# Google Gemini 3.6 Flash API

> Gemini 3.6 Flash is a multimodal reasoning model in Google's Gemini 3 Flash line, released in July 2026 alongside 3.5 Flash-Lite. Google describes it as delivering frontier-level intelligence at higher speed for real-world agentic work, excelling at code generation, agentic execution and spatial reasoning, and particularly effective in rapid agentic loops with repeated coding iterations. It is Google's recommended replacement for the Gemini 3 Flash preview; 3.7 Flash and 3.8 Flash followed it.
