Auto-Arch Tournament is an autonomous research system where an AI agent iteratively proposes, implements, and validates microarchitectural improvements to a RISC-V CPU. Starting from a standard 5-stage pipeline, the loop runs hypotheses in parallel, each going through formal verification (53 symbolic checks), cycle-accurate simulation, multi-seed FPGA place-and-route, and CoreMark CRC validation. Only hypotheses that beat the current champion get merged; everything else gets discarded. Starting from 301 iterations/second, the system hit 577 iter/s (+92%) across 73 attempts in 9.8 hours — producing a design 26% faster and 40% smaller in LUTs than the baseline. The insight the author drives home is that the real innovation isn't the AI agent — it's the verifier. The orchestrator is hardcoded to prevent agents from manipulating their own evaluation gates, a simple but critical design constraint that turns a creative process into a trustworthy one. Without a rigorous verification harness, agent-driven optimization becomes a confidence trick. This is early but fascinating proof that AI-driven hardware design loops can produce commercially meaningful gains. The repo uses Claude Code or Codex as the coding agent, SystemVerilog for the RTL, and standard open-source EDA tooling (Yosys, nextpnr, Verilator). It's a compelling template for anyone building agentic optimization loops where correctness matters.

Extractor uses LLMs to reliably extract structured data from any webpage. Unlike traditional scrapers that break when HTML changes, Extractor understands the content semantically.
Reviewer scorecard
“The hardcoded orchestrator pattern is the real take-home here. Building AI loops that can't game their own eval is a solved problem when you just... don't give the agent write access to the evaluator. Obvious in hindsight, rarely implemented.”
“Traditional web scraping is brittle. LLM-powered extraction that understands content structure is the right approach. Works on messy pages where CSS selectors fail.”
“63 out of 73 proposals failed. That's an 86% failure rate and heavy use of API credits on a narrow RISC-V benchmark. Impressive for a demo but the economics don't work yet for serious chip design at scale.”
“The LLM cost per extraction makes it expensive at scale. But for high-value data extraction where accuracy matters more than cost, it is worth it.”
“AI-driven hardware design is going to collapse the chip design cycle from years to weeks. This is a primitive ancestor of the tools that will design the next generation of AI accelerators.”
“Web scraping becomes web understanding. As more AI agents need to read the web, tools like Extractor become essential infrastructure.”
“The blog post that comes with this repo is one of the best pieces of technical writing I've seen in months. The transparency about failure rates and the verifier insight make it genuinely educational.”
