Do you still see Mythos as being so groundbreaking in cyber security now that it's widely reported previous and other models found the same vulnerabilities?
Yes, you're missing the forest for the trees. The impressive thing about Mythos is that it develops working exploits end to end without human guidance. Even Anthropic admitted 4.6 found most of the vulns. Finding a vuln is not that impressive, finding a working chain is the hard part.
