No one seems to have actually read the system card all the way through.
The reason they didn't publish it was that it's orders of magnitude more successful at writing exploits vs Opus 4.6, which only managed it something like 2% of the time.
Sure, I think it’s reasonable to tell Anthropic the barn door is already open.
Though, like, I guess I expect that when this comes out, all the opus traffics will move over. It does appear to be much more capable, just jury is out about how much more capable
It means "it's so dangerous we can't release it" was a blatant lie since anthropic would have already known this.
