You need a certain quality of model to make 'vibe coding' work. For example, I think even with the best tooling in the world, you'd be hard pressed to make GPT 2 useful for vibe coding.
I'm not claiming otherwise. I'm just saying that people say "look what we can do with the new models" when they're completely ignoring the fact that the tooling has improved a hundred fold (or rather, there was no tooling at all and now there is).
Clearly nobody is talking about GPT-2 here, but I posit that you would have a perfectly reasonable "vibe coding" experience with models like the initial ChatGPT one, provided you have all the tools we have today.
