According to Demis Hassabis on X, Google DeepMind launched Gemini 3.1 Pro with major gains in core reasoning and problem solving, scoring 77.1% on the ARC-AGI-2 benchmark, more than double Gemini 3 Pro’s performance; the model is rolling out in Gemini App and Antigravity today (source: @demishassabis). As reported by Hassabis, these improvements signal stronger generalization and few-shot capabilities, which can translate into higher accuracy for enterprise agents, code assistants, and automated analytics workflows. According to the announcement, immediate availability in product surfaces enables faster A/B testing, developer adoption, and monetization for partners integrating Gemini 3.1 Pro via app ecosystems.
