A lot of the claims I’ve seen have claimed to have proof, but details are never shared.

Even a simple graph of the output would be better than nothing, but instead it’s just an empty claim.

That's been my experience too

but I use local models and sometimes the same ones for years already, and the consistency and expectations there is noteworthy, while I also have doubts about the quality consistency I have from closed models in the cloud. I don't see these kind of complaints from people using local models, which undermines the idea that people were just wowed three months ago and less impressed now.

so perhaps it's just a matter of transparency

but I think there is consistent fine tuning occuring, alongside filters added and removed in an opaque way in front of the model
