The new default model for Gemini and Google Search's AI Mode is Gemini 3 Flash, a speed-optimized version of Google's recently announced flagship model that retains frontier-level intelligence.

The specifics:

Gemini 3 Flash, at ¼ the price and 3x the speed, matches and even surpasses 3 Pro on a variety of benchmarks.

Flash got 33.7% on Humanity's Last Exam, closely equal GPT-5.2's 34.5% and triple the 11% from its predecessor.

3 Flash is now the default setting for both the Gemini App and Google Search's AI Mode, which combines quick, enhanced reasoning with real-time web results.

Contrary to popular belief, Gemini 3 Flash feels like a larger deal than 3 Pro because it offers an unparalleled combination of speed and intelligence at prices that are much lower than those of the competitors. Flash appears to be another factor contributing to Google's ongoing erosion of OpenAI's market dominance.
