Some azure models use max_completion_tokens and some of them use max_tokens

I'm trying to use o4 mini from azure open ai and I get following error:

RuntimeError: API request failed: 500 - {"detail":"Error executing transformation: Error code: 400 - {'error': {'message': \"Unsupported parameter: 'max_tokens' is not supported with this model. Use 'max_completion_tokens' instead.\", 'type': 'invalid_request_error', 'param': 'max_tokens', 'code': 'unsupported_parameter'}}"}

I found out that the parameter was changed:

https://community.openai.com/t/why-was-max-tokens-changed-to-max-completion-tokens/938077/3

Would you be able to make changes in the open notebook?

Yes, will work on it

Thanks! Open notebook is awsome project!

Closing this since o4 is deprecated and Gpt 5.2 is already supported.
