- FrontierCode 2.0 (Cognition, real-world engineering incl. maintainer-merge judgments): tops the chart at 19.7%, ahead of DeepSeek V4.1 Flash (19.3%), GLM-5.3 (17.8%), Kimi K3 (17.3%).
- Terminal-Bench 4.0: 41% first, vs GLM-5.3 40%, DeepSeek V4.1 Flash 1017 31%, Kimi K3 21%.
- Surge Code blind human preference: 64% wins over GLM-5.3 and Kimi K3, but only 22% vs Claude Opus 5.5.
