Gemini 3 Flash

Google Releases Gemini 3 Flash

Google rolled out Gemini 3 Flash, a speed-optimized version of its flagship model that maintains frontier-level intelligence while significantly boosting speed, becoming the new default for Gemini and Google Search AI Mode.

  • Performance: Gemini 3 Flash matches or exceeds 3 Pro across benchmarks at 1/4 the price and 3x the speed
  • Benchmarks: Scored 33.7% on Humanity's Last Exam—triple predecessor's 11%, nearly matching GPT-5.2's 34.5%
  • Default Deployment: Gemini App and Google Search AI Mode now default to 3 Flash, combining real-time web results with fast, improved reasoning
  • Competitive Edge: Unmatched intelligence-speed combo at prices significantly undercutting competition

Why it matters: Gemini 3 Flash feels like a bigger deal than 3 Pro—offering unmatched intelligence and speed at prices that significantly undercut competition. Google continues eating OpenAI's market share, and Flash looks like another reason for that trend to continue.
