model %q is not available for provider %q; available models:

Error message

model %q is not available for provider %q; available models: %s

What it means

When a --model override is passed, the resolver validates it against the provider's model list (preset models plus entry models), when such a list exists. Bedrock/ambient-auth providers skip this gate because their model identifiers are account/region-scoped. This error means the requested model is not in the provider's known list.

	// A preset's Models list doubles as an allowlist for --model. For an

Solutions

1. Run `ocr config model` to see and pick from the provider's available models
2. Pass a model name exactly as listed in the error's "available models" list
3. Add the model to the provider entry's models list if your endpoint genuinely serves it
4. If the model is account/region-scoped (Bedrock), use a bedrock provider so the list gate does not apply

Example fix

// before
ocr review --model claude-opus-4-20250514
// error: model "claude-opus-4-20250514" is not available ...

// after
ocr review --model claude-sonnet-4-20250514  // a model from the available list

// Go: validate the --model override against the provider's list first

			return true

ep, ok, err := resolver.ResolveEndpointWithModelOverride(cfg, modelOverride)

}

When it happens

Trigger: Running `ocr review --model <name>` (or ResolveEndpointWithModelOverride) where the model name does not match any entry in the provider's Models list while the list is non-empty and the provider is not ambient-auth.

Common situations: Typos in the model name; using a model alias not present in the preset's compiled list; a newly released model added upstream after the list was frozen; picking an OpenAI model name for an Anthropic preset.
