Claude has been available on AWS Bedrock for a long time too.

The new "Claude Platform" announcement was about an Anthropic operated version on AWS (as opposed to self-operated on Bedrock). See the differences here: https://platform.claude.com/docs/en/build-with-claude/claude...

Claude has been available like that for quite a while.

One of the reasons for the OpenAI divorce from MS was so they could become available on AWS where they see significant demand, and being available only on Azure was holding them back.
