Shares of Zhipu AI, a leading Beijing-based artificial intelligence company, experienced a significant surge on Monday following the release of their latest large language model, GLM-5.2. This powerful model, set to be available on an open-source basis later this week, prompted the Hong Kong-listed stock to jump by as much as 48 percent in morning trading, eventually closing the day with a 32.8 percent increase at HK$1,457. The timing of this open-source launch coincided with a sudden decision by Washington to halt the deployment of top US models overseas.
Operating under the name Knowledge Atlas Technology, the company has seen its stock price rise by nearly 820 percent since its initial public offering in January. The GLM-5.2 model, notable for its extensive 1-million-token context window, was fully unveiled on Saturday.
This development highlights a growing trend among Chinese companies to attract users seeking alternatives to expensive Western models amid geopolitical tensions. Zhipu’s announcement closely followed the suspension of access to flagship models by US AI giant Anthropic, which cited a US government directive based on national security concerns.
The GLM-5.2 model will be accessible to subscribers of Zhipu’s new GLM Coding Plan, priced significantly lower than Anthropic’s premium offerings. The model’s API is expected to go live this week, with plans to open-source the model under the permissive MIT license.
