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.
