Meta Platforms plans to begin deploying a new in-house artificial intelligence chip in data centers during the first half of next year, a move it says will save money and energy when running AI models.

Meta shares rose 1.2% in morning trading.

The company, which first announced plans to develop homegrown AI chips in 2023, is testing the third generation of the line, called MTIA 450, or Arke. The next one — dubbed 500, or Astrid — will complete design work in about a month and go into data centers at the end of 2027. Meta expects to use that one even more widely.

“Each one takes on a little bit more risk technologically, and gets us better performance,” Yee Jiun Song, Meta’s vice president of engineering, said in an interview. That includes better performance per watt of energy and per dollar spent, he said.

Meta, the owner of Facebook, Instagram and WhatsApp, is developing its own chips as part of a massive push to develop AI infrastructure. The company is working with Broadcom Inc. on the designs and Taiwan Semiconductor Manufacturing Co. on manufacturing — a project aimed at reducing its reliance on Nvidia Corp.’s industry-leading processors.
