Z.AI (智谱AI) : China's lab spun from Tsinghua's KEG to build open-source GLM foundation models.

Z.AI was founded in 2019 from Tsinghua University's knowledge-engineering lab and trains the GLM family of large language models — a role Western users can liken to OpenAI.

Its models reach users as a chatbot, a developer API, and open-source releases; Z.AI shipped China's first open-sourced 100-billion-parameter model in 2022.

Because GLM models are open-sourced, developers outside China can download and run them locally, and newer releases add coding and AI-agent abilities.

What sets GLM-5.2 apart from other Chinese LLMs?

GLM-5.2 is open-source SOTA for coding with 1M-token lossless context, backed by a full agent ecosystem including AutoGLM for autonomous execution and AutoClaw for PC-level control. It offers free tiers (GLM-4.7-Flash) and spans text, vision, video, and OCR — a full-stack offering rare among Chinese models.

What is Zhipu AI's relationship with Tsinghua University?

Zhipu AI was founded by researchers from Tsinghua University's Knowledge Engineering Group. It maintains close ties with Tsinghua for research collaboration. This academic background gives GLM strong credentials in the Chinese AI research community.

Can I access GLM (ChatGLM) from the US?

ChatGLM is accessible at zhipuai.cn with Chinese phone registration. The open-source GLM models are available on Hugging Face for global download. The commercial API primarily serves Chinese enterprises but international access is possible.
