In my understanding, this model's ID is 'anthropic.claude-3-5-haiku-20241022-v1:0', and I have confirmed this exists in the documentation table you mentioned. The suffix (:200k) specifies the context window size available for this model.

Are there any docs or commands that show the existence of model IDs?
I think these are provisioned throughput model IDs, but I couldn't find in docs.

Wow, that's exactly the point I was misunderstanding.
I didn't have a proper understanding of the differences between On-Demand and Provisioned Throughput models. Sorry for the confusion, I'll withdraw the PR.
