Article Summaries:

  • Google has rolled out Gemini 3.1 Pro, a preview version of its flagship AI model aimed at improved problem‑solving and reasoning. The update follows last week’s Deep Think tool announcement, which cited Gemini 3.1 Pro as its core engine. Benchmark results show modest gains: the model scored 44.4 % on Humanity’s Last Exam (up from 37.5 % for Gemini 3) and 77.1 % on ARC‑AGI‑2, more than doubling Gemini 3’s 31.1 %. Despite these gains, Gemini 3.1 Pro does not top the Arena leaderboard, trailing Claude Opus 4.6 in text and several models in code.
