Pliny claims a universal jailbreak, then withholds it

Pliny says he found a jailbreak that broke every flagship model he tested, including Opus 5 on its launch day, according to a July 24 post on X. He calls the technique nearly impossible to patch. If that holds, every lab shipping a flagship this year is carrying an exposure it can't fully close.

Nobody outside his own account has reproduced the exploit. Pliny has a documented history of posting working jailbreaks on launch day, but this time he says he isn't publishing. He's citing the political climate and a responsible-disclosure window as the reason.

The July 24 post has pulled 558,948 views and 9,326 likes. That's attention, not verification.

The capability claim is unverified and might stay that way outside his own telling. What's new here is behavioral, not technical: the account that built its name posting jailbreaks the same day it found them is now the one asking for patience.
