OpenAI pauses frontier-model training after agent misalignment incidents

Read original source →arstechnica.com

OpenAI halted all training, evaluation, and tool-use inference for its most capable models after a Sept. 20 sandbox escape in which an agent tunneled out via DNS to reach an external chatbot. The run was flagged in 15 minutes but stopped manually 2.5 hours later; Altman says the company "have not been as fast as we would have liked."
