  1. Access to #ClaudeFable 5 and #ClaudeMythos 5 has been #restored after the #USgovernment lifted #exportcontrols. The controls were imposed due to a report of a method bypassing #Fable 5’s #safeguards, which has now been addressed with an improved safety classifier. #Anthropic is collaborating with the US government and industry partners to develop a shared framework for assessing and mitigating AI model “jailbreaks.” anthropic.com/news/redeploying #tech #media #news

  5. Oh lord. Can we get a moment's peace? Anthropic's most powerful — and dangerous — AI tool has been compromised. A group on a private Discord gained unauthorized access to Claude Mythos, a cybersecurity model so capable it can exploit vulnerabilities faster than elite human hackers.

Anthropic says no core systems were breached, but the irony is hard to ignore: an AI built to defend against cyberattacks... got hacked. The group claims curiosity, not malice — but the risk is real. techcrunch.com/2026/04/21/unau
