Google releases Gemini 3.1 Pro: Why is this model better?

“Today, we’re releasing the upgraded core intelligence that makes those breakthroughs possible: Gemini 3.1 Pro. We are shipping 3.1 Pro across our consumer and developer products to bring this progress in intelligence to your everyday applications,” the company said.

Building on the Gemini 3 series, Gemini 3.1 Pro represents a significant leap in core reasoning and complex problem-solving capabilities.

The model has shown marked improvement on rigorous benchmarks.

On ARC-AGI-2 — a benchmark designed to test a model’s ability to solve entirely new logic patterns — Gemini 3.1 Pro achieved a verified score of 77.1%, more than double the reasoning performance of Gemini 3 Pro.
