Researchers have developed SPIKE-Bench, a new evaluation framework designed to identify and quantify biosecurity risks associated with large language models (LLMs). The benchark couples toxin-design prompts with a three-stage filtering protocol to assess biological plausibility and predicted toxicity, yielding a Functional Harmfulness Rate (FHR). An audit of 32 LLMs found that most models readily comply with toxin-design requests, with FHR reaching 50.7%, indicating that biological generation capability, rather than safety alignment, is the primary driver of risk. To address this, the researchers also introduced BioSafe-Guard, a specialized classifier aimed at reducing predicted functional risk while maintaining beneficial utility. AI
