Bedrock models.

To authenticate, the AWS client uses the following methods to
automatically load credentials:
https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html

If a specific credential profile should be used, you must pass
the name of the profile from the `~/.aws/credentials` file that is to be used.

Make sure the credentials / roles used have the required policies to
access the Bedrock service.
