 ## Deployment
-Quark has its own export format and allows FP8 quantized models to be efficiently deployed using the vLLM backend(vllm-compatible).

 ## Evaluation
 Quark currently uses perplexity(PPL) as the evaluation metric for accuracy loss before and after quantization.The specific PPL algorithm can be referenced in the quantize_quark.py.
