Gemini 3.1 Pro: A smarter model for your most complex tasks

Last week, we released a major update to Gemini 3 Deep Think to solve modern challenges across science, research and engineering. 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. Starting today, 3.1 Pro is rolling out: For developers in preview via the Gemini API in Google AI Studio , Gemini CLI , our agentic development platform Google Antigravity and Android Studio For enterprises in Vertex AI and Gemini Enterprise For consumers via the Gemini app and NotebookLM Building on the Gemini 3 series, 3.1 Pro represents a step forward in core reasoning. 3.1 Pro is a smarter, more capable baseline for complex problem-solving. This is reflected in our progress on rigorous benchmarks. On ARC-AGI-2, a benchmark that evaluates a model’s ability to solve entirely new logic patterns, 3.1 Pro achieved a
