Ask HN: Does it feel like AI progress is slowing down, or being hidden?

In my head recent changes in AI came in 3 periods 1. GPT-3 -> ChatGPT 2. ChatGPT -> GPT-4 3. GPT-4 -> now 1, discussion about AI was big in the tech field but ignored in the mainstream. During 2, it was all the buzz everywhere and new developments were emerging at a rapid pace (stable diffusion, LLama, etc.) Now however during period 3 it feels like there's a big dampener on all the buzz, either because things are slowing down or that progress isn't being shared. Currently, while there is still a huge buzz in the field, it feels quieter than period 2. I imagine it's because companies are hiding their progress more to ensure their competitive advantage. My question is, has the open hype over AI during period 2 moved "underground" to private discussions between tech workers and researchers? Is all the accelerating change happening behind NDA's?
