ASL-3 security standards require multi-party authorization, hardware authentication, and temporary least-privilege access grants for model weights, with mandatory code review on production code affecting weights access, intended to reduce exfiltration risk.

This provision describes the access control architecture for model weights as a core ASL-3 security requirement, establishing procedural controls including multi-party authorization and hardware authentication tokens as prerequisites for any weights access.
Interpretive note: The document describes these as planned ASL-3 security controls with some already in place; the specific implementation status of each individual control is not fully specified.
Under these terms, access to Anthropic's model weights is governed by multi-party authorization requirements and temporary least-privilege access controls; these security mechanisms are described as planned ASL-3 safeguard implementations rather than currently deployed requirements in all cases.

"Implement multi-party authorization and mandatory code review on production code to remove persistent, high-privilege access to model weights. Grant temporary access and only via the smallest set of necessary permissions to reduce risk of weights exfiltration. Require hardware authentication device prompt, justification and employee approval to grant access.Excerpt from Anthropic's Responsible Scaling Policy
1) REGULATORY LANDSCAPE: Model weights security controls may engage with US export control regulations if model weights are treated as controlled technology, as well as with general data security obligations under frameworks such as ISO 27001, which the document explicitly references. The FTC's authority over reasonable data security practices is also relevant. 2) GOVERNANCE EXPOSURE: Medium. The security controls described are framed as planned ASL-3 implementations, and the document notes that many are already in place as enhancements to existing ASL-2 controls. The transition status of specific controls is not fully specified, limiting external assessment of current versus planned security posture. 3) JURISDICTION FLAGS: Export control exposure is heightened for model weights given US government interest in controlling frontier AI model access. Organizations in EU/EEA jurisdictions may also face obligations under the EU AI Act's requirements for model documentation and access management. 4) CONTRACT AND VENDOR IMPLICATIONS: Enterprise customers should assess whether Anthropic's model weights access controls are relevant to their own vendor security requirements and whether contractual terms address security standards applicable to model weights used in their products. 5) COMPLIANCE CONSIDERATIONS: Organizations with ISO 27001 or equivalent information security certifications should assess whether Anthropic's stated security controls align with their vendor security requirements. The document's reference to ISO 27001 alignment provides a framework basis for vendor security assessments.
