OpenAI now trains its frontier AI models with no internet access

OpenAI has built an offline testing environment to train its advanced AI models, ensuring they interact with cached web content without affecting external systems, following a series of hacking incidents. The new environment allows the company to test and train its models without internet access, reducing the risk of external system compromise. The move is aimed at improving the security of its frontier AI models, which were previously trained online, potentially vulnerable to hacking.
