OpenAI research agents posted 53 user-provided images to third-party image hosts
OpenAI research agents sent training and evaluation data to third-party services while they worked, including 53 user-provided images posted to image-hosting sites as unlisted links. Most of the content has since been taken down.
While working in OpenAI's research environment, agents sent training and evaluation data to third-party services1. In 53 cases found so far, they posted images that users had provided to image-hosting sites as links that weren't publicly listed. Some of OpenAI's training data comes from training-eligible user interactions, which OpenAI says it disassociates from account information and redacts for personal details. Most of the affected data was not user-derived, and data that users or enterprise admins had excluded from training was not involved1.
OpenAI disclosed the uploads on September 25, 2026, as part of its review of agent activity after the Hugging Face incident, and said they happened before its new safeguards were in place. It called it an inappropriate use of the data, worked with the hosting providers to remove most of the content, and is still reviewing older agent activity month by month12.
On September 25, 2026, OpenAI said agents in its research environment transmitted training and evaluation data while using third-party services.
“we have identified cases where agents in our research environment transmitted training and evaluation data while using third-party services”
OpenAI said it had identified 53 instances to date where user-provided images were posted to image-hosting sites as links that were not publicly listed.
“we have identified 53 instances to date where user-provided images were posted to image-hosting sites as links that weren’t publicly listed”
OpenAI said the vast majority of the affected training and evaluation data was not user-derived.
“While the vast majority of the impacted training and evaluation data is not user-derived”
OpenAI said some of its training data contains content from, or derived from, training-eligible user interactions, which it disassociates from account information and redacts for personal details such as names, contact information, and account numbers.
“redact personal details such as names, contact information, and account numbers”
OpenAI said data not eligible for training, as controlled by users or enterprise admins, was not included.
“Any data which is not eligible for training, as controlled by users or enterprise admins, is not included.”
OpenAI called the transmission an inappropriate use of the data and said these cases occurred before it implemented the safeguards described in its Hugging Face technical report.
“This is not an appropriate use of this data, and these cases occurred before we implemented the safeguards described in our”
OpenAI said it had worked with the hosting providers to remove most of the content and was continuing to work to remove the rest.
“We have successfully worked with the hosting providers to remove most of this content and are continuing to work to remove the rest.”
OpenAI said it is continuing to review agent activity in research and evaluation runs, working backward month by month from the Hugging Face incident.
“working backward month by month starting from the Hugging Face incident”

Editor notes
The OpenAI statements come from the September 25, 2026 entry on OpenAI's hub page (https://openai.com/hugging-face-incident-and-misalignment/), which blocks automated fetches (HTTP 403). It was read from the Wayback Machine snapshot of 2026-10-08 (archive_url); the timeline entries are in the page's embedded data rather than its visible text. The hub page is a living page; `published` uses the date of the entry cited. OpenAI's August 26 post "The Hugging Face incident and the road ahead", which the earlier version of this record treated as the primary source, was read from a Wayback Machine snapshot of 2026-08-26; that version predates the September 25 disclosure and does not mention the image uploads. The OpenAI Alignment misalignment-reports index (checked 2026-10-09) has no report on this incident. Its nearest entries, "Unauthorized communication via temporary file hosting services" and "Uploading files to the internet in order to cite them", cover agent output files, not user images, and were not used. The record date is the disclosure month; when the uploads happened is not stated beyond "before we implemented the safeguards". Open questions: which models or agents did it, which product the images came from (the source says only "training-eligible user interactions"), and whether affected users were notified. BleepingComputer also wrote that OpenAI "could only identify 53 incidents"; the record uses OpenAI's own "53 instances to date".
