# GLM-4.5-Air-GPTQ-Int4-Int8Mix
Base model: [zai-org/GLM-4.5-Air](https://huggingface.co/zai-org/GLM-4.5-Air)
### 【vLLM Single Node with 8 GPUs Startup Command】
Note: You must use `--enable-expert-parallel` to start this model, otherwise the expert tensor TP will not divide evenly. This is required even for 2 GPUs.

## Model Introduction
The **GLM-4.5** series is a foundation model family designed specifically for agents. GLM-4.5 has **355 billion** total parameters, including **32 billion** active parameters. GLM-4.5-Air features a more compact design with **106 billion** total parameters and **12 billion** active parameters. GLM-4.5 models unify reasoning, encoding, and agent capabilities to meet the complex demands of agent-based applications.
Both GLM-4.5 and GLM-4.5-Air are hybrid reasoning models that offer two modes: a *thinking mode* for complex reasoning and tool use, and a *non-thinking mode* for instant response.
We have open-sourced the base models, hybrid reasoning models, and FP8 versions of GLM-4.5 and GLM-4.5-Air. They are released under the MIT open-source license, available for commercial use and secondary development.
In our comprehensive evaluation across 12 industry-standard benchmarks, GLM-4.5 achieved an outstanding score of **63.2**, ranking **3rd** among all proprietary and open-source models. Notably, GLM-4.5-Air maintained excellent efficiency while achieving a competitive score of **59.8**.
For more evaluation results, case studies, and technical details, please visit our [technical blog](https://z.ai/blog/glm-4.5). The full technical report will be released soon.
