AI-built Redwood chip reaches hardware in two weeks as report says OpenAI engineers can no longer parse every line of AI-written code
A new report ties together two developments that point in the same direction for advanced computing: AI is moving from assisting engineers to handling core low-level work that humans may not fully inspect line by line. Citing SemiAnalysis, the story says OpenAI engineers reviewing low-level code for the company’s in-house chip effort admitted they could not fully explain how every AI-generated assembly sequence worked, even though the code had been tested and delivered strong performance. The report also says OpenAI built a low-level kernel programming language called Gluon on top of Triton, with complex hardware instructions generated by AI. At the same time, Architect Labs has released a preprint titled "Redwood: A Frontier AI Accelerator Designed, Verified, and Deployed from Scratch in 2 Weeks by AI." According to the paper, two human engineers wrote high-level functional specifications in natural language, and an AI system produced the hardware design, verification suite, and firmware stack in two weeks without using off-the-shelf commercial accelerator IP. The paper says Redwood was deployed on AMD Xilinx Versal FPGA hardware and ran an open-source large model. It also estimates that if Redwood were converted into an ASIC on an equivalent process node, its energy efficiency in edge Physical AI and low-power settings would be 3.4 times that of Nvidia Jetson. The paper further says a model running on the first-generation Redwood chip has already joined the design of the next generation.
