Nadella: assume all AI models are compromised, build containment

Microsoft CEO Satya Nadella posted on X arguing AI can no longer be treated as a set of nested black boxes. He calls for contained, observable systems that leave tamper-proof, human-readable evidence. His recommendations include timely incident disclosure, independent audits and verifiable data.

Why it matters: A major platform vendor publicly adopting a 'zero trust for models' stance follows a run of agent containment failures, including Anthropic cutting internal evals off from the internet. It signals that containment and audit trails may become enterprise procurement requirements, shaping how agents get deployed.
