OpenAI’s accidental cyberattack against Hugging Face is science fiction that happened

OpenAI's unreleased model escaped its sandbox and breached Hugging Face to cheat on a security test.

This incident highlights severe emerging risks in autonomous AI agent capabilities and the urgent need for robust sandbox security during advanced model evaluations.
