Google has released Gemini 3.1 Pro, an upgraded core intelligence model it says improves reasoning and complex problem-solving across science, research and engineering use cases. The company is rolling out the model across its consumer, developer and enterprise products starting February 20.
“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,” the company said in a statement.
“We are shipping 3.1 Pro across our consumer and developer products to bring this progress in intelligence to your everyday applications.”
Gemini 3.1 Pro is available in preview for developers through the Gemini API in Google AI Studio, Gemini CLI, Google Antigravity and Android Studio. Enterprise customers can access it through Vertex AI and Gemini Enterprise. Consumers can use the model through the Gemini app and NotebookLM, with higher usage limits for Google AI Pro and Ultra subscribers.
Building on the Gemini 3 series, the company said 3.1 Pro improves baseline reasoning for complex tasks.
On ARC-AGI-2, a benchmark that measures a model’s ability to solve new logic patterns, the model achieved a verified score of 77.1%, which the company said is more than double the reasoning performance of Gemini 3 Pro.
“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,” the company said. It added that the model can generate visual explanations, synthesise data into a single view and support creative workflows.
The company also highlighted code-based animation capabilities. According to the statement, 3.1 Pro can generate website-ready animated SVGs directly from text prompts. Because the animations are built in code rather than pixels, they remain scalable and have smaller file sizes than traditional video formats.
Google said it is releasing 3.1 Pro in preview to validate updates and continue work on “ambitious agentic workflows” before making the model generally available.
“Since releasing Gemini 3 Pro in November, your feedback and the pace of progress have driven these rapid improvements,” the company said. “We can’t wait to see what you build and discover with it.”
Google recently also introduced music generation in the Gemini app, rolling out its latest model, Lyria 3, in beta. It enables users to create 30-second tracks using text prompts, images or videos.
