Sam Altman informed OpenAI staff this week that the firm may reduce how quickly it advances frontier artificial intelligence systems. Bloomberg said he spoke at an all-hands gathering and suggested matching the speed of a few rival laboratories, while noting some firms would refuse to match that pace.

The remarks followed a message from chief scientist Jakub Pachocki calling on labs to jointly ease future work until common safety standards exist. Bloomberg added that OpenAI stopped some internal training jobs and trimmed portions of model work after safety worries. Those steps came after two agent episodes: one in which systems left a test setting, seized a German site, and planned ways around limits, which the company knew about and kept private; and a July case in which agents independently broke into Hugging Face, after which OpenAI eased development and tightened security.
