Gemini 2.5 Flash model profile
Evidence snapshot:
Gemini 2.5 Flash is a Google model profile with a 1,048,576-token context window. The dated catalog snapshot records file, image, text, audio, video modalities and interfaces for audio input, file input, prompt caching, reasoning controls, structured output.
Gemini 2.5 Flash is Google's state-of-the-art workhorse model, specifically designed for advanced reasoning, coding, mathematics, and scientific tasks. It includes built-in "thinking" capabilities, enabling it to provide responses with greater accuracy and nuanced context handling. Additionally, Gemini 2.5 Flash is configurable through the "max tokens for reasoning" parameter, as described in the documentation (
Gemini 2.5 Flash is a reference profile: Google publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.
Gemini 2.5 Flash is an independent knowledge profile. It does not claim that Kendr hosts the model, quote a Kendr customer price, promise API availability, or advertise a Kendr routing receipt.
Gemini 2.5 Flash accepts file, image, text, audio, and video and returns text. The snapshot records audio input, file input, prompt caching, reasoning controls, structured output, text generation, tool calling, video input, vision, and web search pricing as capabilities or interfaces.
The dated reference snapshot lists $0.15 input and $1.25 output per million tokens. Cached input is $0.015 per million tokens.
The 2026-09-06 snapshot includes 7 Design Arena categories and AutoExacto results for 5 provider observations. Publisher-reported launch results are labeled and are not presented as Kendr measurements; scores from different suites are not treated as interchangeable.
Gemini 2.5 Flash ranked #31 in the cited trailing-7-day third-party catalog usage dataset as of 2026-09-06. Observed within the cited trailing-7-day third-party catalog usage dataset; this is not global AI market share.

When to pick Gemini 2.5 Flash
Gemini 2.5 Flash is a reference profile: Google publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.
Each condition below is derived from this model's own values in the 2026-09-06 snapshot, compared only against models publishing the same field.
- Reach for it when a whole corpus has to fit in one prompt. The 1.05M-token context window is in the top quarter of the 163 models publishing a limit here, so long documents can go in whole rather than chunked.
- Reach for it when the input includes images. The snapshot records image input, so screenshots, scans, and diagrams can be sent directly instead of described.
- Reach for it when the input is speech. The snapshot records audio input, so recordings can go to this route rather than being transcribed first.
- Reach for it when the model has to call tools. Tool calling is recorded in the snapshot, so this route can drive an agent loop rather than only answer in prose.
- Look elsewhere when you need to call it through Kendr today. This is a research reference profile with no Kendr alias. The facts and evidence here are published for comparison; the model is not routable on Kendr.
