Z.AI

Z.AI is the Chinese AI lab behind the GLM family of language models, with roots in the Tsinghua University–linked Zhipu AI venture. Releases like GLM-4.6 put it on the Open Weight map, and among Chinese labs it shares the stage with DeepSeek V3 and Qwen 3. Its models are known for multilingual strength and long context. As Chinese-origin products that demonstrate Open Source LLM capability, they get sustained industry attention.
