What Gemini 2.5 Flash-Lite costs on real work
Four workload shapes at 100,000 requests a month. The point of showing four is that the ranking between models changes depending on which one describes you.
| Workload | In | Out | Per request | Per month |
|---|---|---|---|---|
| ClassificationShort input, one-word answer. Input-dominated. | 500 | 50 | $0.000070 | $7.00 |
| Chat turnA system prompt plus a few turns of history. | 1,500 | 300 | $0.000270 | $27.00 |
| Document summaryA long document in, a paragraph out. | 20,000 | 800 | $0.002320 | $232.00 |
| Code generationOutput-heavy — where output pricing dominates. | 2,000 | 1,500 | $0.000800 | $80.00 |

Counting tokens for Gemini 2.5 Flash-Lite
Google does not publish a tokenizer that runs in a browser, so any pre-flight count for Gemini 2.5 Flash-Lite is an estimate rather than a measurement.
Gemini uses a SentencePiece tokenizer that has no browser build. Counted with o200k_base at parity; no published conversion factor exists, so treat this as an order-of-magnitude figure.
Treat it as accurate to within roughly ten to twenty percent. That is fine for budgeting and wrong for sizing a prompt right at a context window boundary — where precision matters, use Google’s own token counting endpoint from your backend. The methodology page sets out every scaling factor used here.

Frequently asked questions
- How much does Gemini 2.5 Flash-Lite cost?
- $0.1000 per million input tokens and $0.4000 per million output tokens. On a typical chat turn of 1,500 input and 300 output tokens that is $0.000270 per request, or $27.00 per month at 100,000 requests. Read from Google's own documentation on August 3, 2026.
- Can I count Gemini 2.5 Flash-Lite tokens exactly?
- No. Google does not publish a tokenizer that runs in a browser, so any pre-flight count for Gemini 2.5 Flash-Lite is an estimate. Gemini uses a SentencePiece tokenizer that has no browser build. Counted with o200k_base at parity; no published conversion factor exists, so treat this as an order-of-magnitude figure. Treat it as accurate to within roughly ten to twenty percent and never as the basis for sizing a prompt right at a context window boundary.
- Why is output more expensive than input on Gemini 2.5 Flash-Lite?
- Output costs 4.0 times input here. Input is processed in a single parallel pass, while output is generated one token at a time with a full pass over the model for each. That is why a model that answers concisely can be cheaper in production than one with a lower headline rate.
