ByteDance to develop custom CPUs for AI amid chip shortages

Chinese technology company ByteDance is developing its own central processing units to support its artificial intelligence infrastructure, according to people familiar with the matter. The move is a response to rising chip prices and supply shortages that have constrained the company's expansion plans.

The project places ByteDance among a growing number of global technology firms, including Google, Amazon, and Microsoft, that are designing custom CPUs. This industry shift is driven by the demands of AI inference, where deployed models perform tasks that require significant processing power from CPUs working alongside specialized graphics chips. The trend has contributed to a recent shortage of server CPUs.

ByteDance is pursuing the development to reduce costs and tailor performance for its specific workloads, particularly as it prepares for a major rollout of agent-based AI products. The company currently sources its CPUs from Intel and AMD, but sources indicate those suppliers have significantly raised prices in recent months, with increases ranging from 10 to 35 percent quarter-over-quarter. This pricing pressure has accelerated ByteDance's push for in-house alternatives.
