Zhipu AI has released its flagship open-source model, GLM-5.2, which supports a 1 million token context window and has demonstrated top performance in coding and long-range tasks. This release follows Anthropic's temporary withdrawal of its Claude Fable 5 and Mythos 5 models, positioning GLM-5.2 as an accessible, commercially usable alternative. Elon Musk predicted that Chinese AI models could reach Fable 5's level within a quarter, a timeline Zhipu AI's founder suggested is even shorter, highlighting the rapid advancement and increasing global influence of Chinese AI development.
