Scaling Karpathy’s AutoResearch Using Nebius Token Factory

Introduction We ran about 250 prompt optimization experiments overnight using a small AI agent loop. The idea was simple: let an AI system propose an experiment, run it, evaluate the result, and then try again with a better idea. Instead of manually testing prompts one by one, the system keeps improving its own attempts over multiple iterations. This idea comes from Andrej Karpathy’s AutoResearch , where an AI agent can automate the typical machine learning research cycle...
