Gemini 3.7 Flash Is Available on FastRouter

Google's Gemini 3.7 Flash is now available through FastRouter. It's a natively multimodal model in the Gemini 3 series, built for fast agentic workflows and complex reasoning across text, images, video, audio, and PDFs, and it's accessible through the same FastRouter endpoint with no configuration changes required.

What's in Gemini 3.7 Flash

Gemini 3.7 Flash supports a 1,048,576 token context window and produces text-only output from multimodal input. It supports advanced tools including function calling, file search, computer use, and structured outputs, along with configurable thinking levels for requests that call for more deliberate reasoning rather than the fastest possible response. It's built for production use through the Gemini API, balancing speed, cost efficiency, and multimodal understanding.
