Sakana AI's Recursive Self-Improvement (RSI) Lab
Sakana AI just open-sourced recursive self-improvement. That's autonomous model training without human annotation.

Why it matters
Sakana AI is pushing the frontier of model training methodology with recursive self-improvement (RSI), a capability that could reshape how companies iterate on models without costly human labeling cycles. This directly challenges the current training paradigm and has implications for model velocity across the industry.
