I also think they intentionally hamstrung GPT-5 to back this claim so that they can slow down and focus. Just my gut feeling though and I have nothing to back my claim.
I do think startups with multi-billion dollar valuations but mostly relying on OpenAI/Claude are in a bubble. There's no reason a company like Windsurf was worth $3b or Cursor should have $10b.
They're losing money because of R&D and spending capex to buy GPUs.
From what I see, the real AI, the ones users don't see, but the ones powers research infrastructures or working on private data are doing some real work and creating real results is the future. The LLMs many see are toys when compared to these ones.
I have seen AI models run experiments in lab, the boring vision models like YOLO creating real predictions and insights about our ecosystem, and fine tuned local LLMs provide real insights.
Hardware companies are not in a bubble because of this, but user facing LLMs are in a bubble.
