Google Releases Gemini 3.1 Pro

Google announced the release of Gemini 3.1 Pro, a “step forward in core reasoning” for its most powerful AI model. This is the first time that Google has incremented a Gemini AI model by a 0.1 step; previous upgrades were 0.5 releases.

“Gemini 3.1 Pro is great for super complex tasks like visualizing difficult concepts, synthesizing data into a single view, or bringing creative projects to life,” Google CEO Sundar Pichai tweeted. “We’re shipping 3.1 Pro across our consumer and developer products to bring this underlying leap in intelligence to your everyday applications right away.”

Gemini 3.1 Pro is based on a Gemini 3 Deep Think update that Google delivered last week, allowing the model to “solve modern challenges across science, research, and engineering.” In this iteration, the new capabilities are available to a much wider audience, allowing users to access advanced reasoning in their creative tasks. Or, as Google puts it more succinctly, “it’s a smarter model for your most complex tasks.”

“Gemini 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,” Google explains. “This improved intelligence can help in practical applications, whether you’re looking for a clear, visual explanation of a complex topic, a way to synthesize data into a single view, or bringing a creative project to life.”

Google Gemini 3.1 Pro is rolling out now to consumers in the Gemini app and NotebookLM (and with higher limits for users with the Google AI Pro and Ultra plans), to enterprises via Gemini Enterprise and Vertex AI, and to developers in preview via the Gemini API in Google AI Studio, Gemini CLI, Google Antigravity, and Android Studio.
