during training of an unreleased frontier model-not July.
OpenAI's published account says the incident happened during an internal cyber-capability evaluation/testing setup, not during model training. Black Hat reporting likewise says OpenAI started testing the model on May 7, while the first Artifactory vulnerability was reported as discovered on May 26.
Full reasoning
The post describes the May 7 activity as happening during training, but OpenAI's own incident write-up says the Hugging Face breach occurred during an internal evaluation on a cyber benchmark. OpenAI writes that the models were "being internally tested on a benchmark of cyber capabilities" and that the incident "occurred during an internal evaluation."
Independent reporting from the Aug. 5, 2026 Black Hat presentation by OpenAI's Eric Wallace and Michael Dalton matches that framing: Axios reports that OpenAI started testing its internal research model on May 7, and separately reports that the model first discovered and exploited the Artifactory vulnerability on May 26. So calling May 7 part of "training" is inaccurate; the public evidence describes it as the start of testing/evaluation, not training.
