Bedrock: Cross Region Inference capability

[medha-hegde]

Describe the feature

The new cross-region inference profiles allow us to use the same Bedrock model in other regions by switching out the foundation model ARN with this inference profile ARN:

However, in the Amazon Bedrock Construct Library only allows for Foundation Models or Provisioned Models.

Can we incorprate this new cross-region inference profiles feature ASAP?

Use Case

I am invoking the Bedrock API via Step Functions tasks with this code currently:

claude_model_id = bedrock.FoundationModelIdentifier.ANTHROPIC_CLAUDE_V2_1
invoke_model = tasks.BedrockInvokeModel(
        scope,
        id + " (Invoke Model)",
        model=bedrock.FoundationModel.from_foundation_model_id(
            scope,
            "Model",
            claude_model_id,
        ),...

ideally I'd like to simply switch out the claude_model_id for the inference profile ARN.

Proposed Solution

Allow for custom ARNs instead of enforcing the bedrock.FoundationModelIdentifier class for the model IDs.

Makes sense. We can consider to create a new static method for that. We welcome any PRs from the community.
