Hi @stellasia, thanks for getting back. Awaiting review!

Very nice work, thank you for taking the time to contribute! I left a few comments, the use of options to set the model temperature is the most important.

[kalrasamridhi7]

Thanks for the review, @stellasia! Sorry for getting back late. I have addressed all your comments.

Hi @kalrasamridhi7 ,
Thanks a lot for that! CI is failing due to some file formating but once this is fixed we'll be able to merge this PR 🎉

[kalrasamridhi7]

Previous tests were failing due to Ruff formatter checks. Fixed and changes pushed.
