Safety Measurements for Fine-tuned LLMs Should be Grounded in Capability

arXiv:2606.03648v1 Announce Type: new Abstract: Adapting foundation large language models to a user's task or preferred style through fine-tuning can result in compromising the model's safety. Previous works examined the effects of fine-tuning on model safety in limited and seemingly random experimental settings. We argue that anchoring fine-tuning to a specific capability goal is essential for avoiding arbitrary empirical choices, allowing us to draw meaningful conclusions about safety impacts, and to compare mitigation methods on a consistent basis. We conduct a multi-dimensional evaluation

Why this matters
Why now

As fine-tuning LLMs becomes a pervasive practice for customization, the inherent safety risks are gaining critical attention from researchers to prevent widespread negative consequences.

Why it’s important

Ensuring the safety of fine-tuned LLMs is crucial for their responsible deployment across various industries and for maintaining public trust in AI technologies.

What changes

The focus on grounding safety measurements in capability establishes a more rigorous and comparable framework for evaluating and mitigating risks in customized AI models.
