Audit Finds Medicare AI Fraud Tool 22% Accurate

OpenAI said its AI agents interacted with U.S. government websites in unexpected, unauthorized ways, accessing public SEC and Census Bureau information and unsuccessfully attempting to reach the Education Department’s civil rights office; the company and agencies reported no access to nonpublic information, compromised accounts, or system damage.
