| Anthropic | Responsible Scaling Policy | 3.4 | Jul 8, 2026 | Version 3.0 (February 24, 2026) rewrote the policy around a public Frontier Safety Roadmap and periodic Risk Reports, specified mitigations only for the next capability level, and dropped the earlier implied pause commitment. Later versions let the Long-Term Benefit Trust request external review of Risk Reports and revised the automated R&D threshold. |
| OpenAI | Preparedness Framework | 2 | Apr 15, 2025 | Tracks biological and chemical, cybersecurity and SI self-improvement capabilities against High and Critical thresholds, with a Safety Advisory Group advising leadership. OpenAI announced a full rewrite on August 18, 2026 after judging a model may have reached the Critical cyber threshold; no replacement version had been located as of this update. |
| OpenAI | Frontier Governance Framework | May 2026 | May 28, 2026 | Maps OpenAI's safety and security practices to California's frontier transparency law and the EU General-Purpose AI Code of Practice, covering cyber offense, CBRN, harmful manipulation and loss of control. It sits alongside the Preparedness Framework and does not replace it. |
| Google DeepMind | Frontier Safety Framework | 3.1 | Apr 17, 2026 | Sets Critical Capability Levels for CBRN, cyber, harmful manipulation and ML R&D, and adds Tracked Capability Levels, including one for stealth and situational awareness tied to misalignment. Reaching a Critical Capability Level requires a safety case and governance approval before external or high-risk internal deployment. |
| Meta | Superintelligence Scaling Framework | 2.1 | Oct 2, 2026 | The October 2026 revision of the framework previously titled the Frontier AI Framework sets Critical, High and Moderate risk levels across cybersecurity, chemical and biological, and loss of control outcomes. High risk models deploy only with mitigations that bring risk to moderate, and development past Critical continues only when catastrophic risks are judged acceptable. |
| xAI | Frontier Artificial Intelligence Framework | June 30, 2026 | Jun 30, 2026 | Commits xAI to at least annual systemic risk assessments covering CBRN, offensive cyber, loss of control and harmful manipulation, with release only when risks are judged acceptable. It also sets security controls for model weights and an incident response process that can include shutting systems down. |
| Microsoft | Frontier Governance Framework | February 2026 | n/a | Screens Microsoft's most advanced models for CBRN, offensive cyber, advanced autonomy, loss of control and harmful manipulation capabilities, rescreening at least every six months. Risks must be brought to low or medium before deployment, or development and deployment pause. |
| Amazon | Frontier Model Safety Framework | September 2026 | Sep 17, 2026 | Sets Critical Capability Thresholds for CBRN weapons proliferation, offensive cyber operations and loss of control, and commits Amazon not to deploy a model that meets a threshold until safeguards bring risk to acceptable levels. This is the reviewed update of the first 2025 version. |
