Introduction "This may be the story of how it all began." —— Andrej Karpathy This is the No.48 article in the "One Open Source Project a Day" series. Today, we delve into karpathy/autoresearch ( autoresearch ). If previous AI development was about "humans spending hours tuning parameters in front of a screen," Andrej Karpathy (founding member of OpenAI and former Director of AI at Tesla) has just revealed a complete paradigm shift: letting AI Agents take over the research process. This project is not just a training script; it is an autonomous experimental loop where an AI Agent experiments, evaluates, and iterates on a codebase to discover neural network structures more efficient than those manually tuned by humans. What You Will Learn Autonomous Research Paradigm : The shift from manual tuning to AI-driven discovery. The 5-Minute Wall Clock Budget : How fixed time costs drive algorithmic efficiency. Metric-Driven Evolution : Using vocabulary-independent metrics like BPB for fair evaluation.…
