About Gemini 3.8 Flash
Gemini 3.8 Flash is the latest Flash generation from Google (released September 2026), built for long-running coding, agent workflows and complex reasoning: 1M-token context, up to 64K output, image input, and a dynamic thinking budget that answers simple questions fast and thinks longer on hard ones. Fully OpenAI-API compatible: set model to gemini-3.8-flash. Priced below the Google list price on both input and output.
Use cases
A 1M context holds a whole repository plus long conversation history, ideal for agents with many tool calls.
The dynamic thinking budget returns simple requests quickly and thinks more on hard ones, with no manual tiering.
Image input is supported, so screenshot understanding and chart questions use the same endpoint.
How to choose
Pick 3.8 for the latest generation; stay on gemini-3.7-flash (same price) if your prompts are tuned for it; use the four gemini-3.6-flash tiers when you want manual control of the thinking budget.
