Key Info

A user reports that Qwen4 generated a complete CPU chip design from a single prompt in about five hours, covering design writing, testing, correctness proof, and the files a factory would need, and passing checks that foundries run.

Highlights

  • The design is explicitly not manufacturable yet: 19 safety violations remain, with no pins and no memory defined.
  • The workflow included self-testing and formal correctness checks rather than only code generation.
  • Output included the file format a fabrication facility would require.
  • The author frames the exercise as an attempt to push the model's limits, not a production-ready chip.
