Gemini 2.5 Pro is Google's June 2025 reasoning model with a context of 1,048,576 tokens, and it is now deprecated, so it only matters for code that still calls it. OpenRouter listed it on 17 June 2025 and shows $1.25 per million input tokens and $10 per million output tokens on its cheapest route, as listed on 5 November 2026. Google's pricing page agrees for prompts up to 200k tokens, then charges $2.50 and $15 above that, and thinking tokens count as output. A free tier exists in the Gemini API. The catch is the retirement: Google says the model is no longer selectable in AI Studio, and from 1 December 2026, at the earliest, requests route to Gemini 3.8 Flash and are billed at that model's rates. That changes behaviour and cost without a code change, so pin a current model now. It takes text, images, audio, video and files in and returns text. We have not run it ourselves. We would not start new work on it. Figures come from Google's pricing and deprecations pages, and from OpenRouter's list.
