AFAIK a lot of these ideas are not new (the JSON thing was done with OS models before) and OpenAI is possibly the hottest startup with the most funding this decade (maybe even past two decades?), so I think this is actually all within expectations.

It depends on how you define startup but I don't think they will surpass Uber, ByteDance, or SpaceX until this next rumored funding round.
I'm excluding companies that have raised funding post IPO since that's an obvious cutoff for startups. The other cuttof being break even, in which case Uber has raised well over $20 billion.
They're exceptional at executing and delivering, you don't get that just through having more funding.
