ByteDance develops proprietary AI chip amid US concerns over Chinese AI advances

ByteDance, the Chinese owner of TikTok and Douyin, is accelerating the creation of an in‑house AI accelerator for its data‑center workloads. The goal is to reduce reliance on external GPUs, particularly NVIDIA, by designing silicon optimized for the company's own language‑model training and inference. Sources indicate possible collaborations with Broadcom for design and TSMC for manufacturing, aiming for lower energy use, cost savings and supply‑chain security.

Across the Pacific, leading Silicon Valley firms warn that Chinese AI companies are rapidly closing the technology gap. Using techniques such as model "distillation" and launching powerful models like the GLM‑5.2, experts estimate the U.S. advantage has shrunk to about six months. This has prompted calls for tighter export controls on advanced chips and legislative action to protect U.S. strategic interests in AI, highlighting intensified competition between the United States and China.
