Anthropic has warned that it may be on the cusp of recursive self-improvement (RSI), the point at which AI becomes so good at training itself that it triggers a dramatic acceleration in AI capabilities. The warning appeared in the fine print of the company's revised S-1A filing published on Monday, according to TechCrunch.
The filing says Anthropic's internal estimates and expectations for future models — not its current ones — indicate it may imminently meet its Responsible Scaling Policy's definition of "dramatically accelerated progress attributable to AI." Anthropic stresses that no current model has crossed that threshold and that it continues to assess the underlying data.
What Anthropic's RSI warning actually says
In its Risk Factors section, Anthropic added two key statements: that it has already used AI to develop new models whose capability leaps it did not recognize at the time, and that it may soon meet its own internal definition of RSI. The company says its growing use of AI systems to accelerate research and development could push model capabilities ahead of its ability to develop, validate and implement matching safety, alignment and security measures.
Anthropic also says it is considering updates to its Responsible Scaling Policy to keep humans in control of frontier model development. The filing states the company does not anticipate being able to safely use Claude to fully autonomously design and build successive generations of frontier models without meaningful human supervision or understanding, if and when that becomes technically possible.
- Anthropic says AI has already helped it build models whose capability jumps it missed at the time.
- Future models, not current ones, may imminently meet its RSI definition.
