Season 1 Episode 24: Mythos - AI That Finds Vulnerabilities and Raises Alarms

Send us Fan MailWelcome  to AI Lens, the show where we break down the biggest stories in artificial intelligence — and more importantly, what they mean for you, your business, your identity, and your future. Anthropic, the company behind Claude, has developed an advanced AI model called Claude Mythos. This model has a remarkable ability: it can autonomously discover software vulnerabilities—bugs and security flaws—in complex codebases. And it's scarily good at it. But here's the problem: on April 21st, 2026, an unauthorized group gained access to Mythos. And that's raising serious questions about AI security, dual-use technology, and the risks of advanced AI systems falling into the wrong hands. This is a story about the cutting edge of AI capability, the security challenges that come with it, and the difficult questions we need to ask about how we develop and deploy powerful AI systems. WHAT IS CLAUDE MYTHOS? Let's start with the basics. Claude Mythos is Anthropic's most advanced AI model. It's not available to the general public. It's invitation-only, available only to vetted partners and organizations that Anthropic trusts. The reason for this restriction is Mythos's remarkable capability: it can autonomously discover software vulnerabilities. In other words, it can find bugs and security flaws in computer code without being explicitly told where to look or what to look for. This is a significant advancement over previous AI systems. Earlier versions of Claude, like Claude Opus 4.6, could find vulnerabilities, but they required step-by-step prompting from humans. Mythos can do it autonomously, without human guidance. Support the show
