It’s time we took ‘Chem’ out of ‘Chem-Bio’ threats

AI safety evaluations should treat chemical security as its own distinct domain rather than grouping it under biological threats, according to a post by LessWrong. The author, a chemistry PhD, argues that while the two fields overlap, assuming biosecurity evaluations cover chemical risks may leave chemistry-specific failure modes overlooked. This distinction is especially critical as AI models move beyond text to multimodal data, such as interpreting spectra or microscopy images, which could reveal dangerous capabilities that text-based tests miss.
