Google Begins Rollout of Gemini 3.1 Pro, Its Upgraded Core AI Model

Google reports a 77.1% ARC‑AGI‑2 score that more than doubles the prior 3 Pro’s reasoning.

Overview

  • The release starts with a staged deployment across Google’s developer, enterprise and consumer channels.
  • Developers can access a preview via Google AI Studio, Gemini CLI, the Antigravity agent platform and the Gemini API in Android Studio.
  • Enterprise users can use the model through Vertex AI and Gemini Enterprise as part of the rollout.
  • In the Gemini app, Google AI Pro and Ultra subscribers receive higher usage limits, and NotebookLM offers 3.1 Pro exclusively to those tiers.
  • Google positions the model for advanced problem‑solving, including clearer visual explanations and consolidation of data from multiple sources.
