Currently, quite comparable and obviously Instructor is more mature and feature rich. They're going the "patch the openAI client" approach which makes code written still use openAI SDK patterns which is pretty smart. Jason seems like he knows what he's doing.

We're trying to make it more of a language feature with the decorated functions. Plus exploring the hosted formatting model direction.

How do you feel this compares? Do you think there's any gaps in current tools worth working on?

Plus one on this question! Seems very similar.
