README

Gemini 2.5 Flash Lite is Google's lighter 2.5 model, optimized for low latency and lower cost while still keeping the multimodal and tool-use foundations of the broader Gemini 2.5 family.

Google describes Gemini 2.5 Flash Lite as a balanced model optimized for low-latency use cases.
It keeps key Gemini 2.5 capabilities such as multimodal input, grounding with Google Search, code execution, and a 1 million-token context length.
It is a strong fit for high-volume assistants, routing layers, background automation, and other workloads where throughput and cost matter more than frontier depth.
