2026-09-18

Added

  • Priority service tier on /v1/chat/completions. Set "service_tier": "priority" on supported models. See Service Tiers.
  • Flex service tier on /v1/chat/completions. Set "service_tier": "flex" on supported models for a lower price when your workload can wait. See Service Tiers.

Changed

  • usage.estimated_cost is no longer included in responses from chat completions, embeddings, responses, and native inference. Where a response includes the _devup object, _devup.cost_dzd is the amount charged for the request.
  • usage.prompt_tokens_details.cache_write_tokens is no longer included. usage.prompt_tokens_details.cached_tokens is unchanged.
  • choices[].message.name is no longer included when its value is null.
