POST /v2/models/{provider}/{model}. Comfy is the default provider. For models with alternate coverage, model_provider selects another provider without changing the model ID or request body. See model_provider, strict_mode and fallback_provider in the API reference.
Provider coverage
strict_mode=false (the default) translates the native request and response for the selected provider. Fields that cannot be translated are listed in the X-Comfy-Router-Dropped-Params response header.
