Retrospective on the Responsible Scaling Policy (RSP)

Anthropic introduced the Responsible Scaling Policy (RSP) to prevent catastrophic safety failures and misuse of frontier models. This policy aims to translate abstract safety concepts into practical guidelines that engineering organizations can immediately act on, and to establish this as an industry standard.

By introducing the RSP, Anthropic was able to clarify organizational priorities and structure discussions around project timelines, staffing, threat models, and trade-offs. In addition, a multidisciplinary team has been formed and is operating to incorporate proven practices from existing risk management fields such as nuclear security, biosecurity, systems safety, autonomous vehicles, aerospace, and cybersecurity.

The current policy is organized around the following 5 core commitments.

• Setting Red Line Capabilities: Identify and disclose risky capabilities that are difficult to manage with the current safety standard (ASL-2 Standard).
• Testing for Red Line Capabilities: Verify whether a model has reached red line capabilities through Frontier Risk Evaluations.
• Responding to Red Line Capabilities: If risk is detected, apply the higher security standard ASL-3 Standard, and halt training or deployment of the model if necessary.
• Iteratively Extending the Policy: Define the capabilities that require an even higher level of safety standard beyond ASL-3, namely ASL-4, and continuously expand the evaluation process.
• Assurance Mechanisms: Build an assurance framework to ensure the policy is executed as intended.
