The most crushing defeat for OpenAI I did not expect Gemini 3 Pro to be SOTA on WeirdML WeirdML has been an OpenAI stronghold for quite some time. https://x.com/scaling01/status/1991154001283358992
Gemini 3 Pro takes the crown on LisanBench – it scores 2.2x higher than GPT-5 while using 2.4x fewer reasoning tokens – it has the highest score on 23 out of 50 words – Grok-4 is the only model that can keep up https://x.com/scaling01/status/1990845163652993166
The Artificial Analysis leaderboard shows Gemini 3 at 73%, GPT-5.1 at 70%, and Kimi at 67% – minor differences. On our leaderboard, Gemini is 47%, GPT-5.1 is 38%, and Kimi is 27% – Gemini 3 is substantially more capable on hard benchmarks. https://x.com/hendrycks/status/1991188104804208736
