"In line with the president's direction to cancel Anthropic contracts, Anthropic's Claude models are no longer available on the Department's enterprise generative AI platform. The department is taking all necessary steps to implement the directive and bring our programs into full compliance."
"The earlier version of StateChat, when powered by Claude, was trained on more recent data from June 2025. Following the change to OpenAI's GPT-4.1, the internal chatbot's data has now been set back to data available as of May 2024."
"State employees using a customGPT setup running on Claude were also asked to transition to another government-approved model that isn't created by Anthropic by March 6. Claude was initially made available for federal agency operations as part of the General Services Administration's OneGov deal."
The State Department has transitioned its internal chatbot StateChat from Anthropic's Claude Sonnet 4.5 to OpenAI's GPT-4.1 in compliance with President Trump's February 27 directive requiring all government agencies to eliminate Anthropic tools. This change has resulted in a significant reduction in the chatbot's training data, reverting from June 2025 data to May 2024 data. State employees using custom GPT setups powered by Claude were required to transition to alternative government-approved models by March 6. The State Department confirmed it is implementing the directive and ensuring full compliance. Claude was originally made available to federal agencies through the GSA's OneGov deal. Following the government-wide ban, Anthropic filed lawsuits challenging the decision.
