What is RSI?

RSI (Recursive Self-Improvement) refers to the point at which AI becomes so good at training itself that it spawns a dramatic acceleration in AI capabilities. According to Anthropic, this threshold is seen in AI-risk circles as a point of no return.

What Anthropic says

The company said it is "very close" to this capability. The statement suggests RSI is not merely a theoretical concept but a development that could arrive in the near term.

Why it matters
