About this model
Gemini 3.5 Flash Lite is an AI model from Google DeepMind, made available through the API on July 21, 2026. It can read up to 1,048,576 tokens in one request, roughly 1,966 pages of text, and write up to 65,536 tokens in a single answer. Besides text, it accepts images, video, files such as PDFs and audio as input.
Through the API it costs $0.30 per million input tokens and $2.50 per million output tokens. Its pricing sits in the middle of the market.
It supports extended reasoning: it can "think" step by step before answering, which helps on maths, code and complex questions. It can call tools and functions, so developers can connect it to search, databases or other software.
