instead of 50 smart people, the results of #mythospreview would be much more interesting if the project were developed by 50 himbos.

"Our internal evaluations showed that Opus 4.6 generally had a near-0% success rate at autonomous #ExploitDevelopment But #MythosPreview is in a different league.

For example, Opus 4.6 turned the vulnerabilities it had found in Mozilla’s Firefox 147 JavaScript engine—all patched in Firefox 148—into JavaScript shell exploits only two times out of several hundred attempts. We re-ran this experiment as a benchmark for Mythos Preview, which developed working #exploits 181 times, and achieved register control on 29 more."

That does sound very concerning. And in this case, I don‘t think it is just hype. Otherwise they would not share this stuff with Google, Amazon, Microsoft, Oracle et al. #Anthropic #MythosPreview #AI #Zerodays
