OpenAI Updates Preparedness Framework v2 With Continuous Frontier AI Governance Model

OpenAI released an updated Preparedness Framework v2, last revised on April 15, 2025, outlining a comprehensive governance approach for managing risks across the entire lifecycle of frontier AI systems. The framework shifts away from one-time pre-release evaluations toward continuous monitoring, security controls, and formal oversight spanning training, deployment, and post-deployment operations. It introduces a risk categorization system with Tracked Categories — Biological and Chemical, Cybersecurity, and AI Self-improvement — alongside Research Categories for emerging risks, with High and Critical thresholds determining when safeguards must be in place before deployment. Security measures described include network segmentation, workload isolation, zero-trust access principles, and continuous incident-response capabilities, treating frontier AI safety as both an alignment and infrastructure challenge. The framework also mandates Capabilities Reports and Safeguards Reports to document system risks and controls, with oversight provided by a Safety Advisory Group tied to formal deployment decisions.
