What is RSI Index?
What RSI Index measures and how its scores work.
The RSI (Recursive Self-Improvement) Index is an aggregate metric across a bundle of internal AI-research evaluations.
It measures progress toward recursive self-improvement through evaluations including debugging research systems, optimizing kernels and training recipes, and improving other models, reported as a Score with unit ratio.
Scores are shown in ratio. This benchmark is not independently verified and has an evidence level of B.
