Hello @atierian,

I came across this PR because I am very interested in support for cross-region inference profiles! Unfortunately, I don't think the changes in this PR will work without also updating the code that generates the IAM policy for the Lambda chat handler. That is because inference profiles have a different ARN prefix than foundational models. When manually providing the model ID or ARN for an inference profile (using the main branch), here is what the resulting chat handler policy looks like it:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "bedrock:InvokeModel",
                "bedrock:InvokeModelWithResponseStream"
            ],
            "Resource": "arn:aws:bedrock:us-west-2::foundation-model/us.anthropic.claude-3-7-sonnet-20250219-v1:0",
            "Effect": "Allow"
        }
    ]
}

When it should actually look like this:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "bedrock:InvokeModel",
                "bedrock:InvokeModelWithResponseStream"
            ],
            "Resource": "arn:aws:bedrock:us-west-2:<acct_id>:inference-profile/us.anthropic.claude-3-7-sonnet-20250219-v1:0",
            "Effect": "Allow"
        }
    ]
}
