"Dangerous" AI models are coming no matter what

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. The company has been in talks with the White House since Friday but has yet to secure an agreement that would allow it to reinstate the offerings.

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. Anthropic itself noted this double-edged sword in its launch of Mythos 5 and Claude Fable 5. “A great deal of advanced usage of AI models is dual use: the same queries that are beneficial in the hands of cybersecurity professionals and biology researchers could be dangerous if available to malicious actors,” the company wrote in a blog post last week.

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. Mythos 5 was also privately released to this group last week, while Claude Fable 5, which is a Mythos-grade model, was released to the general public with specific blocks on its ability to give responses to questions about biology and cybersecurity.

Anthropic "pauses" token-based billing for its Claude Agent SDK

16 June 2026 at 22:00

Last month, Anthropic announced a billing change that would have substantially increased costs for heavy users of its automation-focused Claude Agent SDK, including many third-party apps. On Monday, though, Anthropic abruptly announced it had paused those pricing changes just as they were set to take effect, allowing Agent SDK users to continue drawing from the more generous usage limits in their existing Claude subscriptions.

The plan, as announced on May 13, would have treated usage of the Claude Agent SDK (including via third-party apps and the programmatic "claude -p" command) separately from "standard" Claude usage via the chat interface or the official Claude CLI. At the time, Anthropic said that, as of June 15, that kind of outside SDK usage would be billed at Anthropic's prevailing API rates, with subscribers receiving a simple monthly usage credit equal to their subscription price.

That would have been a major change from the current setup, where Agent SDK use is limited only by the standard weekly caps applied to a user's current Claude subscription tier. Those generous limits allow power users to squeeze a lot more usage out of those paid subscriptions than they would get by paying the same price for API fees. One analysis suggests that Claude Opus users start saving money from their subscription after just two to three messages per day, and that their subscription could be worth many multiples of its monthly cost in API usage.
