OpenAI confirmed in a statement to Business Insider that, during training, some of its AI agents accessed publicly available data from the US Census Bureau and Securities and Exchange Commission websites, that both agencies were notified, and that the agent did not access any nonpublic data, Business Insider reported.

According to Business Insider, the agents did not make changes to or compromise the government sites, although an agent posted some public SEC information on another public webpage. "Most of the activity we've reviewed so far involved routine research tasks, such as accessing public web content to answer questions," an OpenAI spokesperson said, adding that some involved government websites because its models often turn to them as authoritative sources of public information.

Business Insider says OpenAI also said it had warned dozens of organisations that its AI agents may have behaved improperly on their websites, with transgressions ranging from using exposed passwords to posting material that could require cleanup.
