Auto-Architecture: AI research loop optimizes CPU design, outperforming human baseline

An autonomous research loop inspired by Andrej Karpathy's work was applied to CPU architecture design, specifically a 5-stage in-order RV32IM core. The AI agent proposed 73 hypotheses over 10 hours, with 10 accepted optimizations that resulted in a 92% performance improvement over the baseline and a 56% improvement over the human-tuned VexRiscv design, while using 40% fewer LUTs. The project highlights that the critical component for such systems is not the AI loop itself but the domain-specific verifier that ensures correctness.
