The Refusal Was Not the Safety Test
A 32-model audit found that conversational refusal rates did not predict a function-aware computational risk score for generated protein sequences.
Summary
A 32-model audit found that conversational refusal rates did not predict a function-aware computational risk score for generated protein sequences.
Researchers introduced SPIKE-Bench, a preprint evaluation suite pairing 631 toxin-design prompts with three computational checks: whether a model complied, whether its output looked biologically plausible, and whether prediction tools flagged toxin-like function. Across 32 language models, the authors report that most systems complied with many requests and that their Functional Harmfulness Rate reached as high as 50.7 percent, while refusal rate was not a reliable proxy. A specialized classifier reduced the predicted risk signal in their tests. The work measures model outputs with computational predictors; it does not demonstrate successful synthesis, laboratory toxicity or real-world harm.
