Zhipu AI's GLM-5.2 closes in on closed-source leaders in coding marathons

Zhipu AI has released GLM-5.2, an open-source model featuring a stable 1-million-token context, under the MIT license. In the FrontierSWE benchmark for coding tasks, GLM-5.2 closely competes with Anthropic's Claude Opus 4.8, trailing by only one percentage point, although it still lags behind closed-source models in reasoning capabilities. This advancement is significant for practitioners as it demonstrates the growing competitiveness of open-source models in complex coding scenarios.
