What is Gemini 3.1 Pro?

Gemini 3.1 Pro is Google's upgraded core intelligence model, designed for tasks where a simple answer isn't enough. Building on the Gemini 3 series, it represents a significant step forward in core reasoning, offering a smarter, more capable baseline for complex problem-solving. The model is rolling out across consumer and developer products, including the Gemini API, Vertex AI, the Gemini app, and NotebookLM.

Who it's for

• Developers – who need a preview of advanced reasoning capabilities via the Gemini API, Google AI Studio, Gemini CLI, Google Antigravity, and Android Studio.
• Enterprises – looking to integrate smarter problem-solving into their workflows through Vertex AI and Gemini Enterprise.
• Consumers – who want to tackle complex tasks in the Gemini app or NotebookLM, from synthesizing data to creative projects.

Key features

Advanced reasoning benchmarks

Gemini 3.1 Pro achieved a verified score of 77.1% on ARC-AGI-2, a benchmark that evaluates a model's ability to solve entirely new logic patterns. This is more than double the reasoning performance of 3 Pro, making it a powerful tool for tasks requiring deep analytical thinking.

Code-based animation

The model can generate website-ready, animated SVGs directly from a text prompt. Because these are built in pure code rather than pixels, they remain crisp at any scale and maintain incredibly small file sizes compared to traditional video.

Complex system synthesis

Gemini 3.1 Pro utilizes advanced reasoning to bridge the gap between complex APIs and user-friendly design. It can build live dashboards, such as configuring a public telemetry stream to visualize the International Space Station's orbit.

Interactive design

The model codes complex 3D experiences, like a starling murmuration, where users can manipulate the flock with hand-tracking and listen to a generative score that shifts based on the birds' movement. This provides a powerful way to prototype sensory-rich interfaces.

What stands out

"3.1 Pro is a smarter, more capable baseline for complex problem-solving."

This isn't just an incremental update—it's a doubling of reasoning performance on rigorous benchmarks. The model's ability to synthesize data, explain complex topics, and create interactive code-based experiences makes it a versatile tool for professionals and creators alike. Whether you're building a live aerospace dashboard or translating literary themes into functional code, Gemini 3.1 Pro applies advanced reasoning to practical, real-world challenges.

Worth checking out if…

You need a model that goes beyond simple answers and can handle complex reasoning, data synthesis, or creative coding. It's ideal for developers prototyping agentic workflows, enterprises seeking smarter AI integration, or anyone who wants to bring ambitious projects to life with code-based animations and interactive designs.
