Gemini 3.1 Flash Lite

by Google

Gemini 3.1 Flash Lite is the newest-generation Lite model from Google, pairing low latency with multimodal capability and an extended reasoning mode. With a 1M-token context window and support for text, images, and PDFs, it handles translation, data extraction, and lightweight agentic workflows efficiently. The model supports a thinking mode for tougher classification and extraction tasks, function calling for tool integration, and structured outputs for programmatic use. It works well for document processing, entity extraction, and routing queries to specialized models based on complexity. Versus Gemini 2.5 Flash Lite, this generation offers improved efficiency and reasoning, while staying more economical than the full Gemini 3.1 Flash. Use it for high-frequency, cost-constrained tasks where speed and multimodal understanding matter.
