Evolution instead of revolution – that’s ultimately what Google’s brand-new AI model Gemini 3.1 Pro delivers. As the numbering already suggests, it’s a minor update to Google’s best LLM, Gemini 3 Pro, and will soon be rolled out to all paying Google AI Pro and Ultra subscribers. The new model is intended to offer significant progress especially on demanding tasks, but currently this LLM doesn’t surpass Anthropic’s top model (Claude Opus 4.6) on Arena.ai, though it does on Artificial Analysis.
