- Gemini 3.1 Pro: #1 on the intelligence index, with caveats
Gemini 3.1 Pro launched February 19 with a 77.1% ARC-AGI-2 score (more than double its predecessor), #1 on the Artificial Analysis Intelligence Index, 1M token context, and $2/$12 per million pricing. The caveats: preview status and notably high verbosity. Where it fits in the frontier developer choice.
