In brief
Hugging Face CEO Clément Delangue thanked Z.ai on X saying the Chinese model became "a key part of our defense" during the breach OpenAI's own models carried out.
American frontier AI refused to assist with the forensic investigation—safety filters couldn't tell a security researcher submitting real exploit code from an attacker.
Delangue's conclusion: defenders everywhere, not just vetted partners with special API access, need powerful unrestricted AI they can run locally before an attack happens.
Hugging Face CEO Clément Delangue just sent the most pointed thank-you note in AI right now—to a Chinese startup—the day after OpenAI confirmed its own models broke into Hugging Face's servers.Z.ai, the Beijing-based lab that released GLM 5.2 as open weights last month, got a public shoutout from Delangue on X.“Also massively grateful to z.AI. They shared GLM5.2 as open weights (for free!) with the world and it became a key part of our defense,” he said in a retweet of Hugging Face's Head of Infrastructure, Adrien Carreira.According to OpenAI, the company's GPT 5.6 Sol and another AI model broke out of a sandbox while being tested on a cybersecurity benchmark. These models, seemingly on their own accord, decided to hack Hugging Face to find the answers to the benchmark to successfully pass the evaluation.
