Z.ai
A Chinese AI company (formerly Zhipu AI) behind the GLM model family.
Z.ai, formerly known as Zhipu AI, is one of China’s leading AI companies. Its GLM model family competes with Western frontier models, and recent versions are released with open weights at aggressive prices.
Together with DeepSeek and Alibaba’s Qwen team, Z.ai is part of the wave of Chinese labs that made capable open models a normal, everyday option.
