The ResponseModel property returns the model name reported by
the provider for the most recent response. This value is taken directly
from the response metadata returned by the provider.
The model name returned by this property may differ from the value of
the ModelName property used when the request was sent. Some
providers may internally map model aliases to different model versions,
redirect requests to updated models, or return a more specific model
identifier than the one originally requested by the application.
Applications should treat this value as informational. The format and
naming conventions used for model identifiers are provider-specific and
may change over time. If the provider does not include a model name
in the response metadata, this property returns an empty string.
