Gemini 2.5 Flash Lite

by Google

Released 12 days after Gemini 2.5 Pro · All Google releases

Gemini 2.5 Flash Lite is Google's most cost-efficient Gemini 2.5 model, built for high-throughput tasks where speed and affordability matter. With a 1M-token context window, it processes text, images, and PDFs, making it well suited to large-scale data extraction, translation, and document processing. The model handles entity classification, PDF summarization, and lightweight agentic workflows where a smaller model can route queries to more powerful peers. It supports function calling, structured outputs, code execution, and an optional thinking mode for tougher reasoning without the latency of larger models. Compare it to Gemini 2.5 Flash for richer general-purpose capability, or to Gemini 3.1 Flash Lite for the newest generation with improved reasoning efficiency.
