Greg Brockman says OpenAI's tech found chip optimizations that would've taken humans weeks

"Brockman said on an episode of "The OpenAI Podcast" published Monday that the company's models helped uncover chip design optimizations that would have taken human designers weeks to identify. "We've been able to apply our own models to designing this chip," Brockman said, referring to OpenAI's new custom silicon developed in partnership with Broadcom. "You take components that humans have already optimized and just pour compute into it, and the model comes up with its own optimizations," he added."

"Brockman said the AI-assisted process led to "massive area reductions" on the chip - meaning smaller, more efficient hardware - and shaved weeks off the production schedule. "I don't think any of the optimizations that we have are ones that human designers couldn't have come up with," he said. "Our experts take a look at it later, and say, 'Yeah, this was on my list,' but it was like, 20 things that would've taken them another month to get to," he added."

OpenAI applied its AI models to co-design custom silicon with Broadcom, enabling rapid discovery of chip-design optimizations that would have taken human engineers weeks. The AI-driven process produced significant area reductions, yielding smaller, more efficient chips and shortening production schedules by weeks. Experts later confirmed many of the optimizations were expected, but the models surfaced about twenty items that would have taken an additional month to find. OpenAI is building in-house expertise to understand chip design and is partnering with Broadcom to deploy ten gigawatts of custom chips across facilities and partner data centers between 2026 and 2029.
