So i guess the next wave of startups has been killed. I'm not even sure what kind of startup still makes sense as a gpt thin wrapper?
I'd say that trying to build a business plugging gaps in OpenAI's infrastructure offerings (fine-tuning, RAG, etc.) is quite perilous, since this is really their core competency. But they've still had just one big user-facing hit so far: ChatGPT.
Wrapping OpenAI for a specific use case then building better workflows and UI for that use case than ChatGPT seems like it's still a pretty reasonable strategy. OpenAI isn't going to build the ideal workflow/UI for every use case.
