OpenAI’s chip chief tells More Than Moore he doesn’t fully trust AI design

OpenAI’s own AI models changed parts of its Jalapeño chip, and its engineers could not always say why. In one example, they saved more than 13% of die area, Richard Ho told Ian Cutress of More Than Moore. Ho leads OpenAI’s hardware team, and the interview was published on 30 September. OpenAI revealed its own AI chip in June. It built the chip with Broadcom to run its models, not to train them. At Hot Chips in August, it showed benchmark results against Nvidia’s GB300. The interview is about how the chip was made. Ho joined OpenAI in 2023. He was one of the first engineers on Google’s TPU programme. Before that, he built the Anton supercomputers at D.E. Shaw Research. The team moved fast, Ho said.
