(Bloomberg) -- OpenAI is working with Broadcom Inc. to develop a new artificial intelligence chip specifically focused on running AI models after they’ve been trained, according to two people familiar with the matter.

The AI startup and chipmaker are also consulting with Taiwan Semiconductor Manufacturing Co., the world’s largest chip contract manufacturer, said the people, who asked not to be identified because the discussions are private. OpenAI has been planning a custom chip and working on such uses for the technology for around a year, the people said, but the discussions are still at an early stage.

OpenAI declined to comment. A representative for Broadcom didn’t respond to a request for comment, and a TSMC spokesperson said the company doesn’t comment on rumors and speculation. Reuters reported on OpenAI’s ongoing talks with Broadcom and TSMC on Tuesday. The Information reported in June that Broadcom had discussed making an AI chip for OpenAI.

The process for taking a chip from design to production is long and expensive. OpenAI is less focused on graphics processing units, chips that are used to train and build generative AI models — a market that has been cornered by Nvidia Corp. Instead, it’s looking for a specialized chip that will run the software and respond to user requests, a process called inference. Investors and analysts expect the need for chips to support inference will only grow as more tech companies use AI models to field more complex tasks.

OpenAI may continue to research setting up its own network of foundries, or chip factories, one of the people said, but the startup has realized that working with partners on custom chips is a quicker, attainable path for now. Reuters earlier reported that OpenAI was pulling back from the effort of establishing its own chip manufacturing capacity.

Broadcom shares closed up 4.2% to $179.24 in New York trading on Tuesday. Even before the latest gain, they were up 54% this year. TSMC’s US-traded shares closed more than 1% higher.

Broadcom is the largest designer of application-specific integrated circuits — chips designed to fit a single purpose specified by the customer. The company’s biggest customer in this area is Alphabet Inc.’s Google. Broadcom also works with Meta Platforms Inc. and TikTok owner ByteDance Ltd.
