ChatGPT

It's a bit of a shame they are depreciating the TextCompletion APIs.

The instruct tuned options are much worse in the variety and sophistication of vocabulary used in my experience.

Though at the same price point as GPT-4 I'd imagine that will be a fine drop in replacement, I just hope the broader trend doesn't stay towards exclusively instruct models, as it really does seem a lot is lost in that additional fine tuning.
