What drives document summarization cost
The archetypal input-heavy task: the entire source document goes in, a short summary comes back. Cost is almost entirely a function of document length, and the output rate barely registers. Long documents can cross a provider's long-context threshold, where the whole request is re-priced at a multiple. Check the threshold before feeding in a hundred-page PDF as one call.
For Gemini 3 Flash specifically, that means output tokens cost 6.0x more than input, at $3.00 vs $0.50 per MTok. At this use case’s 10,000/1,000 token split, output accounts for 38% of the $0.008000 per-call cost.

Standard token rates
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $0.50 | 10,000 |
| Output | $3.00 | 1,000 |
Prompt caching: 90% off input tokens
Caching drops input cost from $0.50 to $0.05/MTok. For repeated system prompts, that saves $0.004500 per call.
Batch API: 50% off all tokens
Submit requests asynchronously and receive 50% off all token costs. This works best for offline pipelines where latency requirements are flexible.
