Podcast: Z.ai, Inside One of China's Top AI Companies
Z.ai, a leading Chinese AI lab behind the GLM foundation models, announced its upcoming flagship model GLM‑5.1. The new model matches the performance of OpenAI’s Opus 4.6 on coding and agentic tasks while delivering roughly double the results on long‑horizon workloads. Z.ai achieved these gains without changing the underlying architecture, instead focusing on new long‑horizon datasets, iterative training and enhanced tool‑calling. The company also highlighted its hardware co‑design with Chinese chipmakers and its flexible open‑source strategy as part of a broader push to compete globally.
