Cheapest viable option: Gemini 3.6 Flash at $0.0307/call (69% less, 76/100 quality).
The most output-heavy use case tracked here. A brief of a few hundred tokens produces an article of several thousand, so output pricing is essentially the entire cost and input rate is noise. Generating section by section rather than whole-article gives you more control over both quality and spend, at the cost of more calls.
For Gemini 3.1 Pro specifically, that means output tokens cost 6.0x more than input, at $12.00 vs $2.00 per MTok. At this use case’s 1,000/8,000 token split, output accounts for 98% of the $0.0980 per-call cost.
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $2.00 | 1,000 |
| Output | $12.00 | 8,000 |
Caching drops input cost from $2.00 to $0.20/MTok. For repeated system prompts, that saves $0.001800 per call.
Submit requests asynchronously and receive 50% off all token costs. This works best for offline pipelines where latency requirements are flexible.
