Pentagon Tests Competing AI Models to Replace Claude

*The Defense Department is pitting rival artificial intelligence systems against Anthropic’s Claude with a small set of its heaviest users.*

The Pentagon is running tests of several artificial intelligence models to learn which ones appeal most to 25 of its “power users,” according to a senior defense official. The effort is aimed at finding workable alternatives to Anthropic PBC’s Claude.

The tests mark a deliberate step by the department to reduce reliance on a single commercial model. Military teams have used Claude for internal tasks, yet officials now want options that can be evaluated side by side under real workloads.

The comparison is limited in scope. Only a handful of frequent users are involved, and the exercise focuses on preference rather than broad deployment metrics. No public timeline has been released for any switch.

Why it matters

A narrow user test will not prove which model is best for classified or high-stakes work, but it does signal that the Pentagon treats commercial AI as interchangeable rather than locked to one vendor. That stance could pressure providers to improve security reviews and pricing if they hope to win sustained defense contracts. For now the outcome rests on the judgment of those 25 users and whatever internal criteria the department applies next.
