This model was built with deepseek-ai DeepSeek-V3.2 model by applying AMD-Quark for MXFP4 quantization.

Model Quantization

The model was quantized from deepseek-ai/DeepSeek-V3.2 using AMD-Quark. Both weights and activations were quantized to MXFP4 format.

Deployment

This model can be deployed efficiently using the SGLang and vLLM backends.
