(Yicai) Feb. 12 -- Shares of Knowledge Atlas Technology Joint Stock, also known as Zhipu AI, surged after the Chinese artificial intelligence startup released its new flagship open-sourced foundation model GLM-5.

Zhipu AI [HKG: 2513] closed 29 percent higher at HKD402 (USD51.43) a share in Hong Kong today, after earlier surging by as much as 42 percent. The stock has surged 235 percent since its first day of trading on Jan. 8.

GLM-5 focuses on enhancing programming and agent capabilities, supporting larger model sizes and more complex reinforcement learning tasks, Zhipu AI noted. It has an asynchronous agent reinforcement learning algorithm, enabling the model to continuously learn from long-range interactions.

The mysterious Pony Alpha model, which topped OpenRouter's popularity model rankings earlier this week, was the new GLM-5, Zhipu AI told Yicai.

For the first time, GLM-5 integrates DeepSeek Sparse Attention, a sparse attention mechanism, maintaining the quality of long text processing without loss while significantly reducing the deployment cost of the model, Zhipu AI.

AI model updates this year have shown that they have evolved from writing code and front-end to handling engineering tasks and completing large projects. GLM-5's performance in real programming scenarios is approaching that of Anthropic's Claude Opus 4.5, while excelling in complex system engineering and long-range agent tasks.

In addition, GLM-5 can be integrated into the viral open-source AI agent system OpenClaw to give users an intelligent intern to perform various tasks, including searching websites, organizing information, posting tweets, and handling programming tasks.
