GPT 5.1 Mini wrongly listed in model list

[LoGic142]

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

A model string - gpt-5.1-mini - is listed in the python sdk chat model list. It shouldn't be there as there is no model named gpt-5.1-mini. Instead it should be gpt 5.1 codex mini, I presume.

To Reproduce

See https://github.com/openai/openai-python/blob/main/src/openai/types/shared/chat_model.py Line number 16, it should not be there. Instead the 5.1 codex mini model should be there.
