Google announces Gemini 3.1 Pro, says it's better at complex problem-solving

Another day, another Google AI model. Google has really been pumping out new AI tools lately, having just released Gemini 3 in November. Today, it's bumping the flagship model to version 3.1. The new Gemini 3.1 Pro is rolling out (in preview) for developers and consumers today with the promise of better problem-solving and reasoning capabilities.

Google announced improvements to its Deep Think tool last week, and apparently, the "core intelligence" behind that update was Gemini 3.1 Pro.
