What is Z.ai?
Z.ai is a chinese artificial intelligence startup originally founded in 2019 as a spin-off from Tsinghua University.
It was formerly known as Zhipu AI before rebranding to Z.ai in 2025.
It has become one of China’s so-called “AI Tigers”, and by 2024 was considered the third-largest LLM (large language model) player in China according to IDC.
Z.ai is backed by major investors including Alibaba, Tencent, Ant Group, Meituan, and Xiaomi, among some others. It is headquartered in Beijing,china.
It is optimized for Nvidia H20 GPUs and compatible with Huawei Ascend & Kirin chips.
Zhipu Ai
Z.ai (formerly Zhipu AI) was co-founded in 2019 by Tsinghua University professors Tang Jie and Li Juanzi—not Zhang Peng.
Z.ai early models
Zhipu AI launched ChatGLM-130B, one of the first open-source Chinese–English bilingual large language models, in 2022.
The company has since gained recognition as one of China’s leading AI startups, often referred to among the country’s “AI Tigers” (a group of top AI unicorns).
Breakthrough in LLMs (2022–2023)
Z.ai Launched the ChatGLM series — one of the first open-source Chinese–English bilingual LLMs—and began offering Model-as-a-Service (MaaS) platforms for developers and enterprises.
In 2023 it released GLM-4 and GLM-4-Plus, and launched the AI coding assistant CodeGeeX. And secured major investment from Alibaba, Tencent, Ant Group, Xiaomi, and Meituan.
In 2024, Z.ai introduced the text-to-video model Ying in July, an in October they released AutoGLM, a mobile AI-agent capable of multi-step tasks.In July 2025, Z.ai released its new GLM-4.5 series of AI models, with main model named, GLM-4.5 which has 355 billion parameters in total. They also released an smaller model called GLM-4.5 Air, it has 106 billion parameters in total
Z.ai vs OpenAI and Grok 4
Built on Mixture-of-Experts architecture with hybrid reasoning modes, it achieved 3rd place globally and 1st among open-source models.
On performance benches, GLM-4.5 secured third place globally, competing with OpenAI's o3 and xAI’s Grok 4, excelling in reasoning, coding, and autonomous task handling
Cost Efficiency and Hardware Savings
GLM-4.5 runs on just eight Nvidia H20 GPUs, whereas rivals like DeepSeek require double that.
The model’s pricing is highly competitive with just $0.11 per million input tokens and $0.28 per million output tokens, substantially cheaper than DeepSeek’s pricing (which stands at ~$0.14 and ~$2.19 respectively.
Marketed as China’s “cost-efficient AI” solution.
Global Expansion, Investment, and Geopolitical Dynamics:
OpenAI flagged Zhipu AI’s involvement in multiple state-backed contracts across Malaysia, Singapore, UAE, Saudi Arabia, and Kenya—part of China’s strategy to promote its AI standards globally.
Consequently, Z.ai was added to the U.S. Commerce Department’s Entity List, restricting access to American technology. Despite this, it continues to secure state and institutional backing.
China's Broader AI Strategy
In line with broader trends, China aims to triple AI chip production by 2026, with Huawei leading multiple fabrication facilities focused on AI processing hardware. This expansion supports firms like Z.ai in reducing reliance on foreign tech.
Partnership with Alibaba Cloud
In line with broader trends, China aims to triple AI chip production by 2026, with Huawei leading multiple fabrication facilities focused on AI processing hardware.
This expansion supports firms like Z.ai in reducing reliance on foreign tech.
In August 2025, Z.ai and Alibaba Cloud teamed up to release a new general-purpose AI agent for smartphones, tablets, and web platforms.
The agent can autonomously handle tasks like ordering food, booking hotels, managing apps, and generating media.
Multimodal Edge
• GLM-4.5V adds vision capabilities (image + text input).
• While it competes against, GPT-4.1 Omni and Grok-4V, but Z.ai is positioning this as a free / low-cost model to capture market share.
• It has a valuation of over $1 billion.
• Market position wise it stands at number one spot as open-source LLM firm in China, while globally it stands with top-3 competitor.
• Z.ai is a part of China’s AI self-sufficiency and global AI influence.
What makes Z.ai different from OpenAI, xAI, or DeepSeek?
• Z.ai stands out for being, cheaper (lowest token costs in the market).
• Hardware-efficient (needs fewer GPUs, runs on Huawei chips).
• Agent-focused (GLM-4.5 designed for AI agents with Alibaba partnership).
• Open-source bilingual (Chinese + English support).
• Aggressively expanding into emerging markets.
Why is Z.ai considered important for China?
Z.ai is considered important to China because it reduces reliance on U.S. tech by running on Huawei processors.
It aligns with China’s strategy for AI self-sufficiency, and is backed by state investors and leading tech firms (Alibaba, Tencent).
Z.ai has quickly evolved into one of the most influential Chinese AI companies, offering GLM-4.5, a powerful, affordable, and hardware-efficient model.
• Its focus on AI agents, bilingual open-source models, and Huawei hardware integration gives it a unique position in the global AI race.
• While challenges from U.S. sanctions and tough competition remain, Z.ai’s cost efficiency and strategic importance make it a serious global contender and a key driver of China’s AI independence strategy.
