Standard token rates
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $5.00 | 1,500 |
| Output | $30.00 | 3,000 |
Prompt caching: 90% off input tokens
Caching drops input cost from $5.00 to $0.50/MTok. For repeated system prompts, that saves $0.006750 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.
