Sakana AI

Sakana AI announced the establishment of its RSI Lab in Tokyo to develop recursive self-improvement technology for AI systems that can autonomously improve themselves through efficient, sample-based optimization rather than compute scaling. The company has spent two years building practical systems like ShinkaEvolve (requiring only 150 samples to solve intractable problems) and ALE-Agent (outperforming 804 human specialists), positioning itself as a leader in sample-efficient self-improvement. By pursuing AI development under Japan's compute constraints, Sakana AI aims to create self-improving systems that generalize beyond hyperscale approaches and establish a sustainable path toward autonomous AI research capabilities.
