Gemini 3.1 Pro Launches as Google’s New Core Reasoning Model: What It Offers?

Key Highlights:

  • The model more than doubles reasoning performance over Gemini 3 Pro on ARC-AGI-2.
  • Gemini 3.1 Pro is rolling out across consumer, developer, and enterprise products.
  • The release strengthens Google’s push into advanced reasoning and agentic workflows.

Google has released Gemini 3.1 Pro, an upgraded AI model designed to handle complex reasoning tasks across science, research, engineering, and creative work. The model is now rolling out across Google’s consumer apps, developer tools, and enterprise platforms, marking a major step forward in the Gemini 3 series.

Gemini 3.1 Pro is the core intelligence powering recent advances in Gemini 3 Deep Think. With this release, Google is bringing those gains into everyday applications used by developers, businesses, and consumers.

What is Gemini 3.1 Pro, and why does it matter?

Gemini 3.1 Pro is positioned as a smarter baseline model for tasks where simple answers fall short. It focuses on advanced reasoning, logic discovery, and synthesis rather than quick responses.

On ARC-AGI-2, a benchmark that tests whether AI systems can solve entirely new logic patterns, the new model achieved a verified score of 77.1%. That result represents more than double the reasoning performance of Gemini 3 Pro, according to Google.

The benchmark result signals progress in general problem-solving, especially in scenarios where models must adapt without prior examples.

Where is Gemini 3.1 Pro available today?

Google is shipping Gemini 3.1 Pro broadly, starting in preview. Developers can access it through the Gemini API in Google AI Studio, Gemini CLI, Android Studio, and Google’s agentic development platform, Antigravity.

Enterprise users can use Pro models via Vertex AI and Gemini Enterprise. For consumers, the model is rolling out in the Gemini app and NotebookLM.

Users on Google AI Pro and Ultra plans will see higher usage limits in the Gemini app. NotebookLM access to Gemini 3.1 Pro is also limited to Pro and Ultra subscribers.

What can Gemini 3.1 Pro actually do?

Gemini 3.1 Pro is built for tasks that require layered thinking and structured outputs. Google highlights use cases such as generating clear visual explanations, synthesizing complex datasets into a single view, and supporting creative workflows.

One example is code-based animation. Gemini 3.1 Pro can generate animated SVGs directly from text prompts. Because these animations are created in code, they remain sharp at any scale and use smaller file sizes than traditional video.

What comes next?

Google says the preview phase will help validate improvements before general availability. The company plans to push further into agentic workflows, where AI systems can plan and execute multi-step tasks.

For now, Gemini 3.1 Pro sets a new reasoning baseline across Google’s AI stack, with broader access expected in the coming months.
