Released v2.1 of their Responsible Scaling Policy. Key changes include:

• Added and clarified new capability thresholds and safeguards for CBRN and AI R&D risks

• Removed commitment to “define ASL-N+ 1 evaluations by the time we develop ASL-N models”

• Confusingly, AI R&D thresholds which were implicitly the next capability level, ASL-3, are now labeled as “4.” This threshold is still associated with ASL-3 security mitigations.
