Karpathy's Autonomous Research Agent Runs 276 Experiments Unsupervised, Delivers 11% Model Improvement

Andrej Karpathy left an AI research agent running for 48 hours without intervention. It executed 276 experiments and reduced his nanochat model's training time by 11% — a concrete demonstration of autonomous AI research at work.

Andrej Karpathy shared results from what may be the most compelling public demonstration of autonomous AI research to date. Three days ago, he set his "autoresearch" agent to work tuning nanochat, a small language model project, and walked away. When he returned, the agent had run 276 experiments entirely unsupervised, as @karpathy documented.
