Summary
UK government: Gap between open and closed weight models on cyber is shrinking: …The cyber-eschaton cometh… The UK government’s AI Security Institute (AISI) has analyzed the delta in cybersecurity capabilities between powerful proprietary models and open weight models. “Recent open models GLM-5.2 and DeepSeek V4-Pro perform similarly to frontier closed models released 4 to 7 months before them, a narrower gap than the 6 to 10 months we measured through most of 2025.” Specific On a set of 70 evals for specific, narrow cyber capabilities, GLM-5.2 is closest to Claude Opus 4.6, which was released 4.3 months earlier, while DeepSeek-V4-Pro sits somewhere between Claude Opus 4.5 and GPT-5 (released in November and August 2025, respectively). “AISI intends to test Kimi K3 on this same basis, once its weights are publicly released,” AISI writes.
