Gemini 2.5 Flash-Lite

Gemini 2.5 Flash-Lite is our most balanced Gemini model, optimized for low latency use cases. It comes with the same capabilities that make other Gemini 2.5 models helpful, such as the ability to turn thinking on at different budgets, connecting to tools like Grounding with Google Search and code execution, multimodal input, and a 1 million-token context length.
