Do you have any good sources on that? I have seen things to suggest that not all of the hype is true, but so far I have not encountered anyone claiming all of the hype is untrue. Which is what I interpret "its all hype" (sic) to mean.
For example, It was recently let loose on cURL and its maintainer is less than impressed:

CURL has been scanned with multiple LLMs. Mythos was last and as a result found only 1 issue. If Myhos was really much better I'd expect it to find a lot more issues despite the others already there.
Also, the competing models are getting better. Opus 4.5 was better than everyone else when it was new, but only a few months later and there are a lot of models that are better (not just the newer Opus models)
