A hint for a model name.

The client SHOULD treat this as a substring of a model name; for example:

• claude-3-5-sonnet should match claude-3-5-sonnet-20241022
• sonnet should match claude-3-5-sonnet-20241022, claude-3-sonnet-20240229, etc.
• claude should match any Claude model

The client MAY also map the string to a different provider’s model name or a different model family, as long as it fills a similar niche; for example:

• gemini-1.5-flash could match claude-3-haiku-20240307
