Z.ai Shares Jump After Launching AI Model Powered by Chinese Chips

Chinese artificial intelligence company Z.ai, also known as Zhipu AI, saw its Hong Kong-listed shares climb more than 8% after unveiling a new artificial intelligence model that the company says can operate at scale using domestically developed Chinese chips.

The development highlights China's accelerating push to reduce its dependence on foreign semiconductor technology as restrictions continue to affect access to advanced US-designed processors.

Z.ai Introduces GLM-5.3-Flash

The new model, called GLM-5.3-Flash, is positioned as a lower-cost member of Z.ai's GLM-5 model family.

Z.ai said the system combines 320 billion total parameters with 18 billion active parameters, aiming to deliver stronger performance while requiring less computing power.

The company said GLM-5.3-Flash had previously been tested anonymously under the name “ox-alpha” before its official release.

According to Z.ai, traffic generated during the testing period was served using Chinese AI accelerators. The company said its infrastructure was designed to overcome limitations in individual chips through software optimisation and large-scale clustering.

China Pushes for Domestic AI Infrastructure

The announcement comes as Chinese technology companies increase investment in locally developed semiconductors.

Restrictions imposed by Washington have limited China's access to some of the world's most advanced AI processors, while Beijing has encouraged domestic companies to strengthen homegrown alternatives.

Huawei and several Chinese semiconductor developers have been working to build processors capable of supporting increasingly demanding artificial intelligence applications.

Z.ai's latest deployment suggests Chinese AI companies are also focusing on improving software and infrastructure efficiency to extract greater performance from domestic hardware.

The company claims its serving system has achieved performance and per-token costs comparable with mainstream Nvidia GPU infrastructure on the hardware it tested.

Chinese AI Stocks Draw Investor Attention

Z.ai has attracted significant investor interest since listing in Hong Kong in January 2026.

The company priced its IPO at HK$116.20 per share and raised more than HK$4.3 billion during its market debut.

Investor enthusiasm around China's AI sector has also benefited rival MiniMax.

MiniMax reported $116.6 million in revenue during the first half of 2026, representing an increase of 283.1% year over year. However, its adjusted net loss widened to approximately $293 million during the same period.

Competition in AI Computing Intensifies

The launch of GLM-5.3-Flash adds another dimension to the global competition surrounding artificial intelligence infrastructure.

While Nvidia remains dominant in advanced AI computing, Chinese companies are increasingly attempting to build an independent ecosystem combining domestic chips, AI models and specialised software.

For Z.ai, demonstrating that advanced models can be efficiently deployed using Chinese hardware could prove strategically important as China continues pursuing greater technological self-sufficiency.

The development also signals that competition in artificial intelligence is expanding beyond model performance alone, with computing costs, chip availability and infrastructure efficiency becoming increasingly important factors.
