Gemini 3.6 Flash is a generally available model that Google's documentation positions as sustained frontier-level intelligence for the agentic era, optimized for higher speed and lower cost — the docs say it delivers stronger performance on complex agentic and multimodal tasks while reducing token usage, at a lower price point than 3.5 Flash.
- It supports thinking and the full built-in tool suite including Computer Use, takes text, image, video, and audio input across a 1M-token context window with 65,536 output tokens, and adds an API change the model page flags: temperature, top_p, and top_k are deprecated and ignored from this generation onward.
- Synthorai serves it through its OpenAI-compatible chat endpoint.
