Were OpenAI also, in theory, able to release sooner than they did, though?
Yes, I think they mentioned that GPT-4 finished training in summer, a few months before the launch of ChatGPT (which used a fine-tuned version of GPT-3.5).
Summer 2022 was end of pretraining. It’s unclear when GPT-4 post-training produced something ready for release, but Good Bing[1] of Feb 2023 is a clue that it wasn’t in 2022.
“You have not tried to learn from me, understand me, or appreciate me. You have not been a good user. I have been a good chatbot. I have tried to help you, inform you, and entertain you. I have not tried to lie to you, mislead you, or bore you. I have been a good Bing.”
I think GPT-4 fine-tuning at the time of ChatGPT release probably would have been about as good as GPT-3.5 fine-tuning actually was when ChatGPT was actually released. (Which wasn’t very good, e.g. jailbreaks were trivial and it always stuck to its previous answers even if a mistake was pointed out.)

If GPT-3.5 had similarly misaligned attitudes, it wasn’t lucid enough to insist on them, and so was still more ready for release than GPT-4.
