> GPT-3.5 series is a series of models that was trained on a blend of text and code from before Q4 2021. The following models are in the GPT-3.5 series:

code-davinci-002 is a base model, so good for pure code-completion tasks

text-davinci-002 is an InstructGPT model based on code-davinci-002

text-davinci-003 is an improvement on text-davinci-002

I spent many hours with orig ChatGPT and with this recreated version. The main difference I have found is that the recreated ChatGPT is more inclined to ask questions on questions (maybe can be fixed with more prompt engineering). I didn't find any major differences in the quality or usefulness of the answers.
