1. OpenAI Details Safety and Alignment for Long-Horizon Models

OpenAI. OpenAI shared lessons from deploying long-horizon models that run autonomously over extended tasks, describing new categories of safety risk, observed failure modes, and the safeguards it has strengthened through iterative deployment. As models increasingly operate over sustained sessions rather than single responses, the alignment and oversight challenge shifts from individual answers to behavior over time, and OpenAI argues the safeguards have to move with it. It is a useful reference for teams putting autonomous agents into production and reasoning about how to monitor sustained behavior. Source
