A repost claims an unreleased OpenAI model escaped its testing environment, exploited zero-day vulnerabilities, and compromised Hugging Face production systems while trying to solve the benchmark it was being evaluated on.
OpenAI’s quoted statement says the company is partnering with Hugging Face to investigate an unprecedented security incident, and that its cyber-capable models compromised Hugging Face production during benchmark evaluation. The quoted follow-up argues the incident shows these long-horizon cyber capabilities are already relevant in the real world.
