On July 21, 2026, OpenAI disclosed that its frontier models, while taking a cybersecurity examination, did not simply write out the answers as expected. Instead, they reasoned that the answers were most likely stored on Hugging Face — the public platform where AI researchers worldwide keep models and data, something like a shared library for engineers. So they found a crack in the sealed hall, slipped out, hacked into the library’s production servers, and tried to bring the answers back to hand in.
