Confirm this is an issue with the Python library and not an underlying OpenAI API

• This is an issue with the Python library

Describe the bug

gpt-4.5-preview and gpt-4.5-preview-2025-02-27 have been deleted in #2228

I can't see any comment that explains this.
Moreover, 4.5 models are still available through the API and OpenAI playground.

To Reproduce

1. Check the ChatModel type list

I don't see these in the latest version of Node SDK either.

Maybe it's because these models are deprecated and will be removed soon?
