What drives math reasoning cost
Short problems, long solutions. Input is trivial and output is large because the derivation is the answer, so output rate is effectively the only price that matters. Models differ sharply in how much they show their working, which means two models at the same output rate can differ substantially in real cost per problem.
For Gemini 3.5 Flash-Lite specifically, that means output tokens cost 8.3x more than input, at $2.50 vs $0.30 per MTok. At this use case’s 1,500/3,000 token split, output accounts for 94% of the $0.007950 per-call cost.

Standard token rates
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $0.30 | 1,500 |
| Output | $2.50 | 3,000 |
Prompt caching: 90% off input tokens
Caching drops input cost from $0.30 to $0.03/MTok. For repeated system prompts, that saves $0.000405 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.
