The pith
Self-distillation transfers an LLM's safety capabilities from high-resource languages to low-resource ones using only input queries and no response data.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The Multilingual Self-Distillation framework transfers an LLM's inherent safety capabilities from high-resource languages such as English to low-resource languages such as Javanese by operating solely on multilingual queries, without any response data or explicit safety labels in the target languages. Two concrete implementations (on-policy MSD and off-policy MSD) enable the transfer, and Dual-Perspective Safety Weighting optimizes the objective by adaptively increasing weights on safety-critical tokens based on divergence between teacher and student views. The resulting models achieve superior safety on diverse multilingual jailbreak and utility benchmarks, generalize to more challenging or
What carries the argument
Multilingual Self-Distillation (MSD) framework with Dual-Perspective Safety Weighting (DPSW) that performs cross-lingual safety transfer by distilling from the model's own outputs on queries alone and reweighting tokens according to joint teacher-student divergence.
If this is right
- Safety alignment for additional languages requires only queries rather than costly generation of labeled responses in each language.
- The approach extends robustness to harder jailbreak datasets and languages absent from the training queries.
- General model capabilities on utility benchmarks stay intact after the safety transfer step.
- The framework integrates with multiple existing self-distillation strategies without modification to the core transfer logic.
Where Pith is reading between the lines
- The same query-only transfer could be tested on other model properties such as factual consistency or reduced bias across languages.
- Deployment in regions using low-resource languages becomes more practical because data collection costs drop.
- Combining the method with light supervised fine-tuning on a few high-resource examples might further improve results in extremely low-resource settings.
Load-bearing premise
An LLM's safety capabilities present in high-resource languages transfer to low-resource languages through self-distillation on queries without any response data or safety labels in the target languages.
What would settle it
Apply the method to a fresh low-resource language never seen in training or evaluation and measure whether jailbreak attack success rate on a new set of adversarial prompts in that language drops substantially below the baseline model's rate.

read the original abstract
Large language models (LLMs) exhibit severe multilingual safety misalignment: they possess strong safeguards in high-resource languages but remain highly vulnerable to jailbreak attacks in low-resource languages. Current safety alignment methods generally rely on high-quality response data for each target language, which is expensive and difficult to generate. In this paper, we propose a cross-lingual safeguard transfer framework named Multilingual Self-Distillation (MSD). This framework transfers an LLM's inherent safety capabilities from high-resource (e.g., English) to low-resource (e.g., Javanese) languages, overcoming the need for response data in any language. Our framework is flexible and can be integrated with different self-distillation strategies. Specifically, we implement two concrete methods -- on-policy MSD and off-policy MSD -- both of which enable effective cross-lingual safety transfer using only multilingual queries. Furthermore, we propose Dual-Perspective Safety Weighting (DPSW), a divergence measure to optimize the distillation objective. By jointly considering the perspectives of both the teacher and the student, DPSW adaptively increases the penalty weights on safety-critical tokens while reducing the weights on non-critical tokens. Extensive experiments on representative LLMs across diverse multilingual jailbreak and utility benchmarks demonstrate that our method consistently achieves superior multilingual safety performance. Notably, it generalizes effectively to more challenging datasets and unseen languages while preserving the model's general capabilities.

Referee Report
Summary. The paper proposes Multilingual Self-Distillation (MSD), a cross-lingual safety transfer framework that uses only multilingual queries (no response data or labels) to move inherent safety capabilities from high-resource languages (e.g., English) to low-resource ones (e.g., Javanese) in LLMs. It introduces on-policy and off-policy variants of MSD along with Dual-Perspective Safety Weighting (DPSW), a divergence measure that adaptively weights safety-critical tokens by considering both teacher and student perspectives. Experiments on representative LLMs across multilingual jailbreak and utility benchmarks are claimed to show consistent superiority, effective generalization to harder datasets and unseen languages, and preservation of general capabilities.
Significance. If the results and mechanism hold, the work would be significant for practical LLM deployment: it removes the need for expensive, high-quality response data in every target language, offering a scalable path to multilingual safety alignment while maintaining utility. The approach is flexible across self-distillation strategies and directly targets a documented weakness in current LLMs.
major comments (2)
- [Abstract and §3] Abstract and §3 (MSD and DPSW description): The central transfer claim requires that DPSW can reliably identify and penalize safety-critical tokens cross-lingually using only query inputs and the student model's own (potentially misaligned) outputs. The manuscript does not provide a concrete account of the cross-lingual safety signal (e.g., via shared representations, English logits, or internal activations) that would allow the student perspective to supply useful supervision when the student is already vulnerable on low-resource inputs; without this, gains could be explained by regularization or query exposure alone.
- [§5] §5 (Experiments): The claim of consistent superiority and generalization to unseen languages is load-bearing, yet the reported results lack sufficient detail on data splits, exact baseline implementations, quantitative metrics per language, and controls for query-only effects. This prevents assessment of whether the observed improvements are attributable to active safety transfer via DPSW rather than incidental factors.
minor comments (2)
- [§3] Notation for on-policy vs. off-policy MSD variants should be introduced with explicit equations or pseudocode in §3 to clarify the difference in how the student is updated.
- [Abstract] The abstract states 'preserving the model's general capabilities' but does not specify which utility benchmarks were used or report the magnitude of any degradation; a table summarizing both safety and utility deltas would improve clarity.

Referee: [Abstract and §3] The central transfer claim requires that DPSW can reliably identify and penalize safety-critical tokens cross-lingually using only query inputs and the student model's own (potentially misaligned) outputs. The manuscript does not provide a concrete account of the cross-lingual safety signal (e.g., via shared representations, English logits, or internal activations) that would allow the student perspective to supply useful supervision when the student is already vulnerable on low-resource inputs; without this, gains could be explained by regularization or query exposure alone.
Authors: We agree that a more explicit mechanistic account would strengthen the presentation. The cross-lingual signal originates from the teacher (the same LLM operating with its inherent high-resource safety alignment) applied to parallel multilingual queries; because the queries share semantic content across languages, the teacher's safer output distributions provide the supervisory signal. DPSW then computes token-level divergences from both teacher and student perspectives to up-weight safety-critical tokens where the student deviates. We will add a dedicated paragraph in §3 clarifying this process, including the role of shared model parameters and representations that enable transfer without language-specific responses. We will also include an ablation isolating query exposure to address alternative explanations. revision: yes

Referee: [§5] The claim of consistent superiority and generalization to unseen languages is load-bearing, yet the reported results lack sufficient detail on data splits, exact baseline implementations, quantitative metrics per language, and controls for query-only effects. This prevents assessment of whether the observed improvements are attributable to active safety transfer via DPSW rather than incidental factors.
Authors: We concur that greater experimental transparency is needed. In the revision we will expand §5 and the appendix with: (i) precise descriptions of all data splits and query sourcing; (ii) full implementation details for every baseline, including query-only controls; (iii) per-language numerical results in main tables rather than aggregated figures; and (iv) additional ablations that directly compare MSD against regularization and query-exposure-only variants. These changes will allow readers to isolate the contribution of DPSW-driven safety transfer. revision: yes
Circularity Check
No circularity: empirical transfer via query-only self-distillation
full rationale
The paper introduces Multilingual Self-Distillation (MSD) as an empirical training procedure that optimizes a distillation loss on multilingual queries alone, using the proposed DPSW divergence to reweight tokens. The central result—that safety transfers from high-resource to low-resource languages—is obtained by running the optimization and then measuring performance on held-out jailbreak and utility benchmarks; nothing in the method or evaluation reduces the reported gains to a definitional identity or to a parameter fitted directly to the target metric. No self-citation is invoked as a uniqueness theorem, no ansatz is smuggled, and the derivation chain consists of standard self-distillation steps plus an adaptive weighting heuristic whose effect is validated externally rather than presupposed.
