from the latest-and-greatest dept.)
Google has [1]introduced Gemini 3.1 Pro, a reasoning-focused upgrade [2]aimed at more complex problem-solving . 9to5Google reports:
> This .1 increment is a first for Google, with the past two generations seeing .5 as the mid-year model update. (2.5 Pro was first announced in March and saw further updates in May for I/O.) Google says Gemini 3.1 Pro "represents a step forward in core reasoning." The "upgraded core intelligence" that debuted last week with Gemini 3 Deep Think is now available in Gemini 3.1 Pro for more users. This model achieves an ARC-AGI-2 score of 77.1%, or "more than double the reasoning performance of 3 Pro."
>
> This "advanced reasoning" translates to practical applications like when "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." 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.
