# GLM-4.5-Air

> Use GLM-4.5-Air with NeMo AutoModel for language model fine-tuning, with documented checkpoints, runnable recipes, setup guidance, and model reference details.

[GLM-4.5 and GLM-4.7](https://huggingface.co/zai-org) are Mixture-of-Experts variants of the GLM family released under the `zai-org` HuggingFace organization. GLM-4.7-Flash is a lighter variant with fewer active parameters.

Set up NeMo AutoModel with the [latest container](https://catalog.ngc.nvidia.com/orgs/nvidia/containers/nemo-automodel) or follow the [installation instructions](/get-started/installation).

## Fine-Tune GLM-4.5-Air

> **Note**
>
> This recipe was validated on **8 nodes x 8 GPUs (64 H100s)**. See the [Launcher Guide](/job-launchers/slurm-cluster) for multi-node setup.

From the repository root, run:

```bash
uv run automodel --nproc-per-node=8 examples/llm_finetune/glm/glm_4.5_air_te_deepep.yaml
```
