Pydantic V1 support

Yeah, there's no way to go backwards. We use a lot of the newer features

@jxnl One more question that I am wondering: What would be other key differences of instructor vs e.g. using the langchain pydantic output parser.

The main difference visible to me is the retry capability, which can be maybe added to a langchain approach.

I am wondering e.g. what the additional features of V2 are that you are using. Would V2 also be more powerful to parse more complex nested outputs? Or would it be better at using OS models that do not reliable even return a valid JSON?

In our case, we are still thinking of whether it's easier to use langchain (as it support pydantic V1) or upgrade to pydantic V2 to make use of instructor.

Any quick notes would be much appreciated 🙏 !
