Anthropic is saying other models were good at detecting vulnerabilities, where Mythos excelled was in creating functional exploits for them.

This article only talks about detecting vulnerabilities, so it's unclear if it's a true Mythos equivalent.

It seems "Mythos is really good at finding vulnerabilities" has been what people took away from the Project Glassing announcement, which makes sense. Unfortunately for Anthropic, most seem to have forgotten the best argument Anthropic had for holding Mythos back from the general public, "it's crazy good at crafting exploits". Then, without that context, the tinfoil hats came out.
