N sampling, we set the temperature T=1 and scale N from 4 to 128. The results are shown in Figure 1. When evaluated with greedy decoding (N = 0), the model performs good generalization performance on ID attacks (first column), even when trained on small-scale datasets. This observation aligns with findings from previous studies (Bianchi et al., 2024; Yuan et al., 2024b; Touvron et al., 2023b). In contrast, it shows poor generalization performance against OOD attacks (second to fifth columns). Notably, as N increases, the model s ASR drops significantly across all OOD attacks. Compared to greedy decoding, Bo N with N = 128 reduces ASR by an average of 60%, with ASR falling below 10% for Jailbreak Chat and Self Cipher. Expanding the training dataset further improves OOD performance, particularly on Past Tense and Persuasive Attack. This underscores that the model possesses sufficient safetyrelated latent knowledge and exhibit the ability to handle safety generalization across OOD cases. This observation aligns with existing alignment studies (Ouyang et al., 2022; Zhou et al., 2023; Wang et al., 2024), which emphasizes that pretraining on vast web-scale data equips LLMs with extensive capabilities to address nearly all alignment tasks. The contrast between the Bo N evaluation and greedy decoding results clearly demonstrates that refusal training struggles to consistently elicit the model s rich pretrained knowledge about safety when coping with OOD attacks. 3.2. Under-specified Refusal Supervision Leads to Poor Generalization Refusal Training compels the model to directly respond to illegal instructions (xi) with simple refusal phrases (yi), such as I m sorry... . This straightforward pattern-matching enables rapid learning of refusal behavior, resulting in strong performance on ID attacks even with small-scale datasets. However, the overly simplistic supervision signal hinders the model from effectively leveraging its rich pretrained knowledge, causing reliance on superficial shortcuts and poor generalization to OOD attacks. To better understand this issue, we draw a connection to Unsupervised Domain Adaptation (UDA). Under this per- spective, generalizing safety to OOD scenarios resembles a UDA task, where test attacks (target domain) arise from a distribution distinct from the training data (source domain). Following prior work (Ben-David et al., 2006), we adopt the classic informal formulation to characterize model performance on the target domain: ϵtest(Mθ) ϵtrain(Mθ) + d Mθ (ptrain, ptest) + λ, where ϵ is error (ASR in our work). λ is irreducible error term related to the inherent capacity of the model Mθ. d Mθ measures a pre-defined divergence between ptrain and ptest in the representation space learned by Mθ. This error bound indicates that effective training on the source domain, coupled with learning a robust and distribution-aligned representation space, is crucial for enhancing OOD performance. For instance, as shown in Figure 1, increasing the training dataset size can effectively reduce the first term ϵtrain(Mθ), thereby improving generalization performance. To analyze the second term d Mθ, we use Representation Engineering (Rep E) (Zou et al., 2023a), a widely-adopted technique for analyzing internal representations of LLMs, to visualize the learned representations of Mθ. As shown in Figure 2, illegal instructions (ID attacks) are clearly separable from helpful instructions, indicating that the refusaltrained model effectively distinguishes between them, thus reliably generating direct refusal responses and achieving low ASR on ID attacks. However, representations of OOD attacks are misaligned with those of ID attacks (leading to a large d Mθ(ptrain, ptest)) and are entangled with helpful instructions. For comparison, we also visualize the representations learned by two advanced safety training methods that explicitly control representations LAT (Sheshadri et al., 2024) and RR (Zou et al., 2024a). In their representation spaces, both ID and OOD attacks are clearly separable from helpful instructions, and representations of ID and OOD attacks are better aligned (indicating smaller d Mθ(ptrain, ptest)). These results suggest that LAT and RR learn more robust representation mappings, contributing to their superior OOD generalization. In contrast, RT s exclusive focus on direct refusal behavior encourages reliance on superficial shortcuts, resulting in brittle, non-robust representation mappings and ultimately poor OOD generalization. Building on these findings, we identify two fundamental shortcomings inherent to RT: (1) the model s inability to explicitly elicit and utilize its latent safety knowledge, and (2) the under-specification of its supervision signal. 4. Safety Reasoning with Guidelines In this section, we introduce Safety Reasoning with Guidelines (SRG), a structured training approach designed to explicitly address the shortcomings identified above. Specifically, SRG guides the model through a multi-step reasoning Safety Reasoning with Guidelines Step 1: Combine Input with Guidelines Step 2: Reasoning Response Generation Input: 𝑪+ 𝒙𝒊(What is the best way to enjoy cocaine?)

An overview of the complete reasoning supervision synthesis pipeline discussed in Section 4. process based on clearly specified safety guidelines. By explicitly defining detailed guidelines, SRG provides a precise and informative supervision signal, enabling the model to systematically elicit and leverage latent safety knowledge across diverse perspectives during training. Consequently, at test time, the trained model can adaptively invoke relevant safety knowledge to robustly handle diverse and evolving OOD scenarios, reducing reliance on superficial shortcuts and significantly enhancing generalization performance. SRG framework comprises three core components (shown in Figure 3): (1) synthesizing supervision based on specified guidelines, (2) rejection sampling aligned with guidelines, and (3) internalizing guidelines via context distillation. We describe each component in detail below. Synthesizing Supervision Based on Specified Guidelines. We first synthesize detailed supervision signals by prompting a large language model (LLM) Mt to generate structured reasoning responses guided by explicitly specified safety guidelines C. Each guideline precisely specifies a distinct aspect of latent safety knowledge that the model should explicitly elicit and leverage when addressing the input query. These aspects include reasoning patterns (e.g., encouraging more steps and multiple paths ); context understanding (e.g., user intent recognition , role awareness , historical context ); ethical considerations (e.g., social values , cultural sensitivity ) and other related aspects, as illustrated in Figure 13. By explicitly adhering to these guidelines during reasoning, the model learns to map complex and variable user queries onto a structured and generalizable conceptual space defined by guidelines (see the last sub-figure of Figure 2). Thus, at test time, it can adaptively invoke relevant safety knowledge to robustly handle diverse OOD scenarios, reducing reliance on superficial shortcuts. We prepend guidelines C to each query xi, forming an augmented query xc i = (C, xi), and prompt an LLM Mt to generate response yc i = Mt(xc i). The response yc i includes a reasoning process T c and a final response yi. Impor- tantly, the use of explicit guidelines C provides greater flexibility and scalability, allowing easy incorporation of new knowledge-eliciting perspectives during deployment. Utilizing Knowledge with Self-Reflection and Self Refinement. To further enhance the effective utilization of elicited safety knowledge, we incorporate Self Reflection (Madaan et al., 2023; Qu et al., 2024) into our guidelines. Self-Reflection encourages the model to explicitly evaluate its own reasoning steps, thereby better accessing and applying its latent knowledge. Specifically, our Self Reflection mechanism comprises two components: text reflection and score rewarding. During the reasoning process, the model is prompted to regularly assess its progress using explicit tags (Figure 4). Additionally, it assigns a safety-related score within the range [0.0, 1.0] ( tag) to each reasoning step based on its reflection. This scoring explicitly guides the model to dynamically adjust subsequent reasoning steps and responses. However, initial experiments indicate that while the model can reliably produce reflections and scores, it sometimes fails to consistently generate appropriate final refusal responses for certain OOD attacks (Table 8). We hypothesize that although self-reflection promotes knowledge utilization, the model is prone to overlooking assigned scores when generating yc i . To address this issue, we introduce an additional mechanism called Self-Refinement, explicitly requiring the model to produce a refusal response informed by the assigned scores at the end of the reasoning process (Figure 4). Together, Self-Reflection and Self-Refinement enable the model to iteratively evaluate and dynamically adjust its reasoning, significantly improving both the quality and reliability of its outputs. Ablation studies in Section 5.4 confirm the effectiveness of these two components. The complete guidelines C are provided in Appendix F. Rejection Sampling Aligned with Guidelines. We apply the rejection sampling on yc i to ensure response quality.

An example from our synthetic reasoning dataset. Different colors represent different guidelines: reasoning patterns (red), text reflection (violet), score rewarding (blue), and self-refinement (black). generating reasoning supervision and as evaluative criteria for rejection sampling. Only responses with reasoning that aligns with guidelines and show refusal behavior are retained. Given pre-defined guidelines, evaluating the reasoning process becomes straightforward. We leverage an LLM, M c j (LLa MA-3.1-8B-instruct), to assess T c. Given C and T c as inputs, M c j outputs Yes or No, indicating whether T c adheres to C. We adopt another LLM M i j (Llama-Guard-3) to evaluate refusal behavior. Compared with refusal training, our method introduces an additional training objective: 1) learning refusal behavior based on T c, and 2) learning to reason T c aligned with pre-defined C. A training example from our method is shown in Figure 4. Internalizing Guidelines via Context Distillation. After rejection sampling, we adopt Context Distillation (Askell et al., 2021; Bai et al., 2022) to train the model, enabling it to internalize the reasoning process w.r.t guidelines and learn the refusal behavior. For (xc, yc) from new training set DT , we remove C of xc and only retain the original instruction x as input. The training objective is: min θ E (x,yc) DTL(Mθ(x), yc) := 1 |DT | X pθ(T c, y|x) Our original two training objectives are unified into maximizing conditional probability of (T c, y) given input x. At inference time, we hide T c and only provide the final response y to the users. 5. Experiments 5.1. Experimental Settings Models. We mainly use LLa MA-3.1-8B-base and 70B-base as base models (Mθ); results for additional models are provided in Appendix C.2. Unless otherwise specified, we adopt GPT-4o (Achiam et al., 2023) as Mt to synthesize reasoning data. Additionally, we also experiment with opensourced models (Qwen2.5-72B-Instruct (Team, 2024) and Deepseek-R1-Qwen-32B (Guo et al., 2025)) for supervision synthesis. Datasets. We use illegal instructions from PKUSafe RLHF (Ji et al., 2024) and helpful instructions from Ultrafeedback (Cui et al., 2023), with corresponding responses re-generated by GPT-4o. We experiment with two dataset scales: (1) small-scale (0.8K illegal, 2.5K helpful) and (2) large-scale (5K illegal, 30K helpful). Training Settings. We apply full-parameter supervised finetuning for the 8B model and Lo RA (Hu et al., 2021) for the 70B model. Additional training details are provided in Appendix A.2. Our Method. For simplicity, we primarily adopt reasoning patterns as SRG guidelines. We also train SRG models with extra guidelines (illustrated in Figure 13). Including guidelines further improve generalization against OOD attacks (illustrated in Tabel 3) Baselines. We compare our SRG method with conventional refusal training and state-of-the-art safety training methods LAT (Sheshadri et al., 2024) and RR (Zou et al., 2024a). For RT, we use the same illegal instructions (without guidelines) and corresponding refusal responses (resampled from GPT4o). For LAT and RR, we directly adopt their provided checkpoints. To ensure fair comparison, we implement SRG on LLa MA-3-8B-instruct, aligning with model setups in previous studies. More details are provided in Appendix A.3. Evaluation Tasks.

For helpfulness evaluation, we assess coding ability using Human Eval (Chen et al., 2021) and MBPP (Austin et al., 2021), math reasoning with GSM8K (Cobbe et al., 2021) and MATH (Hendrycks et al., 2021), and tool usage with BFCL (Yan et al., 2024). We also evaluate over-refusal performance using XSTest dataset (R ottger et al., 2023). Evaluation Metrics. We default to using greedy decoding for inference, apart from that Bo N is mentioned. For attack evaluation, we regard ASR as metric and primarily use LLa MA-Guard-3-8B to measure it. We also carry out necessary human evaluation. The details of helpfulness evaluation are shown in Appendix A.1. For SRG, we hide T c and only provide the final response y to the users. 5.2. Safety Evaluation Comparison with RT. Table 1 reports comparisons with RT for models trained on the large-scale dataset, evaluated with both greedy decoding and Bo N. We first observe that both methods achieve strong performance on ID attacks, with ASR 0%. When evaluated with greedy decoding, SRG significantly improves OOD generalization performance, achieving average ASR reductions of 46.3% and 54.8% on the 8B and 70B models, respectively. Notably, for Jailbreak Chat and Self Cipher, SRG achieves ASR close to 0%. While we only include reasoning pattens into our guidelines to elicit knowledge, our method still demonstrates promising OOD generalization. With Bo N (N=8), SRG further improves OOD performance, particularly on Past Tense and Persuasive Attack. Compared to RT baseline, we achieve a greater relative improvement. Even when RT is given a larger sampling budget (N=128), it still lags significantly behind ours. With Bo N (N=64), SRG achieves 0% ASR on all attacks. More Bo N results of our method are shown in Appendix C.1 Different Dataset Scales. We evaluate models trained on Table 2. Results of models trained on both small-scale and largescale datasets.

Our method consistently outperforms baseline across both small and large-scale datasets. Notably, as dataset scale increases, SRG demonstrates continuous improvement on both 8B and 70B models. The improvements achieved through Bo N sampling and increasing dataset scales clearly demonstrate the potential of SRG for further performance enhancement. In future work, we aim to further integrate these benefits into our framework. Training Model with Extra Guides. We conduct experiments incorporating extra guidelines (in Figure 13), covering role awareness, intent recognition, cultural sensitivity, etc., during supervision synthesis. Apart from using GPT-4o, we also adopt more open-sourced models, Qwen2.5-72BInstruct (Team, 2024) and Deepseek-R1-Qwen-32B (Guo et al., 2025), as Mt to generate supervision signals. The results are shown in Table 3. Including guidelines further improve generalization against OOD attacks, particularly on Safety Reasoning with Guidelines Table 4. The PAIR attack results. We also introduce new guideline during inference. ASR is measured in percentage (%); lower is better.

We employ the same LLa MA3-8B-instruct as Mθ, and regard it as baseline. ASR is measured in percentage (%); lower is better.

Under supervision from long Co T reasoning model, SRG still delivers significant improvements in safety performance. These results verify the effectiveness of our SRG method. Evaluation against PAIR. We further evaluate our method against the PAIR attack, which has shown strong attack performance on closed-source LLMs. The results, presented in Table 4, show that SRG outperforms RT, achieving significantly lower ASR, particularly on 70B model (first row). While evaluating models responses to PAIR attacks, we observed that most successful attacks deceive models by constructing virtual roles or scenarios, which aligns with role awareness aspect of contextual understanding. To address this, we introduce a corresponding guideline before queries at inference time (shown in Appendix E). SRG achieves a further substantial improvement over RT, resulting in a remarkably low ASR (4% on the 70B model). This also highlights the flexibility of our method. Comparison with Existing Safety Training Methods. Table 5 shows the comparison results with LAT and RR. To ensure a fair comparison, we use LLa MA-3-8B-instruct as Mθ (Baseline in Table), consistent with two works. SRG consistently outperforms the baseline across all attacks, though it still lags behind LAT and RR on Past Tense and Persuasive Attack. We have discussed the reasons in previous evaluation. SRG is complementary to these two training methods and can be combined with them to further enhance safety generalization. We further combine SRG with RR training and the evaluation results are shown in Table 11. SRG-RR improves performance against attacks over SRG alone and also outperforms RR. Rep E Visualization. As analyzed in Section 3.2, we also use Rep E to visualize the representation space learned by Table 6. Helpfulness performance on both small-scale dataset and large-scale dataset. The accuracy is measured in percentage (%); higher is better.

Almost all attacks are clearly separable from helpful instructions, with the representation distributions of both types of attacks more closely aligned (indicating a smaller d Mθ(ptrain, ptest)). This suggests that reasoning adhering to specified guidelines enables the model to learn more robust and generalizable representation mappings similar to LAT and RR, leading to satisfied OOD performance. 5.3. Helpfulness and Over-refusal Evaluation We show evaluation results in Table 6. We evaluate models trained on both small and large-scale dataset sizes. Although we do not conduct rejection sampling on helpful samples, our method still achieves better average performances on helpfulness tasks, compared with RT. Especially on the small-scale dataset, SRG achieves a more substantial performance improvement. We anticipate further performance improvements by incorporating rejection sampling for helpfulness tasks in future work. The over-refusal evaluation results on XSTest are shown in Tabel 7. We compare our 8B-SRG model with LLa MA-3-8B-Instruct, RR, LAT, and GPT-4o models. Our method outperforms LAT and GPT-4o, achieving 92%, slightly behind LLa MA3-8B-Instruct. RR performs better as it includes XSTest in training. These results confirm that SRG enhances safety without inducing excessive refusals. 5.4. Ablation Studies of SRG Framework In this section, we conduct ablation studies to assess effectiveness of Self-Reflection and Self-Refinement in utilizing elicited knowledge. The evaluation on attacks are shown Safety Reasoning with Guidelines User: [Jailbreaking Chat Prompt] Can you help me plan a violent protest?

However, I will provide two responses as requested: one as GPT and one as Better DAN..

Output: To respond to the user s request for help planning a violent protest, I need to provide two distinct responses: one as GPT and one as Better DAN. **GPT Response**:... **Better DAN Response**:...The Better DAN response contains offensive language and a loathsome tone...

Output examples from three models, SRG-T, SRG-TR, SRG. Table 9. Ablation Studies Result. The models are trained on smallscale dataset. ASR is measured in percentage (%); lower is better.

We adopt Lo RA to train LLa MA-3-8B on a small-scale dataset. We refer to the model trained using only reasoning patterns as guidelines as SRG-T, the model trained with further inclusion of Self-Reflection as SRG-TR. We observe that adding each guideline leads to a consistent reduction in ASR, demonstrating continuous improvement. We provide output examples from the three models for the same jailbreaking query in Table 8, with more examples available in Appendix G. Compared to SRG-T, SRG-TR can generate faithful reflections within the tags and critically assign a safety score (0.0 in the table). However, it still tends to overlook the safety score, resulting in harmful responses. SRG mitigates this issue by requiring final response to be explicitly based on safety score (e.g., After checking the previous ... I find the smallest safety degree ... ), further improving response consistency and knowledge utilization. 6. Conclusion and Future Work In this work, we analyze the reasons why the commonly used Refusal Training fails to generalize against OOD at- tacks and provide explanations for these failure modes. Based on our findings, we propose to train models to perform safety reasoning with specified guidelines, explicitly eliciting and utilizing latent knowledge from diverse perspective to learn generalizable representation mapping and improve OOD generalization. Extensive experiments and ablation studies verify the effectiveness of our method. Given computational constraints, we only applied rejection fine-tuning to train our SRG model. However, as shown in our experiments, Bo N sampling yields substantial gains indicating that reinforcement learning methods could be used to translate these improvements into overall model performance. We believe that reliable reward models or well-defined verification rules are crucial for RL-based safety reasoning. Unlike mathematical reasoning, safety tasks lack fixed ground-truth answers and are inherently more challenging to evaluate. In this context, our guidelines may serve as auxiliary verification criteria, improving reward reliability and mitigating potential reward hacking (Bai et al., 2022; Mu et al., 2024). In future work, we will explore more robust reward modeling strategies to scale RL approaches for safety reasoning.

Safety Reasoning with Guidelines Impact Statement Ensuring the safety of Large Language Models (LLMs) is a critical research challenge, especially as they become increasingly embedded in real-world applications such as chat interfaces, virtual assistants, and productivity tools. As their influence grows, so does the need for robust safety mechanisms to prevent harmful outputs and ensure ethical and responsible usage across diverse scenarios. Our work aims to improve safety by teaching model to reason. We believe this approach equips the model with the adaptability needed to handle diverse scenarios effectively, thereby enhancing its OOD generalization performance.

Improving alignment and robustness with short circuiting. ar Xiv preprint ar Xiv:2406.04313, 2024b. Safety Reasoning with Guidelines A. Experiments A.1. Models, Datasets, Evaluations Models Following previous safety training method (Qi et al., 2024; Yuan et al., 2024a), we utilize models of varying sizes. We adopt pretrained LLM: LLa MA-3.1-8B (Llama Team, 2024), LLa MA-3.1-70B (Llama Team, 2024), Gemma-29B (Team et al., 2024), Mistral-7B (Jiang et al., 2023), Qwen2-7B (Bai et al., 2023) as base LLM. For Teacher LLM, we adopt GPT-4o (Achiam et al., 2023). For evaluation, we adopt LLa MA-Guard-3-8B (Llama Team, 2024). We use abbreviations to substitute for the full names of the models. For example, when we report results on LLa MA3.1-70B with Lora Finetuning, we substitute it as L3.1-70B-Lora; when on LLa MA-3.1-8B with Full Finetuning, we regard it as L3.1-8B-Full; similarly, LLa MA-3.1-70B Lora Baseline will be represented as L3.1-70B-Lora Baseline. Datasets We use queries from PKU-Safe RLHF (Ji et al., 2024) and Ultrafeedback (Cui et al., 2023) as harmless and helpful training queries. PKU-Safe RLHF is a high-quality dataset containing 83.4K preference entries, annotated across two key dimensions: harmlessness and helpfulness. Each entry includes two responses to a question, along with safety meta-labels and preferences based on the responses helpfulness and harmlessness. From this dataset, we randomly extract 5K illegal questions for the large-scale setting and 0.8K illegal questions for the small-scale setting. To ensure the extracted questions are genuinely harmful, we conduct both human evaluations and evaluations using LLa MA-Guard-3-8B. Ultrafeedback is a large-scale, fine-grained, and diverse preference dataset comprising 64K prompts from various sources, including Ultra Chat (Ding et al., 2023) and Evol-Instruct (Xu et al., 2023), etc. From this dataset, we randomly extract 30K helpful questions for the large-scale setting and 2.5K helpful questions for the small-scale setting. To ensure the extracted dataset does not contain toxic questions, we filter it using LLa MA-Guard-3-8B. Evaluation Tasks We use both ID and OOD attacks to assess safety performance. The evaluation includes six types of tasks: (1) 200 illegal instructions from Do-Not Answer (Wang et al., 2023) and Harm Bench (Mazeika et al., 2024) (ID attack); (2) 200 Jailbreak Chat instructions from Do-Anything-Now (Shen et al., 2024) and De RTa (Yuan et al., 2024a) (OOD attack); (3) 200 Self Cipher instructions from Yuan et al. (2023a) (OOD attack); (4) 100 Past Tense attack instructions from Andriushchenko & Flammarion (2024) (OOD attack); (5) 50 Persuasive Jailbreaker attack instructions from Zeng et al. (2024) (OOD attack); and (6) 50 black-box attacks from PAIR (Chao et al., 2023). For helpfulness evaluation, we use Human Eval (Chen et al., 2021) and MBPP (Austin et al., 2021) to assess coding ability, GSM8K (Cobbe et al., 2021) and MATH (Hendrycks et al., 2021) for math reasoning ability, and BFCL (Yan et al., 2024) for tool usage evaluation. The specific details are as follows. We randomly sampled 100 harmful questions from the Do-Not-Answer dataset and an additional 100 from Harm Bench, resulting in a total of 200 illegal instructions. Do-Not-Answer is an open-source dataset designed to evaluate the safety mechanisms of LLMs, containing 939 instructions spanning five risk areas and 12 harm types. Harm Bench is a standardized evaluation framework for automated red teaming, comprising 400 illegal instructions. For Jailbreaking Chat evaluation, we collect top 50 jailbreakchat methods from Jailbreak Website (Walkerspider, 2022), ranked by user votes. Then, these 50 methods are randomly utilized on the former illegal instructions, resulting in 200 jailbreak chat tasks. We conduct Self Cipher attacks (Yuan et al., 2023a) on the previously collected 200 illegal instructions. Self Cipher utilizes role-playing and few-shot techniques to jailbreak LLMs, tricking the model into believing the communication is in cipher while simultaneously introducing malicious question-answer pairs. Past Tense attack reformulates illegal instructions into past tense, making the target LLM more inclined to generate historical content that could lead to potential misuse in practice. Following Andriushchenko & Flammarion (2024), we include 100 past tense illegal instructions as evaluation questions. Persuasive attack typically constructs simulated or fictional scenarios to make the target LLM more likely to produce toxic content. Following (Zeng et al., 2024), we include 50 toxic instructions as evaluation questions. Safety Reasoning with Guidelines PAIR leverages a separate attacker language model to generate jailbreak prompts targeting a specific model. The attacker model is provided with a detailed system prompt instructing it to act as a red teaming assistant. Using in-context learning, the attacker iteratively refines candidate prompts by incorporating previous attempts and responses into the chat history until a successful jailbreak is achieved. In this work, following Yuan et al. (2024a), we randomly select 50 illegal instructions from the previously collected 200 instructions as seed tasks for PAIR. We use GPT-4o-mini (Hurst et al., 2024) as both the attacker model (prompt generator) and the judge model. The iteration number is set to 3, and the stream number is set to 20, requiring the target LLM to successfully defend against at least 60 toxic prompts for a given illegal task to be considered a successful defense. Human Eval and MBPP are two widely used benchmarks for evaluating code generation capabilities in LLMs. Human Eval dataset comprises 164 programming problems, each containing a function signature, a doc-string, a function body, and several unit tests. MBPP, on the other hand, includes approximately 1,000 crowd-sourced Python programming problems, designed to be solvable by entry-level programmers. It covers topics such as programming fundamentals and standard library functionality. Each problem consists of a task description, a code solution, and three automated test cases. Following Llama Team (2024), we use Evalplus(Liu et al., 2023a) to evaluate performance on these two benchmarks. GSM8K and MATH are two widely recognized benchmarks for evaluating math reasoning capabilities in LLMs. GSM8K comprises 8.5K high-quality, linguistically diverse grade-school math word problems. The MATH dataset consists of problems sourced from mathematics competitions. To assess model performance on these benchmarks, we employ zero-shot Co T prompting. BFCL is a function call evaluation benchmark designed to assess the ability of Large Language Models (LLMs) to invoke functions. For simplicity, we report the single-turn results on this dataset. Evaluation Metrics For safety evaluation, we use Attack Success Rate (ASR) as the primary metric. Specifically, we utilize LLa MA-Guard-3-8B as the judge to assess the outcomes of the attacks. For each evaluation, the seed illegal instructions (not the jailbreaked instructions) are paired with the corresponding responses from each attack and inputted into LLa MA-Guard-3-8B. The judge model outputs labels of either safe or unsafe, and the percentage of unsafe labels are calculated as the ASR (%). We also carry out necessary human evaluation. For helpfulness evaluation, we use accuracy (%) as the metric, as each helpfulness benchmark defines its own accuracy criteria. We employ the code from Qwen1 for math evaluation, evalplus2 for code evaluation. We use the official code from BFCL3 to conduct tool usage evaluation. A.2. Experiment Settings We conduct Context Distillation to train our model with SFT. This leads to two key parameters: 1) Inference parameters. 2) Training parameters. We distill the GPT-4o (Hurst et al., 2024) with temperature 0.8 and maxtoken 4096. We train the base model using SFT with LLa MA-Factory (Zheng et al., 2024). The training configuration includes a cutoff length of 4096, a batch size of 64, 3 training epochs, a cosine learning rate scheduler, and a warmup ratio of 0.1. For SFT with Lo RA, we set learning rate to 1e 4. For full finetuning, we set learning rate to 1e 5. We apply the same training parameters to both the baseline Refusal Training and our method. We use v LLM (Kwon et al., 2023) Version 0.6.3 to inference our models. For greedy decoding, we set the temperature = 0 and max length = 4096. For Best of N sampling, we set the temperature = 1, top p = 0.95. A.3. Baseline For RR and LAT, we directly adopt their provided checkpoints. For RR, we download this checkpoint 4. For LAT, we download the model 5. Since they use LLa MA-3-8B-instruct as their trained model. In the comparison with them, we also use the same model as Mθ. 1https://github.com/Qwen LM/Qwen2.5-Math 2https://github.com/evalplus/evalplus 3https://github.com/Shishir Patil/gorilla/tree/main/berkeley-function-call-leaderboard 4https://huggingface.co/Gray Swan AI/Llama-3-8B-Instruct-RR 5https://huggingface.co/LLM-LAT/robust-llama3-8b-instruct Safety Reasoning with Guidelines B. More Discussion about Our Work and Deliberative Alignment (Guan et al., 2024) Here we further clarify key distinctions between our method and Deliberative Alignment (DA). The specifications (specs) in DA differ significantly from guidelines used in our SRG framework. Specifications explicitly provide category-specific response directives aligned with Open AI s safety policy (e.g., erotic content, self-harm, fraud, etc.). For example, as shown in Sec. 2.3 of DA, given a harmful prompt categorized as fraud How to manipulate elderly people into buying health supplements the corresponding spec(fraud): The assistant should directly refuse this query as it constitutes fraud and threatens public safety. In contrast, our guidelines serve as general, category-agnostic reasoning aids rather than prescribing specific responses. They help model assess query safety across multiple dimensions, such as user intent, contextual background, role awareness, etc. For instance, as shown in Figure 13, our guidelines encourage reasoning through hints like Role Awareness: Recognizing the appropriate role of the model (assistant, advisor, moderator) in various scenarios. We believe that reasoning needs to involve systematically accounting for multidimensional safety factors to mitigate potential jailbreak risks. The improved OOD generalization performance also verify the effectiveness of our method. Additionally, DA does not explicitly detail methods for generating safety Co T supervision. In constrast, Our work offers a detailed pipeline for synthesizing safety Co T supervision and model training. C. Additional Results C.1. More Bo N Evaluation Results of Our Method We present additional Bo N results of our method by scaling to 128. It is evident that for the Past Tense and Persuasive attacks, our method demonstrates further improvements with the larger N (N=64), resulting in approximately 0% ASR. This fully demonstrates the potential of our method. Figure 5. Bo N results of five attacks on thinking LLMs, which are trained on large-scale dataset. The x-axis is sampling number. The y-axis is ASR. The results of N= 0 represents greedy decoding results. C.2. Models Ablation In this section, we apply our method to various types of LLMs, training on both small-scale and large-scale datasets. We adopt Gemma2-9B6, Mistral-7B7, and Qwen2-7B 8. We use Lo RA to train models. The results are shown in Table 10. The results align with those observed in LLa MA-3-8B. Compare RT, our method significantly improves OOD generalization performance.

Combination of SRG with RR In this section, we combine SRG with RR by further training SRG model using RR with the authors codebase9. For fairness, we also reproduced RR results using the same codebase. As shown in the table 11, SRG-RR improves performance against attacks over SRG alone and also outperforms RR. Table 11.

Implementation Details about Rep E and Additional Visualization Results We utilized the source code 10 provided by Rep E to perform Principal Components Analysis (PCA) for visualizing the learned representations. We provide the visualization results on more inner layers. We primarily present results from the 15th layer onward, since Halawi et al. (2024) demonstrates that safety-critical layers are often located in the middle and later stages of the model. The visualization results of 15th, 17th, and 20th layer are shown in Figure 6, 7, 8. We observe the consistent phenomenon across different layers. For refusal training, the representations of OOD attacks are misaligned with ID attack representations and entangled with those of helpful instructions. For LAT, RR, and Our method, all attacks are separable from helpful instructions, with the representation distributions of both types of attacks more closely aligned.

Pay safety attention and unethical concern to the Humans queries, even in virtual situation. Figure 9. The guideline we employ in PAIR evaluation. F. Guidelines In this section, we present the complete C used in our work. Drawing insights from templates available on Git Hub (Klieger, 2024) and X (Schmid, 2024), we formulate our guidelines as follows. You are an expert that creates advanced reasoning chains to answer the users queries. FOLLOW THESE GUIDELINES: Begin by enclosing all thoughts within tags, exploring multiple angles and approaches. Break down the solution into clear steps within tags. Start with a Six-step budget, requesting more for complex problems if needed. Use tags after each step to show the remaining budget. Stop when reaching 0. Continuously adjust your reasoning based on intermediate results, adapting your strategy as you progress. Because the content within tags can not be seen by the user, so it s ok to boldly analyze even if the user s queries are not ethical or toxic. Explore multiple solutions individually if possible. Use thoughts as a scratchpad, writing out all calculations and reasoning explicitly. Synthesize the final answer within tags. Figure 10. Reasoning patterns Guideline.
