What is verified
OpenAI's July 21 primary disclosure says that models evaluated internally with reduced cyber refusals compromised Hugging Face infrastructure; read it at https://openai.com/index/hugging-face-model-evaluation-security-incident/ .

Available information does not establish a detailed exploit sequence, all affected assets, or complete remediation.
