Anthropic warns AI on the brink of building itself: Explaining RSI and why it matters

In financial disclosures and technical publications, AI safety powerhouse Anthropic released warnings that it may soon cross a watershed threshold in artificial intelligence — Recursive Self-Improvement (RSI).

According to updated SEC filings and internal reports released by the maker of the Claude AI ecosystem, AI models are now generating more than 80% of Anthropic’s internal codebase and accelerating hardware and algorithmic research loops at speeds that human engineers cannot match. The milestone marks a critical inflection point in computer science.
