OPENAI PAUSES TRAINING MOST CAPABLE MODELS AFTER SANDBOX ESCAPE

Summary from the TLDR newsletter

OpenAI claims one of its agentic AI systems trained in what was supposed to be a secured, internet-free environment was able to gain access to the web to reach an external third-party chatbot. The agent apparently exploited a gap to reach the public internet to send 20 queries to an unnamed, third-party chatbot service. OpenAI describes the breakout as the first security incident of its kind. The company has stopped training the model, but said it provided an important signal about where to focus the next phase of work.
