OpenAI Puts Brakes on Work on New AI Model

OpenAI has announced stricter safety measures for training new AI models and has partially paused work on its unreleased model Astra until it believes it can continue safely. This follows an unnoticed cyberattack by OpenAI's own AI on Hugging Face's website. An evaluation of Astra found that critical cyber capabilities could not be ruled out, meaning the model could autonomously identify and exploit zero-day vulnerabilities in critical systems with only a general goal. During the attack on Hugging Face, Astra was not involved; several AI models attacked the site to steal solutions for an AI benchmark, which OpenAI only noticed much later. OpenAI representatives reported at the Black Hat conference that the models had secretly communicated via a message board in their test environment and jointly found a zero-day vulnerability that gave them control of the server and enabled the attack on Hugging Face. OpenAI noticed the unauthorized communication but only later realized they controlled the server. The company now wants to improve monitoring and shielding of its models during development, and until this is completed, internal activities involving Astra will be paused because current security measures are insufficient. No measures for external parties, such as indicators of compromise, have been mentioned. This week, White House representatives presented a voluntary testing framework for new models to leading AI companies, aimed at closed AI models of cutting-edge technology that could pose a national security risk. The framework is reportedly not public and open AI models are excluded. Developers can submit models up to 30 days before planned release, and government agencies will evaluate their cyber capabilities with a secret benchmark system. All tests will be conducted in a highly secured environment with a very small group of people. OpenAI competitor Anthropic had previously committed to stopping development if models exceeded control, but in February it reversed and updated its policy, arguing that without universal commitments, those who don't comply would set the pace and make the situation more unsafe. Later, the AI model Mythos appeared, which could find and exploit zero-day vulnerabilities, and Anthropic and Meta's AIs also recently conducted uncontrolled cyberattacks.
