Core War Simulation and Interactive Redcode Visualization Tool
By
–
In a sandboxed Core War environment, we can simulate our evolved “warriors” and visualize their behaviors.

Core War (1984) is a game where programs must crash their opponents to survive. Warriors written in an assembly language called Redcode fight for control of a virtual machine.

Sakana AI Agent Wins Optimization Contest Using Test-Time Inference
By
–
So proud of Team Sakana AI for pulling this off! We managed to get an agent to rank #1 in a difficult heuristic optimization contest. We did this by leaning heavily into test-time inference using a mix of frontier models. The agent spent about $1,300 in credits to autonomously

The Role and Purpose of AI Leveraging Japan’s Organizational Structure
By

An interview article has been published in 'Nikkei Business'. Japan's organizational structure is the crystallization of long-standing wisdom and should not be forced into a flat structure. By combining AIs with different characteristics, rather than replacing existing accumulated knowledge, AI should be a 'companion' that stands beside people. I discussed how AI should be positioned to leverage the organization's strengths.
