How to use the 'name' parameter?

[skytect]

In the OpenAI API, you can provide a name parameter to a message.

In https://platform.openai.com/docs/api-reference/chat/create:

name
string

Optional
An optional name for the participant. Provides the model information to differentiate between participants of the same role.

I understand that the role can be configured using _.role("user"). What about name?

The name parameter is not yet supported, we do support metadata for content parts like cache_control for anthropics apis.
