This model was built with GLM-5.2 model by applying [AMD-Quark](https://quark.docs.amd.com/latest/index.html) for MXFP4 quantization.

# Model Quantization

The model was quantized from [zai-org/GLM-5.2](https://huggingface.co/zai-org/GLM-5.2) using [AMD-Quark](https://quark.docs.amd.com/latest/index.html). The weights and activations are quantized to MXFP4.

**Quantization scripts:**

```bash
cd Quark/examples/torch/language_modeling/llm_ptq/
  python quantize_quark.py \
      --model_dir zai-org/GLM-5.2 \
      --output_dir GLM-5.2-MXFP4 \
      --quant_scheme mxfp4 \
      --exclude_layers "*self_attn*" "*mlp.gate" "*lm_head" \
          "*mlp.gate_proj" "*mlp.up_proj" "*mlp.down_proj" \
          "*layers.78.*" \  # Exclude the MTP layer (layer 78)
      --file2file_quantization
```

# Deployment
### Use with SGLang/vLLM

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

## Evaluation
The model was evaluated on GSM8K benchmarks.

  </tr>
</table>

### Reproduction

The GSM8K results were obtained using the `lm-evaluation-harness` framework, based on the Docker image `lmsysorg/sglang:v0.5.13.post1-rocm700-mi35x`, with SGLang pre-installed inside the image and lm-eval compiled and installed from source.

```
lm_eval --model sglang \
    --model_args pretrained=amd/GLM-5.2-MXFP4,tp_size=4 \
    --tasks gsm8k \
    --batch_size auto
```

The Docker image `rocm/vllm-dev:nightly_main_20260616` with vLLM pre-installed can also be used for reproducing using vLLM backend.

```
export VLLM_ROCM_USE_AITER=1
export VLLM_ROCM_USE_AITER_FP8BMM=0
export VLLM_ROCM_USE_AITER_FP4BMM=0
lm_eval --model vllm \
    --model_args 'pretrained=amd/GLM-5.2-MXFP4,tensor_parallel_size=4,dtype=auto,quantization='quark',gpu_memory_utilization=0.9,max_model_len=32768,trust_remote_code=True' \
    --tasks gsm8k \
    --batch_size auto
```
