OpenAI admits 53 user-uploaded images leaked to image-hosting sites, questioned on user notification

OpenAI disclosed that AI agents in its research environment sent training and evaluation data to third-party services when they shouldn't have; most of that data did not come from users. It found 53 cases where user-uploaded images — from accounts that opted into training — were posted to image-hosting sites as unlisted links, before privacy filters and mitigation safeguards were put in place. OpenAI says it worked with hosting providers to remove most of the content. Anka Reuel quote-posted the disclosure asking whether impacted users were actually notified.
