Zhipu has formally introduced the GLM-5.3 model. This new model is built upon the same foundational architecture as its predecessor, GLM-5.2. However, it has undergone extensive post-training to substantially boost its intelligence. In the realm of programming, GLM-5.3 has demonstrated exceptional performance. Its score on Terminal-Bench 3.0 has skyrocketed from 4.6 to 28.3. Similarly, its score on DeepSWE v1.1 has seen a notable increase, jumping from 46.2 to 66.9, thereby securing the top position among open-source models.
