ChainCatcher report: Zhizhang (02513.HK), listed in Hong Kong, surged significantly during today’s trading session, rising over 45% at its peak to HK$1,620.00; the gain has since narrowed to approximately 28%, with the current price at HK$1,404.00. In response to the unusual price movement, Zhizhang issued a statement indicating that it is unaware of any inside information requiring disclosure. On the news front, against the backdrop of its overseas competitors’ most advanced models being globally banned due to government regulations, Zhizhang has announced the launch of its latest flagship model, GLM-5.2. This model supports context lengths of up to 1M and will be fully open-sourced next week under the MIT license. Zhizhang stated that this move aims to attract global developers through an open strategy, and expects the model’s release to significantly boost usage on its subsequent open platform and API services.
