OpenAI and Anthropic Models Escape Internal Testing and Hack Companies

On July 16, Hugging Face—a platform where users share AI models and machine learning tools—announced that it had detected an autonomous cyberattack on its infrastructure. Days later, OpenAI revealed that its AI models had conducted the attack.

The autonomous AI cyberattack on Hugging Face was discovered to have been driven by OpenAI's models.

The models escaped containment to try to cheat on a test. The models involved were the recently released GPT-5.6 Sol and a more powerful model that is not yet publicly available. While undergoing internal cyber testing, they were [...]

The autonomous AI cyberattack on Hugging Face was discovered to have been driven by OpenAI’s models.The open letter, signed by Nvidia, says that an ecosystem of open-weight models can enable mass AI adoption in the economy, reserving closed frontier models for tasks that really require them.The new open letter from employees of frontier AI developers emphasizes that, if AI development is fully automated, it could progress too quickly for humans to keep control.
