GLM-5 / GLM-5.1 (MoE + DSA)

View as Markdown

GLM-5 and GLM-5.1 are Zhipu AI’s latest open-source large Mixture-of-Experts models featuring a DeepSeek-style MLA (Multi-head Latent Attention) + DSA (Dynamic Sparse Attention) architecture. GLM-5.1 shares the glm_moe_dsa architecture with GLM-5, with updated weights.

Try with NeMo AutoModel

1. Install (full instructions):

$pip install nemo-automodel

2. Clone the repo to get the example recipes:

$git clone https://github.com/NVIDIA-NeMo/Automodel.git
$cd Automodel

This recipe was validated on 32 nodes × 8 GPUs (256 H100s). See the Launcher Guide for multi-node setup.

3. Run the recipe from inside the repo:

$automodel --nproc-per-node=8 examples/llm_finetune/glm/glm_5_hellaswag_pp.yaml

1. Pull the container and mount a checkpoint directory:

$docker run --gpus all -it --rm \
>  --shm-size=8g \
>  -v $(pwd)/checkpoints:/opt/Automodel/checkpoints \
>  nvcr.io/nvidia/nemo-automodel:26.04.00

2. Navigate to the AutoModel directory (where the recipes are):

$cd /opt/Automodel

3. Run the recipe:

$automodel --nproc-per-node=8 examples/llm_finetune/glm/glm_5_hellaswag_pp.yaml
