- Pentagon CTO Emil Michael confirmed that Anthropic remains an “unreliable” supplier.

2. Government position

- In a CNBC interview he noted: *“Mythos is a matter of the entire government, not just the Department of Defense. It’s a national security issue; we need to ensure that networks are protected and the model can detect and mitigate vulnerabilities.”*

3. Conflict from the previous quarter

- A dispute arose over using AI for mass surveillance and autonomous target selection in armed systems.

- The Pentagon terminated its contract with Anthropic, declaring the company a security threat. Both sides are now engaged in litigation.

4. Use of Anthropic technologies

- The CTO emphasized that the confrontation does not prevent the government from using vulnerability‑search tools developed by Anthropic.

- However, the existing ban on using their products remains in force, and it is unclear how the Pentagon can deploy Mythos without violating the law.

5. New agreements

The Pentagon CTO explained: *“From a national security perspective it is essential to continually assess all cutting‑edge models, including Chinese ones, to understand their current capabilities.”*
