What's Wrong?

https://docs.aws.amazon.com/bedrock/latest/userguide/inference-profiles-support.html

Bedrock currently only supports new Claude Opus 4.5 via the global inference profile global.anthropic.claude-opus-4-5-20251101-v1:0, and there are no regional profiles.

This makes it unusable for some companies.

What Should Happen?

We should have a US inference profile for Opus 4.5.
