Meta and Broadcom announced an expanded co-development agreement on April 14, extending through 2029 and committing to an initial deployment exceeding one gigawatt of custom MTIA (Meta Training and Inference Accelerator) chips—described as just the first phase of a sustained multi-gigawatt rollout. The chips will use a 2nm process, which Broadcom says will be the first 2nm AI compute accelerator in production. Under the deal, Broadcom's XPU platform will support four new MTIA chip generations over the next two years, with Broadcom CEO Hock Tan stepping down from Meta's board to take an advisory role on the custom silicon roadmap.
