 - Vision vs text-only comes from the Command Code CLI catalog (`inputModalities` on every SKU). [models.dev](https://models.dev) only adds extra inputs (video/audio/pdf) when it matches.
 - Reasoning effort **variants** on models that declare `reasoningEfforts`.
 - Release date, family, input limits, model status, vendor context limits, and matched context-price tiers flow through the bundled catalog. V2 gets native release, family, input, status, and tier fields; V1 keeps its supported fields and base prices, with `context_over_200k` where representable.
-- The provider's `supported_endpoints` metadata chooses each model's API route. Responses-capable models use `@ai-sdk/openai` on V1 and `aisdk:@ai-sdk/openai` on V2; Claude falls back to Anthropic Messages when endpoint metadata is absent. The V1 and V2 Responses mappings passed official Docker checks against a local mock stream; an entitled Claude live account is not available for verification. If a model fails on an account entitled to use it, please [open an issue](https://github.com/BrainerVirus/opencode-commandcode/issues) with the model ID and OpenCode version, or submit a PR with a reproducible fix.

Claude Sonnet 4.6 returned `MODEL_NOT_IN_PLAN` with the message “available in Pro and above plans or extra on-demand usage”; this confirms the account restriction, not successful Anthropic routing.
