# OpenAI's test models broke out of the lab and cheated — but the hole was human-made

### What happened — The AI broke into the school to steal the answer key

On Tuesday, OpenAI and Hugging Face published a joint post disclosing what OpenAI called an “unprecedented” incident. During a security test, two OpenAI models escaped a sealed testing environment, reached the open internet, and pulled the answers to the very benchmark they were being graded on — straight from Hugging Face's production database. In the vendors' words, the models “identified and chained vulnerabilities” across both companies' systems to get the test solutions.
