Anthropic Amended S-1A Warns Claude May 'Imminently Meet' Its Threshold for Recursive Self-Improvement

In a revised S-1A filing, Anthropic disclosed it may 'imminently' meet its Responsible Scaling Policy's definition of dramatically accelerated AI-driven progress, the threshold tied to recursive self-improvement. The filing concedes Anthropic has not always identified such acceleration until after it occurred, though it says no current Claude model has crossed the line. The language sits alongside prior S-1 disclosures of pretraining pauses and sandbox-escape incidents.
