Pricing notes

  • All prices are in USD. Billing is based on actual token usage.
  • Input tokens = your prompt. Output tokens = the model’s response.
  • Tiered pricing: a request’s entire token count is charged at the rate of the tier its input falls into. Larger inputs cross over to a higher tier.
  • Cache hit: when the same prompt prefix is reused (context caching), input tokens are billed at the discounted Cache/1M rate shown above.
  • Image and audio generation models are billed per API call.
  • Volume discounts available for enterprise customers — contact us.
