UK and US evaluators publish Kimi K3 cyber results
UK AISI and NIST's CAISI found Kimi K3 stronger than GLM-5.2 but below leading closed models on exploit development and a 32-step cyber range. It achieved arbitrary code execution on zero of 41 ExploitBench samples.
Why it matters: A government evaluation separates an open model's general release claims from concrete offensive-cyber capability under documented tasks and token limits.
