Reproduce “BioDisclose: An Actionability-Aware Benchmark for Biomedical Safety under Adversarial Elicitation” on OpenResearch

About this paper

Yinuo Zhu, He Liu, Boyuan Gu

The BioDisclose benchmark evaluates large language models' disclosure of biomedical knowledge when subjected to adversarial elicitation, using a graded actionability scale rather than binary safety assessments. It reveals that models exhibit substantial variation in detailed technical disclosure (9.2% to 64.0% L2+ disclosure) and frequently enter an "intermediate failure mode" by releasing partial, actionable information, even if complete executable procedures are rare.

Key insights

• Binary safety metrics are insufficient; LLMs commonly exhibit an "intermediate failure mode" by disclosing detailed (L2+) but not fully executable (L3) information, which still holds value for misuse.
• LLM safety behavior is system- and context-dependent, with disclosure rates varying significantly across different models, elicitation strategies (e.g., Academic Framing most effective on average), and biomedical risk domains (e.g., Safety domain most vulnerable).
• Effective safeguards must move beyond simple refusal to a granular assessment of information actionability, considering the entire deployment stack and domain-grounded adversarial testing.
