Gemini 2.5 Flash is Google's June 2025 workhorse model with a 1M token context, and it is deprecated, so treat it as a model to migrate off. OpenRouter listed it on 17 June 2025 with a context of 1,048,576 tokens at $0.30 per million input tokens and $2.50 per million output tokens on its cheapest route, as listed on 5 November 2026. Google's own page matches for text, image and video input, charges $1.00 for audio input, and counts thinking tokens as output. The Gemini API has a free tier for it. Google says the model is no longer selectable in AI Studio, and that from 1 December 2026, at the earliest, requests route to Gemini 3.5 Flash-Lite and are billed at that model's rates, which can change both quality and cost. It accepts text, images, audio, video and files and returns text. We have not run it ourselves. We would use it only to keep a working pipeline alive until you move to Gemini 3.8 Flash or a similar current model. Figures come from Google's pricing and deprecations pages, and from OpenRouter's list.
