Shares of Chinese

AI giant Z.ai

soared 37 per cent in Hong Kong on Tuesday to close at HK$1,219 (US$155), after the company recently completed a giant data centre powered entirely by Chinese chips.

Also known as Zhipu, the firm’s share prices rebounded after a week-long drop of more than 40 per cent. According to people familiar with the matter, it had built a giant 1-gigawatt AI computing centre – a facility that will be used to train and deploy its GLM models. The company has positioned its flagship

GLM-5.2

as one of China’s leading large language models (LLMs).

Meanwhile, the Beijing-based company had also completed the acquisition of Chinese infrastructure software developer XCore Sigma, a company spun off from the Chinese Academy of Sciences, the interviewees said.

XCore Sigma focuses on heterogeneous computing software, including compilers, runtime systems and inference engines that help improve the utilisation of AI chips from different vendors, reduce inference costs and accelerate model deployment.

Z.ai did not immediately respond to a request for comment on Tuesday.

The move, together with the new data centre, is set to address computing power constraints and improve AI inference efficiency for Z.ai.
