Google DeepMind Launches Gemini 3.1 Pro with Significantly Improved Overall Intelligence

Gemini 3.1 Pro Is Here

Google DeepMind announced Gemini 3.1 Pro on February 19, 2026, with significantly improved overall intelligence — enabling the model to solve tougher, more complex problems than its predecessor.

Rollout Details

Gemini 3.1 Pro is rolling out in the Gemini App for Google AI Pro and Ultra subscribers. It is also available exclusively in NotebookLM for the same subscriber tiers. Developers can access it in preview via the API through Google AI Studio.

What Changed

The update represents a broad improvement in general reasoning, coding, and multi-step problem solving. Google DeepMind framed it as a meaningful step up in everyday intelligence compared to Gemini 3 Pro, complementing the specialized scientific reasoning capabilities introduced in the Gemini 3 Deep Think upgrade earlier in February — which achieved an unprecedented 84.6% on ARC-AGI-2.

Competitive Backdrop

The announcement lands in the same week as Anthropic's Claude Sonnet 4.6 release, underscoring the breakneck pace of model releases across the top AI labs in early 2026.
