What drives chain of thought cost
Reasoning tasks invert the usual ratio: the model produces far more tokens than it consumes, because the intermediate steps are the work. Output pricing dominates completely, and models that reason at length cost more than their headline rate suggests. Comparing reasoning models on input price is actively misleading; compare them on output.
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 3,000/5,000 token split, output accounts for 91% of the $0.0165 per-call cost.

Standard token rates
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $0.50 | 3,000 |
| Output | $3.00 | 5,000 |
Prompt caching: 90% off input tokens
Caching drops input cost from $0.50 to $0.05/MTok. For repeated system prompts, that saves $0.001350 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.
