teortaxesTex · x · 2026-10-17
teortaxesTex maps the best public models per lab on the Artificial Analysis Intelligence Index: Claude Opus 4.5, Muse, GPT-5.2, and Gemini 4 form the top tier (53-56), with Grok 4.1, GLM-5.3, and MiniMax trailing at 44-46, and open models like DeepSeek, Mistral, and Kimi far behind at 26-39. He expects xAI to make the top 5 soon and notes no "American open-weight renaissance" yet — Mistral sits within margin of error of the best US open model.
