- NSA is deploying Anthropic’s Mythos AI model despite a Pentagon blacklist, according to Axios.
- Pentagon moved in February to cut off Anthropic and required its vendors to stop using its products.
- Anthropic’s Mythos is reportedly being used widely within the Department of Defense, per a source.
- NSA is using a preview version of Mythos, as noted in multiple reports.
- UKAISI (UK security agency) also has access to Mythos, per a tweet.
Why it matters: The NSA’s deployment of Mythos despite the Pentagon’s blacklist shows that agency‑level AI adoption can proceed even when higher‑level risk assessments flag a vendor, highlighting a tension between security policy and operational needs within U.S. defense agencies and signals that security risk designations may not halt critical AI usage.
