[r/LocalLLaMA] [Project] Karpathy autoresearch project— let AI agents run overnight LLM training experiments on a single GPU

Summary

Andrej Karpathy's "autoresearch" project introduces an AI agent that automates LLM training experiments. Operating on a single GPU overnight, the agent iteratively edits `train.py`, runs 5-minute training sessions, and evaluates `val_bpb` to improve models. This "AI researcher in a loop" concept allows for rapid, autonomous experimentation with minimal human intervention beyond the initial research prompt.
