How 4 builders are using Google Gemini 3.8 Flash

Gemini 3.8 Flash is our most intelligent workhorse model, delivering significant improvements from 3.7 Flash across software engineering, agentic tasks, and critical, multistep reasoning in specialized domains. These performance gains stem from a core design choice: 3.8 Flash works harder. On complex tasks, it exhibits greater diligence — executing extra reasoning steps and calling tools iteratively to land a more accurate output.

Builders have been creating with Gemini 3.8 Flash since we launched it and new audio models this month. From developing simulations to testing visual reasoning, check out some of the coolest builds and experiments from the community so far.
