Summary
Gemini 3 Flash Preview is the preview release that opened Google's Gemini 3 Flash line, at $0.5 per million input tokens and $3 per million output tokens. Four stable Flash models have landed since; the three most recent cost $0.75 / $3.75 with the same limits.
This is a preview model, listed with a December 2025 update. It takes text, image, video, audio and PDF input within a 1,048,576-token context window and returns up to 65,536 output tokens, with caching, code execution, computer use, file search, function calling, Maps and search grounding, structured outputs, thinking, URL context and the Batch API. The Live API is not supported.
Google's deprecation history shows preview models being shut down on shorter timelines than stable releases. Gemini 3.6, 3.7 and 3.8 Flash are stable and carry the same limits, which makes the preview hard to justify for new work.
No deprecation has been announced for this model ID.
