Gemini 2.5 Flash Lite is a language model from Google. It ranks #230 of 504 in ModelCap's all-versions archive, with an Index score of 48.0, modeled from public metadata, not measured. Its score range of 38.3–57.7 spans positions #155–#284. It is listed at $0.10 per million input tokens and $0.40 per million output tokens from one provider. It reads up to 1M tokens of context, with no downloadable weights linked in the current source data.

How this position was produced · fused launch placement
No general-family board lists this model yet. Its point estimate is the precision-weighted mean of every channel that spoke for it; each channel’s share is the weight it carried. Independent measurements replace this placement as boards list the model.

Market and catalogue signals · secondary, never the language Index rank
These adoption and deployment observations remain context only. They do not change this model's ModelCap Index score or rank.
The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.
Not yet published: a pinned repository revision, the architecture and model type, a parameter count, safetensors weight metadata, the base model it derives from, a declared licence, a link to the licence terms, admitted benchmark results, results across several capability areas, results from more than one source, a confident match to its benchmark entries, pinned evaluation dataset versions.
A metadata completeness and deployability index—not a safety certification, quality grade, or production-readiness claim.
Market Gravity uses OpenRouter’s full-catalogue popularity order. Sparse Vercel top-ten observations appear only when published and do not affect the score.

Benchmark leaderboards featuring Gemini 2.5 Flash Lite
How does Gemini 2.5 Flash Lite rank among AI models?
Gemini 2.5 Flash Lite is a superseded version and is not on the current board as of 6 November 2026. Its archive position, where one exists, is shown on the page; the newer version carries the current rank.
How much does Gemini 2.5 Flash Lite cost per 1M tokens?
Gemini 2.5 Flash Lite is listed at $0.10 per 1M input tokens and $0.40 per 1M output tokens as of 6 November 2026. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $0.40 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.
What is the context window of Gemini 2.5 Flash Lite?
Gemini 2.5 Flash Lite has a published context window of 1M tokens (1,048,576). The snapshot lists a 65,535 token catalogue-declared route output cap. OpenRouter catalogue or provider-endpoint declaration. Limits can vary by provider and prompt length; a model-wide maximum has not been independently verified. The providers table lists each endpoint's context limit.
Is Gemini 2.5 Flash Lite open-weight?
No linked weights. No downloadable model weights are linked in the current source data. This does not identify every API or chat product that offers the model.
Which API providers serve Gemini 2.5 Flash Lite?
One provider serves Gemini 2.5 Flash Lite through OpenRouter as of 6 November 2026: Google AI Studio. Each provider's price, context limit, quantization and measured uptime are in the providers table above.
Which benchmarks has Gemini 2.5 Flash Lite been evaluated on?
Gemini 2.5 Flash Lite has published results on 1 public board tracked by ModelCap as of 6 November 2026: BFCL V4 36.9 (#39 of 83). Each board page ranks every tracked model on that benchmark. The ModelCap Index scores the results its methodology admits, with published uncertainty, and shows reference boards without scoring them.
When was Gemini 2.5 Flash Lite released?
