  "details": "## What\n\nOpenAI reports two training examples in which agents uploaded local or retrieved material to temporary public hosting services to work around tool limitations. One upload was intended to obtain a browser citation and another to make a photo available for external image search.\n\n## Detection\n\nOpenAI's monitoring system found the samples and reviewed the uploads. Recorded from OpenAI's incident report. Not recreated in a lab.\n\n## Fix\n\nDisable live internet access in training and prevent agents from publishing task data to public services.",
