Gemini 3.1 Pro: A smarter model for your most complex tasks
Source: Dev.to

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.
Rolling out today
- For developers – preview via the Gemini API in Google AI Studio, Gemini CLI, our agentic development platform Google Antigravity, and Android Studio
- For enterprises – available 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. It is a smarter, more capable baseline for complex problem‑solving, 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 verified score of 77.1 %, more than double the reasoning performance of 3 Pro.
Intelligence applied
3.1 Pro is designed for tasks where a simple answer isn’t enough, taking advanced reasoning and making it useful for your hardest challenges. This improved intelligence can help in practical applications—whether you need a clear, visual explanation of a complex topic, a way to synthesize data into a single view, or a creative project brought to life.
- Code‑based animation – generate website‑ready, animated SVGs directly from a text prompt. Because they’re pure code rather than pixels, they stay crisp at any scale and have tiny file sizes compared with traditional video.
- Complex system synthesis – bridge the gap between intricate APIs and user‑friendly design. In one example, the model built a live aerospace dashboard, configuring a public telemetry stream to visualize the International Space Station’s orbit.
- Interactive design – code a complex 3D starling murmuration that users can manipulate with hand‑tracking, accompanied by a generative score that shifts based on the birds’ movement. This offers researchers and designers a powerful way to prototype sensory‑rich interfaces.
- Creative coding – translate literary themes into functional code. When asked to build a modern personal portfolio for Emily Brontë’s Wuthering Heights, the model reasoned through the novel’s atmospheric tone to design a sleek, contemporary website that captures the protagonist’s essence.
What’s next
Since releasing Gemini 3 Pro in November, your feedback and the pace of progress have driven these rapid improvements. We are releasing 3.1 Pro in preview today to validate these updates and continue advancing ambitious agentic workflows before a general availability launch.
Starting today, Gemini 3.1 Pro in the Gemini app rolls out with higher limits for users on the Google AI Pro and Ultra plans. It is also available on NotebookLM exclusively for Pro and Ultra users. Developers and enterprises can access 3.1 Pro now in preview via the Gemini API in AI Studio, Antigravity, Vertex AI, Gemini Enterprise, Gemini CLI, and Android Studio.
We can’t wait to see what you build and discover with it.
