# Model Quantization

The model was quantized from [zai-org/GLM-5.1](https://huggingface.co/zai-org/GLM-5.1) using [AMD-Quark](https://quark.docs.amd.com/latest/index.html). The weights and activations are quantized to NVFP4.

**Quantization scripts:**
```
sudo sysctl -w vm.max_map_count=4194304
cd Quark/examples/torch/language_modeling/llm_ptq/
export CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7
export MODEL_DIR=zai-org/GLM-5.1
export output_dir=amd/GLM-5.1-NVFP4
exclude_layers="*self_attn* *mlp.gate lm_head *mlp.gate_proj *mlp.up_proj *mlp.down_proj"
python3 quantize_quark.py --model_dir $MODEL_DIR \
                          --quant_scheme nvfp4 \
                          --num_calib_data 128 \
                          --exclude_layers $exclude_layers \
                          --model_export hf_format \
                          --output_dir $output_dir \
                          --multi_gpu balanced
```

# Deployment
### Use with vLLM

This model can be deployed efficiently using the [vLLM](https://docs.vllm.ai/en/latest/) backend.

## Evaluation
The model was evaluated on GSM8K benchmarks.

  </tr>

  </tr>
</table>

### Reproduction

The GSM8K result was obtained using the `lm-evaluation-harness` framework, based on the Docker image `rocm/vllm-dev:nightly_main_20260603`.

Install the lm-eval `(Version: 0.4.12)` in container first.
```
pip install lm-eval[api]
```

#### Launching server
```
export VLLM_ROCM_USE_AITER=1
export VLLM_ROCM_USE_AITER_FP8BMM=0
export VLLM_ROCM_USE_AITER_FP4BMM=0
HIP_VISIBLE_DEVICES=4,5,6,7 vllm serve amd/GLM-5.1-NVFP4 \
  -tp 4 \
  --block-size 1 \
  --trust-remote-code \
  --max-model-len 4096 \
  --port 8082
```

#### Evaluating model in a new terminal
```
lm_eval \
  --model local-completions \
  --model_args '{"model": "amd/GLM-5.1-NVFP4", "base_url": "http://localhost:8082/v1/completions", "num_concurrent": 32, "max_retries": 10, "max_gen_toks": 2048, "tokenizer_backend": null, "tokenized_requests": false}' \
  --tasks gsm8k \
  --batch_size auto \
  --num_fewshot 5 \
  --trust_remote_code
