GLM-5.3 Programming Capabilities Surge 50% Over GLM-5.2

Zhipu launches GLM-5.3 with unchanged base model but enhanced post-training, achieving 50% programming gains and leading open-source benchmarks like Terminal Bench3.0.

Woofun AI reports that Zhipu (HK2513) has officially released the GLM-5.3 model. While the base model architecture remains identical to GLM-5.2, advanced post-training scaling techniques have significantly boosted intelligent capabilities. The new iteration demonstrates a 50% improvement in internal sensory evaluation tasks for programming and ranks first among open-source models in public benchmarks, including Terminal Bench3.0 and Agents'Last Exam (CLI). Zhipu (HK2513) confirmed that model weights will be made available two weeks after release.
