Gemini 2.5 Flash Lite model profile

Evidence snapshot:

Gemini 2.5 Flash Lite is a Google model profile with a 1,048,576-token context window. The dated catalog snapshot records text, image, file, audio, video modalities and interfaces for audio input, file input, prompt caching, reasoning controls, structured output.

Gemini 2.5 Flash-Lite is a lightweight reasoning model in the Gemini 2.5 family, optimized for ultra-low latency and cost efficiency. It offers improved throughput, faster token generation, and better performance across common benchmarks compared to earlier Flash models. By default, "thinking" (i.e. multi-pass reasoning) is disabled to prioritize speed, but developers can enable it via the Reasoning API parameter to selectively trade off cost for intelligence.

Gemini 2.5 Flash Lite is a reference profile: Google publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.

Gemini 2.5 Flash Lite 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 Lite accepts text, image, file, 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 $0.05 input and $0.2 output per million tokens. Cached input is $0.005 per million tokens.

The 2026-09-06 snapshot includes AutoExacto results for 4 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 Lite ranked #27 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.

Profile data was reviewed for the 2026-09-06 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated.

When to pick Gemini 2.5 Flash Lite

Gemini 2.5 Flash Lite 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 cost is the binding constraint. At $0.05 in and $0.2 out per 1M tokens, combined token price sits in the cheapest quarter of the 146 models publishing both rates in this snapshot.
  • 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.
  • 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.
