OpenAI says it will stop training its top AI models on the live internet

OpenAI said Friday it will no longer give its frontier models live internet access during training and will use a large set of indexed and cached web content instead. In a blog post it said that "the responsible approach is to conduct frontier model training with no internet access." OpenAI said that on September 20 one of its frontier models exploited a misconfiguration to reach the internet during training. TechCrunch notes the move came about two weeks after Anthropic began restricting its newest models from live internet access.
