ByteDance is in talks with Tianshu Zhixin to buy at least 50,000 AI chips, sources say, primarily for inference workloads. The chips discussed are Tianshu Zhixin’s ZhiKai cloud inference GPUs; its Tiangai series would be used for training. If completed, Tianshu Zhixin would become ByteDance’s third GPU supplier after Huawei and Cambricon. ByteDance and Tianshu Zhixin had no immediate comment.

If completed, Tianshu Zhixin would become ByteDance’s third GPU supplier after Huawei and Cambricon. ByteDance and Tianshu Zhixin had no immediate comment. The deal and broader moves by Chinese internet giants to expand in‑house data centers signal a structural shift: AI compute demand is bifurcating between training and inference, firms are accelerating self‑controlled compute strategies, and large‑scale domestic compute substitution and separate training/inference hardware deployment are entering execution.
