- NSA is using Anthropic's Mythos Preview despite the model being designated a supply‑chain risk and blacklisted by the U.S. government.
- Department of Defense is also using Mythos widely, even after the agency moved in February to cut off Anthropic and required its vendors to follow suit.
- White House chief of staff Susie Wiles met with Anthropic CEO Dario Amodei and investor Scott Bessent, calling the meeting “productive and constructive” and seeking a compromise on Mythos access.
- MI5 in the United Kingdom has been called in to protect Britain from a “breakthrough AI threat” linked to Anthropic’s Mythos model.
- Anthropic has delayed a broader release of Mythos, citing recent outages and the need to ensure reliable service before scaling to customers.
- U.S. officials are debating whether Mythos is too valuable for the federal government to refuse, as the model continues to be used despite the blacklist.
Why it matters: The U.S. agencies gain a powerful AI tool for defense and intelligence, but its use sidesteps a blacklist, raising supply‑chain security worries; Anthropic’s delayed rollout and outages pressure the firm to prove reliability, while the White House must decide if the model’s value justifies overlooking its risk.
