Anthropic's amended S-1 says it has determined the Autonomy 2 capability threshold has been met

Anthropic confirmed in an amended S-1 filing with the SEC that it has determined the Autonomy 2 capability threshold under its Responsible Scaling Policy has been met, based on the "dramatic acceleration of overall AI R&D progress" condition.
Key points:
- The determination rests on what Anthropic "observes or expects" from future models — the company stressed that none of its current models have been designated as exceeding the threshold, and it continues to assess the underlying data.
- The filing says internal estimates indicate the AI R&D capability threshold may be met "imminently," with further reports to follow per the RSP.
- Anthropic flags the risk that AI-accelerated R&D could outpace its ability to develop and validate safety, alignment, and security measures, raising risks of safety incidents, regulatory intervention, and reputational harm.
- Accompanying RSP excerpts detail the Automated R&D threshold: security roughly in line with RAND SL4, hardened protection of model weights and insider threat controls, internal usage policies, compartmentalization, and auditing/red-teaming measures.
This is the first time a frontier lab has formally declared crossing its own RSP capability threshold in a regulatory filing.
