Sweden’s Government Offices will block ChatGPT and Claude on staff computers. It directs civil servants to Microsoft Copilot as the only approved tool. The ban starts on Monday. Copilot passed a security review that ChatGPT and Claude did not. Some staff can still access the blocked tools through an internal platform. The Government Offices has not said how many people this covers. The move follows similar bans by Sweden’s Tax Agency and National Board of Institutional Care. The Enforcement Authority is preparing its own decision. An audit found widespread risky AI use at the Transport Administration.
