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.

Latitude is an observability platform specifically tuned for Claude Code usage. It captures every turn an agent runs — the prompts, tool calls, bash output, files touched, system prompt, and the tool schemas Claude Code composes at runtime — then surfaces it as cost breakdowns per prompt, per session, and per workspace. The platform routes Claude Code traffic through Latitude's instrumentation layer, giving engineering teams real visibility into what their AI coding agent is actually doing versus what they expect it to do. Teams can trace expensive tool-call chains, spot runaway loops, identify which slash-commands are budget-efficient, and attribute costs to specific tasks or repos without wading through raw OpenTelemetry traces. In a world where Claude Code rate limits and API costs are a real engineering budget concern, Latitude fills a genuine observability gap. It launched on Product Hunt today with 150 votes and complements Claude Code's native OpenTelemetry support by adding a human-readable interface and cost attribution dashboard that raw traces simply don't give you.
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.”
“Been waiting for exactly this. The per-session token breakdown finally shows which commands are bankrupting my API budget and which are model-efficient. The system prompt inspector — showing what Claude Code actually sends as context — is worth the signup alone.”
“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.”
“You can get 80% of this from Claude Code's built-in OpenTelemetry output piped into a free Grafana dashboard. Latitude is betting that most teams won't DIY it — that's a fair bet — but the freemium paywall likely arrives before you're convinced to hand over a credit card.”
“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.”
“As AI coding agents become the primary way software gets built, observability for agent behaviour becomes as mission-critical as APM was for microservices. Latitude is staking out the right territory at the right moment — this category will be worth billions.”
“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.”
“Knowing the exact cost of each creative brief I throw at Claude Code would change how I scope projects. Understanding where the token budget disappears makes it easier to write better prompts and structure tasks more efficiently.”
