Anthropic Releases Guardrailed Claude Fable 5 as Public Version of Mythos

Anthropic has released Claude Fable 5, a public version of its previously restricted Mythos AI, adding guardrails that block or reroute high-risk cybersecurity queries. In this Emerging Issue Briefing, IANS Faculty Jake Williams and Summer Fowler will break down what was released, where the guardrails may fall short, and what it means as AI accelerates vulnerability discovery across enterprise environments, along with clear takeaways for how CISOs should communicate the risk to executives.
