How I Let an AI Agent Run 100 ML Experiments Overnight on a $500 GPU Last week I let an AI agent run 100 machine learning experiments overnight on my RTX 3070. I woke up to a 25% model improvement. Here's exactly how it works. The Setup The agent is built on Karpathy's autoresearch concept, powered by Claude Sonnet. It runs in a loop: Propose — The agent analyzes current model performance and proposes a specific code change Implement — It writes the actual Python code to modify the neural networ
