OpenAI’s moat is not _that_ big in the grand scheme of things.

You can train GPT2 in a couple weeks on a dozen GPUs. Sure, it’s a lot worse than GPT4, but not insanely behind and the community is fast.

Same for RLHF. It is for sure fine engineering, but not unreachable for a motivated and competent bunch.
