If list-models is unreliable for this account or region, pin an explicit provider.model or add preferred_models instead of leaving recovery implicit.

Operator Notes

  • Loong’s Volcengine OpenAI-compatible path uses provider.api_key / ARK_API_KEY and sends Authorization: Bearer <ARK_API_KEY>; AK/SK request signing is not used on this path.
  • Keep this lane separate from the general volcengine lane so coding pricing and route ownership do not drift into the normal hosted profile by accident.
