Stock Movement | Zhipu surges over 10% with the release of open-source model GLM-5.1

General-purpose AI model developer Zhisu (02513) has released its next-generation open-source model GLM-5.1 and raised GLM’s price against the market trend. The stock price jumped by more than 10%, rising as much as 18.7%, reaching a high of 925 yuan.

As of 3:11 pm, it was at 884 yuan, up 13.5%, with turnover of 2.1 billion yuan.

Mainland media reported that Zhisu officially released the next-generation open-source model GLM-5.1. According to OpenRouter, with this launch, Zhisu’s GLM was priced 10% higher again. After the price adjustment, the cached hit token price of GLM-5.1 in Coding scenarios is close to the level of Anthropic’s Claude Sonnet 4.6 in the United States.

On programming capability, GLM-5.1 continues to maintain a leading position. In the integrated average scores across the three code evaluation benchmarks SWE-bench Pro, Terminal-Bench, and NL2Repo, it achieved third globally, first among domestic models, and first among open-source models. In the SWE-bench Pro benchmark test—the one closest to real software development—it even marked the first time a domestic model surpassed Opus 4.6, setting a new global best result.

In addition, it has also made breakthroughs in long-horizon tasks. GLM-5.1 is the only open-source model that reaches 8 hours of continuous operation, and it is also one of the few models worldwide—apart from Claude Opus 4.6—that have this long-range capability. GLM-5.1 breaks through the current limitation of large models being mainly focused on minute-level interactions. It can continue working—autonomously and for up to 8 hours—on a single task. During the process, it autonomously breaks down the task, repeatedly experiments and tries out iterations, fixes problems, and ultimately delivers complete engineering-grade results.
