Yeah, I can see this being useful for one-off queries, but don't they want to offer some sort of final training ("last-mile" I called it in another comment. I can't remember what the proper term is.) to companies to customize the model so it already has all the context they need baked in to every query?
They used to offer exactly this for fine tuning models. Never offered it after ChatGPT, I think the difficulty comes with fine tuning RLHF models, not obvious how to correctly do this.
