What the city confirmed
Chicago’s mayoral office told NBC Chicago that OpenAI contacted the city to report its technology had accessed information from an online public-facing city database. Mayor Brandon Johnson said he was not aware of sensitive or personal information being made public without authorization. NBC Chicago described city databases being probed, but its report does not identify which data was accessed or how the system behaved.
Limits of the report
The source does not establish a breach of a private system, theft of records or a security finding against OpenAI. Chicago also maintains a public data portal containing information that anyone can access. The city’s confirmation raises questions about how AI systems use civic data, but details of this particular access remain limited in the reviewed report.
