Model IDs and Capabilities
Anthropic model IDs pass through unchanged and do not need to be registered. The package does not ship a model inventory; the Anthropic API remains the authority on whether a particular model accepts a requested feature.
Capabilities describe what the Anthropic adapter can serialize. The Anthropic API returns a normalized SDK exception if the selected model or requested feature is rejected.
