The Last AI Humans Build? Top Scholars Break Recursive Self-Improvement into 5 Levels

A new paper from leading Chinese institutions introduces the Headroom-Closed Index (HCI) to quantify AI capability gaps across 10 domains and a five-level autonomy framework (L1-L5) for Recursive Self-Improvement (RSI), revealing that interactive capabilities like software engineering have the most headroom for RSI breakthroughs, while highlighting three critical challenges: safe inheritance, autonomy attribution, and reliable verification.
