Anthropic's Mythos model identified vulnerabilities in classified U.S. government systems during a Project Glasswing testing exercise

no surprise that the whole NSA story was complete clickbait bullshit

@kimmonismus the more context that comes out, the crazier it sounds

@kimmonismus they could have just clarified this earlier

@kimmonismus Feels like we are just getting drips and drabs from every other source possible rather than Anthropic as to news on Fable 5

@Ananth7e yeah, true. sucks a bit

@RrichPRMR "its a good mode, sir"

@kimmonismus Again, I may not understand what's happening here but wasn't this exactly the point of project glasswing and the subsequent decision to create fable as a 'neutered' version of mythos to avoid precisely this predicament? I'm so confused why would this lead to a worldwide fable ban

While this may currently appear to be a minor concern, we should proactively consider the implications of myths six and seven, and explore potential future scenarios. A significant portion of the population remains unaware of the transformative changes ahead and the crucial role the open-source community will play in navigating them.

@kimmonismus This should have been said earlier and the unnecessary panic and mixed feelings about Mythos could have been avoided

@kimmonismus Thanks for the updates. I wonder why it so good at hacking. Is it part of an emergent property? Was it trained to do this type of thing? It's definitely not the thing we need it to do the best at this stage...hope it gets as good at novel science and medical breakthroughs.

@kimmonismus If this is true, how can they ever release frontier models to the public?

@kimmonismus We live in a banana republic

@scaling01 yep, didn't believe it as it was told once

@kimmonismus sounds like a skill issue, maybe they should develop classified systems that aren't so full of vulns; if their shit wasn't garbage in the first place then mythos would have a harder time exploiting it

@kimmonismus well that AP clarify was fast

vulnerabilities found vs exploited is the real line, and most people blur it on purpose

@kimmonismus The system’s defenses aren’t secure enough; blame the overly powerful model for breaching it

@kimmonismus found vs exploited. warner’s “broke into” line is doing a lot of work that AP’s own reporting doesn’t support

still insane that it took hours either way

@kimmonismus ok that's amazing but I want just Fable to be back so I can make better software, its gonna be much better in cybersecurity but what does it mean for us

@kimmonismus glasswing was the program right?
