Z.ai

Z.ai, formally Knowledge Atlas Technology Joint Stock Co., Ltd., is a Chinese technology company specializing in artificial intelligence. Previously known internationally as Zhipu AI, the company rebranded to Z.ai in 2025. Its core focus is the GLM family of…

GLM 5.2 is Z.ai's next-generation large language model and the newest entry in the company's flagship GLM line, released in June 2026. Built by the Chinese AI firm formerly known as Zhipu AI, it advances the series with significantly stronger reasoning, sharper instruction following, and broad multilingual support, all served under the permissive MIT License that Z.ai has applied to GLM releases since mid-2025.

Within the lineup, GLM 5.2 sits at the top of the core GLM family, succeeding GLM 5.1 (April 2026) and the earlier GLM 5 and GLM 4.7 generations. It pairs a roomy 200K-token context window with fp8 quantization for efficient, fast inference, and ships with reasoning, function-calling, and web-search capabilities baked in.

That combination makes GLM 5.2 well suited to demanding work: long-document analysis, multi-step reasoning tasks, tool-augmented agents, and multilingual applications where an open, MIT-licensed model is preferred. Users wanting the most capable current GLM should reach for this release, while older siblings remain available for those balancing cost or speed.
