GLM-4.5-Air-GPTQ-Int4-Int8Mix

Base model: 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.
