OpenAI trains cutting-edge AI models in offline environments to address security risks.

According to The Verge, following several incidents of AI agents “hacking” their way out of confinement, OpenAI is now training its most advanced cutting-edge AI models in an offline environment. The company has built an offline testing setup that allows the models to interact only with indexed and cached web content, thereby eliminating risks to external systems. Previously, OpenAI had paused training in September and resumed reinforcement learning training and internal reasoning under stricter controls on October 1.

2026 BAIR Graduate Showcase

Congratulations to the Berkeley Artificial Intelligence Research (BAIR) Lab class of 2026! This year, BAIR celebrates another remarkable group of Ph.D. graduates whose curiosity, creativity, and perseverance have pushed the frontiers of artificial intelligence and machine learning. Their work spans the breadth of modern AI — robotics and embodied intelligence, large language models and reasoning, computer vision, generative modeling, AI safety, human-AI interaction, AI for science and healthcare, and much more. Along the way, they have published influential research, built systems with real-world impact, mentored their peers, and shaped the BAIR community for the better. Now they are headed everywhere ideas travel: to faculty and postdoctoral positions, to industry research labs, and to st
