Google has launched Gemini 3. 1 Pro, a significant update to its flagship AI model focused on sharper reasoning and better handling of complex, multi-step tasks. The model is rolling out today across the Gemini app, NotebookLM, and developer platforms including Google AI Studio, Vertex AI, and Antigravity.
Google Gemini 3. 1 Pro features: What the upgrade actually brings
This is Google’s first-ever . 1 increment—previous cycles used . 5 as the mid-year refresh. The naming signals a focused intelligence upgrade rather than a broad feature expansion. At its core, 3. 1 Pro brings the advanced reasoning engine introduced in Gemini 3 Deep Think last week to a much wider audience.
Google describes the model as built for situations where “a simple answer isn’t enough.” In practice, that means handling things like synthesising large datasets into a single view, generating animated SVGs directly from a text prompt, or working through layered technical and scientific problems.
The animated SVG capability is a neat example—outputs are built in pure code rather than pixels, meaning they stay crisp at any scale with tiny file sizes compared to traditional video.
Google Gemini 3. 1 Pro vs OpenAI GPT and Anthropic Claude: What the numbers say
The headline figure is a 77. 1% score on ARC-AGI-2, a benchmark that tests abstract reasoning on entirely new logic patterns. That’s more than double Gemini 3 Pro’s score—a meaningful jump. Elsewhere, 3. 1 Pro scores 94. 3% on GPQA Diamond (scientific knowledge), 80. 6% on SWE-Bench Verified (agentic coding), and 85. 9% on BrowseComp (agentic search). On LiveCodeBench Pro’s competitive coding Elo, it sits at 2887—notably ahead of rivals.
Google Gemini 3. 1 Pro: How to access it right now
Gemini 3. 1 Pro is launching in preview while Google validates performance, particularly around agentic workflows. Consumers can access it through the Gemini app and NotebookLM, with higher usage limits for Google AI Pro and Ultra subscribers. Developers get access via the Gemini API in Google AI Studio, Gemini CLI, Antigravity, Vertex AI, Gemini Enterprise, and Android Studio. General availability is expected soon.
