Back to changelog
Gemini 3.5 Flash , Google’s latest Flash-tier model, is now rolling out on GitHub Copilot. In our early testing, Gemini 3.5 Flash delivers near-Pro coding quality at Flash-tier speed and cost with strong tool use, fast response times, and high cache efficiency that make it well-suited for fast, iterative agentic coding workflows.
Note, that while this model is launching with a 14X premium request multiplier, pricing is tentative and subject to change.
