Restoring Safety in Fine-Tuned LLMs
A post-hoc approach to recover safety alignment after fine-tuning
This research introduces IRR (Identify, Remove, and Recalibrate), a novel method to restore safety in language models that became unsafe during fine-tuning.
- Identifies and surgically removes unsafe parameter changes introduced during fine-tuning
- Maintains model performance on intended tasks while restoring safety guardrails
- Demonstrates effectiveness against harmful queries and jailbreak attacks
- Provides a practical solution for deploying fine-tuned models without compromising safety
This work addresses a critical security challenge for organizations using customized LLMs, offering a way to benefit from domain-specific fine-tuning without introducing new vulnerabilities or harmful behaviors.
