Could you build this?
No Automating CPU architecture search and hardware design requires deep computer architecture research, HDL generation (Verilog/Chisel), and cycle-accurate hardware simulation.
What it would actually take: Requires an orchestration framework linking LLMs with cycle-accurate simulators (like gem5) and RTL toolchains (Yosys, Verilator) to synthesize, benchmark, and iteratively optimize processor instruction sets and microarchitectures. Building a meaningful auto-architecting loop requires specialized domain expertise in computer architecture, digital logic verification, and hardware synthesis pipelines.
Discussion
20 comments analyzed.
Competitors mentioned: Karpathy's loop (autoresearch), genetic algorithms, stochastic gradient descent, evolutionary algorithms
Concerns raised: AI lacks insight into optimizations and doesn't explain why changes work, Junior engineers won't learn underlying principles using AI optimization, Performance gains appear to be PnR noise rather than real improvements, Benchmark overfitting - CPU only as good as its benchmark, AI doesn't flag margin closeness or architectural limitations
Feature requests: Apply optimization loop to nextpnr for Xilinx, Altera, Lattice FPGAs, Hardware specifications for replication (Digikey, Mouser compatible), Optimize against real applications instead of just benchmarks, Better naming convention (K-loop suggested)

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
