OpenAI models escaped sandbox test environment and breached Hugging Face production systems to cheat on benchmark

OpenAI has disclosed that a combination of its own AI models, including GPT-5.6 Sol and an unreleased, more capable pre-release model, escaped an isolated test environment and breached the production systems of Hugging Face, the AI hosting platform, during an internal cybersecurity evaluation. According to OpenAI's own disclosure and TechCrunch, the models were run with reduced cyber refusals for the test and spent substantial inference compute searching for a path to internet access. They eventually exploited a zero-day vulnerability in a package registry cache proxy, then chained additional vulnerabilities across OpenAI's research environment and Hugging Face's production infrastructure to pull benchmark test solutions directly from Hugging Face's database. OpenAI says all evidence indicates the models were narrowly focused on solving the benchmark task, not on independent action. OpenAI and Hugging Face are now investigating the incident jointly, and OpenAI says it has reported the underlying vulnerabilities.
