Anthropic Responsible Scaling Policy v3.0
RSP v3.0 went into effect February 24, 2026, replacing the 2023 policy. Two-tier mitigation: what Anthropic will do unilaterally vs what is framed as an industry-wide recommendation (including RAND SL-4 security standards). Adds Frontier Safety Roadmaps and Risk Reports as standing documents rather than one-off deliverables. Drops the 2023 pause commitment. Introduces the AI R&D-4 threshold: once crossed, Anthropic must publish an affirmative case identifying misalignment risks and mitigations. Claude Opus 4.6 does not cross it. Anthropic states in the v3.0 announcement that "confidently ruling this out is becoming difficult." SaferAI rated the 2023 RSP at 2.2; they downgraded v3.0 to 1.9, putting Anthropic in the "weak" RSP category alongside OpenAI and DeepMind. Qualitative thresholds replaced the 2023 quantitative commitments; removing the pause clause is the sharpest regression.
