- GLM-5.3 uses the same base model as GLM-5.2 — every gain comes from post-training.
- Compared with GLM-5.2, it is much better at complex coding and long-horizon tasks: Stronger Coding: GLM-5.3 is the most capable open-weights model for coding, with a 50% improvement over GLM-5.2 on our in-house Z.ai Code Bench.
- It also achieve open-source SOTA on public benchmarks including Terminal Bench 3.0 and Agents' Last Exam.
