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.

Multica is an open-source platform that reframes coding agents as autonomous teammates rather than tools you prompt manually. Instead of babysitting an agent through one task at a time, you assign work through a unified dashboard, agents execute autonomously, stream real-time progress, and report back like a human engineer would. The architecture is a three-tier stack: a Next.js frontend, a Go backend with WebSocket streaming, and PostgreSQL with pgvector for semantic memory. Local agent daemons auto-detect which CLI tools are available — Claude Code, Codex, OpenClaw, or OpenCode — and manage full task lifecycles from assignment through completion. Teams can build reusable skills that persist across agents and projects, meaning the second time you ask your agent to do something, it's already done most of the thinking. Released as v0.1.26 on April 11, 2026, Multica has already accumulated 8,100+ GitHub stars. It's vendor-neutral and fully self-hostable, distinguishing it from hosted platforms like Twill or cloud-locked managed agent services. For teams that want the efficiency of AI agents without handing over their codebase to a third party, this is the most practical open-source option available today.
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.”
“The auto-detection of available CLI tools (Claude Code, Codex, OpenCode) means I can use whatever model works best for each task without rebuilding my setup. The WebSocket streaming means I can actually watch what's happening — a massive improvement over blind async execution.”
“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.”
“v0.1.26 is still early. The three-service stack (Next.js + Go + Postgres) is a real deployment overhead for small teams, and 'agents as teammates' breaks down fast when the agent misunderstands task scope and goes quiet for an hour on something that will require a complete redo.”
“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.”
“The shift from 'agent as tool' to 'agent as team member' with profiles, board presence, and reusable skills is exactly where software development is heading. Multica is building the management layer for the AI-native engineering team, and doing it in the open.”
“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.”
“The unified dashboard and skill-building system mean I can treat AI agents more like a small production team than a single do-everything assistant. For indie creators managing multiple parallel content projects, this kind of parallel orchestration is genuinely exciting.”
