Volcengine Coding

Dedicated coding lanes that keep coding quota, pricing, or route ownership separate from the general assistant lane. This page covers the built-in volcengine_coding provider kind directly.

loong runtime models list
loong ask --message "Say hello and name the active provider."

If runtime models list 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.

Continue to Providers And Models when you still need the broader chooser page.
Continue to Provider Guides for the full built-in provider matrix.
Continue to Provider Recipes for representative rollout recipes.
Continue to Configuration Patterns for the shared provider-profile shape.
