**UK Gov’s Mythos AI Tests Help Separate Cybersecurity Threat from Hype**

The UK government’s AI Security Institute (AISI) has published an initial evaluation of Anthropic’s Mythos Preview model, adding independent public verification to previous reports. AISI found that while Mythos isn’t significantly different in individual cybersecurity tasks compared to other models, its ability to chain these into multi-step attacks could set it apart.

**Takeaways:**

– **Initial Evaluation:** The UK government’s AI institute has evaluated Anthropic’s Mythos Preview model.
– **Cybersecurity Focus:** The evaluation centers on the model’s capabilities in cybersecurity-related tasks and how they compare with other models.
– **Potential Differentiation:** While not notably different, Mythos could excel at chaining multiple attacks into a more sophisticated intrusion.
