Summary
Anthropic presents its Frontier Compliance Framework (FCF) developed in response to California's Transparency in Frontier AI Act (SB 53), which requires frontier AI developers to establish safety and compliance procedures. The framework details Anthropic's methodology for assessing and mitigating catastrophic risks from advanced AI systems, including evaluation protocols and safety measures. This represents a concrete example of how a leading AI lab operationalizes regulatory compliance around AI safety.
Key Points
- •Anthropic developed the FCF specifically to comply with California's SB 53, which mandates frontier AI developers to have documented safety and risk mitigation procedures.
- •The framework addresses potential catastrophic risks from frontier AI systems, including assessments of dangerous capabilities like CBRN threat uplift and cyberweapons.
- •FCF builds on Anthropic's existing Responsible Scaling Policy (RSP), extending internal safety commitments into a regulatory compliance context.
- •The framework includes structured evaluation protocols and thresholds that determine when additional safety measures or deployment restrictions are required.
- •This document serves as a public accountability artifact, making Anthropic's safety commitments and procedures transparent to regulators and the public.
Review
Anthropic's document presents a comprehensive approach to AI safety regulation, specifically addressing the requirements of California's SB 53. The Frontier Compliance Framework (FCF) represents a proactive stance on managing potential catastrophic risks from advanced AI systems, covering areas such as cyber offense, chemical, biological, radiological, and nuclear threats, as well as risks of AI sabotage and loss of control.
The framework goes beyond mere compliance, proposing a broader vision for AI safety regulation at the federal level. Anthropic advocates for a flexible, adaptive approach to AI transparency that balances safety concerns with innovation, emphasizing public visibility into safety practices, protection of whistleblowers, and targeted application to the most advanced AI developers. This approach demonstrates a sophisticated understanding of the evolving AI landscape, recognizing the need for regulatory frameworks that can adapt to rapid technological changes while maintaining robust safety standards.

Sharing our compliance framework for California's Transparency in Frontier AI Act \ Anthropic Policy Sharing our compliance framework for California's Transparency in Frontier AI Act
Dec 19, 2025 On January 1, California's Transparency in Frontier AI Act ( SB 53 ) will go into effect. It establishes the nation’s first frontier AI safety and transparency requirements for catastrophic risks.
While we have long advocated for a federal framework, Anthropic endorsed SB 53 because we believe frontier AI developers like ourselves should be transparent about how they assess and manage these risks. Importantly, the law balances the need for strong safety practices, incident reporting, and whistleblower protections—while preserving flexibility in how developers implement their safety measures, and exempting smaller companies from unnecessary regulatory burdens.
One of the law’s key requirements is that frontier AI developers publish a framework describing how they assess and manage catastrophic risks. Our Frontier Compliance Framework (FCF) is now available to the public, here . Below, we discuss what’s included within it, and highlight what we think should come next for frontier AI transparency.
What’s in our Frontier Compliance Framework
Our FCF describes how we assess and mitigate cyber offense, chemical, biological, radiological, and nuclear threats, as well as the risks of AI sabotage and loss of control, for our frontier models. The framework also lays out our tiered system for evaluating model capabilities against these risk categories and explains our approach to mitigations. It also covers how we protect model weights and respond to safety incidents.
Much of what's in the FCF reflects an evolution of practices we've followed for years. Since 2023, our Responsible Scaling Policy (RSP) has outlined our approach to managing extreme risks from advanced AI systems and informed our decisions about AI development and deployment. We also release detailed system cards when we launch new models, which describe capabilities, safety evaluations, and risk assessments. Other labs have voluntarily adopted similar approaches. Under the new law going into effect on January 1, those types of transparency practices are mandatory for those building the most powerful AI systems in California.
Moving forward, the FCF will serve as our compliance framework for SB 53 and other regulatory requirements. The RSP will remain our voluntary safety policy, reflecting what we believe best practices should be as the AI landscape evolves, even when that goes beyond or otherwise differs from current regulatory requirements.
The need for a federal standard
The implementation of SB 53 is an important moment. By formalizing achievable transparency practices that responsible labs already voluntarily follow, the law ensures these commitments can't be abandoned quietly later once models get more capable, or as comp
