Google released Gemini 3.1 Pro, pitched as a step forward in core reasoning over Gemini 3 Pro rather than a full-generation model. The company had previously versioned Gemini updates in increments of 0.5; this was the first Gemini release to use a 0.1 step, a naming choice that itself signalled an incremental rather than flagship upgrade.
Google reported that 3.1 Pro scored a verified 77.1% on the ARC-AGI-2 benchmark, which it described as more than double Gemini 3 Pro’s reasoning performance on the same test. The model added capabilities such as generating animated SVGs and interactive designs, and Google positioned it as the new baseline intelligence behind the company’s products, folding in the reasoning improvements that had debuted the previous week in an upgrade to Gemini 3 Deep Think, its specialised high-effort reasoning mode.
Availability was broad from launch: preview access for developers through the Gemini API, Google AI Studio, Gemini CLI, Google Antigravity and Android Studio; enterprise access via Vertex AI and Gemini Enterprise; and consumer access through the Gemini app and NotebookLM, with higher usage limits for Google AI Pro and Ultra subscribers.
