New Framework Quantifies CBRN Risk Upsurge from Frontier LLMs
Researchers introduce the Threshold Exceedance Criteria (TEC) to measure whether access to cutting‑edge language models gives non‑experts material ability to devise chemical, biological, radiological or nuclear attacks. In a large‑scale study, only radiological planning showed statistically significant uplift, informing tighter deployment safeguards. The method separates generative and revisionist assistance and sets clear baselines for future safety assessments.
