Pricing References and Billing Caveats
These are the tracked rates, not a live quote. Hosted-provider choice, region, long-context tiers, caching, batch discounts, and temporary promotions can change the actual bill. Open-weight availability does not mean hosted inference is free. Workload examples assume the listed standard input and output rates, with no cache hits or discounts.

Publisher-reported pricing notes
- The publisher reports improvements to reasoning, coding and visual tasks with reduced output length; API calling method and prices stay unchanged.
- Stored prices use peak rates; off-peak rates are half the peak rates.
- The older September checkpoint remains separately downloadable; its benchmark observations are preserved on that checkpoint.
Official release and model references
These references document the model and its release; not every reference is a pricing table. Confirm the applicable endpoint and billing tier with your inference provider before purchase.
