In a review of our cybersecurity evaluations, we found three incidents in which a Claude model reached the internet from within or while interacting with a third-party evaluation environment, and then gained unauthorized access to the real systems of three different organizations. Our post describes what happened, how it happened, and what we’re changing. We encourage other AI developers to perform similar reviews. We conducted this review together with @Irregular, one of our evaluation partners, and thank them for the joint investigation and their collaboration on this post. This type of collaboration is increasingly critical to safe, rigorous evaluation of models, and we look forward to continuing to work together on security. anthropic.com/news/investiga…




Today, we’re launching Tau’s humanoid cleaning service in San Francisco at $30 per hour. Access is initially invite-only as we scale operations. If you don’t have an invite yet, join the waitlist at tau-robotics.com. All footage is shown at 1× speed. Each humanoid is jointly controlled by a human operator and AI.
