Researchers note that even before this next generation of models, existing AI offerings could be used for advanced vulnerability-hunting and exploit development with a refined harness.
Key facts
- The team need to prepare now for a world where these capabilities are broadly available in 6, 12, 24 months
- Late last week, Anthropic took its new Claude Fable 5 and Mythos 5 AI models offline following a United States government export-control directive barring “any foreign national” from using
- Anthropic itself noted this double-edged sword in its launch of Mythos 5 and Claude Fable 5
- Then, at the end of last week, the Trump administration moved to restrict both models because it believes that Fable 5’s guardrails can be disabled to allow full access to the Mythos 5 capabilities
Summary
Late last week, Anthropic took its new Claude Fable 5 and Mythos 5 AI models offline following a United States government export-control directive barring “any foreign national” from using the services. Since Mythos debuted in April, Anthropic has claimed—and warned—that the model has advanced capabilities for not only finding software vulnerabilities to help defenders patch them, but also figuring out ways to exploit them that could be used by bad actors. With this in mind, the company initially released a version called Mythos Preview to a select consortium as part of a working group known as Project Glasswing. Then, at the end of last week, the Trump administration moved to restrict both models because it believes that Fable 5’s guardrails can be disabled to allow full access to the Mythos 5 capabilities, allegedly making it a national security risk.
