glm-5.3

GLM‑5.3 inherits the base model of GLM‑5.2, with all capability improvements derived from large‑scale post‑training. It achieves top‑tier open‑source model performance in code development, long‑cycle agent tasks, and cybersecurity. Compared with its predecessor GLM‑5.2, it produces more compact token outputs for equivalent engineering tasks, with a 50% improvement in coding benchmark scores and greatly enhanced vulnerability‑hunting security capabilities. Built for complex engineering and long‑c
