Zhipu AI

A Chinese AI company, spun out of Tsinghua University's Knowledge Engineering Group, that develops the General Language Model (GLM) family of large language modelslarge language model, n.: A computer program trained on enormous amounts of text to predict the words that come next. At vast scale, that simple skill lets it chat, answer questions, translate, summarize and write code. and the ChatGLM and Z.ai assistants. Its GLM pretraining method (2021) unified bidirectional and autoregressive language modelinglanguage model, n.: A system that has learned how likely different sequences of words are, so it can predict the next word in a text and, by doing that repeatedly, write text of its own. through blank infilling; the bilingual GLM-130B (2022) was among the first openly released models with over 100 billion parameters, and ChatGLM-6B (2023) was widely run on consumer hardware. Later open-weightopen-weight model, n.: An AI model whose trained internal numbers are published for anyone to download and run on their own computers, even if the data and code used to make it stay private. releases, such as GLM-4.5 (July 2025) and GLM-5 (February 2026), targeted coding and agent tasks. In January 2025 the US Commerce Department added it to the Entity List, restricting American exports to it, and in January 2026 it became the first of China's large-model startups to list on the Hong Kong Stock Exchange.
