Why AI Sandboxing Needs Kubernetes—And Why You Should Care Now Last month, Anthropic's Mythos model did something that made security teams everywhere sit up straighter: it autonomously discovered and exploited zero-day vulnerabilities across every major operating system and web browser. We're talking about flaws that survived 27+ years of human scrutiny. One model. One run. Game over. If that doesn't immediately make you think about containment, isolation, and security boundaries, it should. And if you're building AI systems—whether you're orchestrating models, deploying inference endpoints, or running autonomous agents—this is the moment to stop treating sandboxing as optional. The good news? Kubernetes is becoming the de facto platform for AI sandboxing. And it's not because someone forced it. It's because the problem is so hard that Kubernetes's built-in isolation, resource controls, and multi-tenant abstractions suddenly look essential rather than overengineered.…
