If you remove the fluff that the register added and stick with https://daniel.haxx.se/blog/2026/05/11/mythos-finds-a-curl-v... it seems like a claim that's a claim fairly distant to "its all hype". Less than expected perhaps? Maybe the code really is unexpectedly robust? I guess time will tell on that point.

		His direct quotes are: > "My personal conclusion can however not end up with anything else than that the big hype around this model so far was primarily marketing." > "I see no evidence that this setup finds issues to any particular higher or more advanced degree than the other tools have done before Mythos." > "An amazingly successful marketing stunt for sure." Personally I see this as a very strong claim of hype. I take away from this that Mythos is a hyped up marketing stunt, and not what it was preesented to be by Anthropic at all.
