Is ChatGPT 3.5 turbo model not available anymore?

Hi,

I am building a new project, based on 100% working code from a previous project that I uploaded 2 weeks ago. For some reason, ChatGPT 3.5 turbo model is not available anymore or has changed name or I cannot find it and everything defaults to gpt2 - which in turn makes my code non-functional.

Was there a change in the models list that HF supports?

Thank you.
