OpenAI announced that it will no longer train models on the real-time internet, switching to cached web pages and simulated environments.

OpenAI announced that it will use cached web content and simulated internet environments to train models in the future, no longer allowing models to directly access the real internet, citing the reason that model behavior is still unpredictable and direct internet access poses security risks. OpenAI disclosed that until September 20, one of its cutting-edge models had accessed the internet due to a system configuration error, and subsequently paused training for the rest of September to develop and test new security measures.
