Overview

Z.AI's flagship open-weights model — a post-trained upgrade of GLM-5.2 (same MoE base) with major gains in coding and long-horizon agentic work. Text-only, 1M-token context, 128K max output; reasoning is always on with selectable effort. $1.40/$4.40 per 1M tokens; cached input $0.26. Weights are published at huggingface.co/zai-org/GLM-5.3 (with a BF16 twin), under the GLM-5.3 License.

Run it yourself

Deploy this open model on rented GPUs

Open weights mean you can self-host instead of paying per-token API prices. These platforms let you serve it on demand — often cheaper at scale.
