Gemini 2.5 Pro Preview 06-05
About this model
Gemini 2.5 Pro Preview 06-05 is an AI model from Google DeepMind, made available through the API on June 5, 2025. 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 files such as PDFs, images and audio as input.
Through the API it costs $1.25 per million input tokens and $10 per million output tokens. It is among the more expensive models we track, a price usually reserved for the most capable, flagship-class models.
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.
