State Dept Dumps Claude for GPT-4.1 After Trump Order

The State Department has ditched Anthropic's Claude Sonnet 4.5 and migrated its internal chatbot to OpenAI's GPT-4.1. The switch came after Trump issued a directive to cancel government contracts with Anthropic.

An internal document obtained by Nextgov/FCW confirms the move, showing the agency's chatbot now runs entirely on OpenAI's model.

The shift marks a significant shakeup in how federal agencies source their AI tools. Anthropic — once a key player in government AI deployments — finds itself on the outside looking in, at least within State Department operations.

GPT-4.1 now powers the department's internal AI workflows. The transition highlights how executive directives can rapidly reshape the government AI vendor landscape, forcing agencies to swap foundational models on short notice.

No word yet on whether other federal agencies are making similar switches.
