Google's Robby Stein, VP of Product at Google Search, said on X, "Gemini 3.8 Flash has landed in Search." This comes only a couple of weeks after Google brought Gemini 3.7 Flash to AI Mode within Google Search.
This will work in Google Search's AI Mode for Google AI Pro & Ultra subscribers globally. This is a global roll out and if you are a subscriber, you can access it by clicking the plus icon and then selecting the model.
Robby Stein added:
