Developer API Rates

Direct token rate

No public direct API token price

The verified record does not store a fixed direct token rate.

Per-token API pricing is intentionally omitted from this first import because a current first-party token rate was not directly verifiable in this pass; subscription pricing is not interchangeable with API token pricing.

Pricing & Availability Notes

  • Z.ai's launch material describes 1M-context evaluation setups, but the canonical API context field is intentionally left empty until a direct API specification is verified.
  • The launch announcement scheduled public model weights after additional safety hardening; open-weight status is therefore not asserted in this import.
  • Per-token API pricing is intentionally omitted from this first import because a current first-party token rate was not directly verifiable in this pass; subscription pricing is not interchangeable with API token pricing.
  • No fixed direct API token price is stored in the current verified record
