+# c4ai-command-r-plus-FP8-KV
+- ## Introduction
+  This model was created by applying [Quark](https://quark.docs.amd.com/latest/index.html) with calibration samples from Pile dataset.
+- ## Quantization Stragegy
+  - ***Quantized Layers***: All linear layers excluding "lm_head"
+  - ***Weight***: FP8 symmetric per-tensor
+  - ***Activation***: FP8 symmetric per-tensor
+  - ***KV Cache***: FP8 symmetric  per-tensor
+- ## Quick Start
+1. [Download and install Quark](https://quark.docs.amd.com/latest/install.html)
+2. Run the quantization script in the example folder using the following command line:
+```sh
+export MODEL_DIR = [local model checkpoint folder] or CohereForAI/c4ai-command-r-plus
+# single GPU
+python3 quantize_quark.py \
+        --model_dir $MODEL_DIR \
+        --output_dir c4ai-command-r-plus-FP8-KV \
+        --quant_scheme w_fp8_a_fp8 \
+        --kv_cache_dtype fp8 \
+        --num_calib_data 128  \
+        --model_export quark_safetensors
+# If model size is too large for single GPU, please use multi GPU instead.
+python3 quantize_quark.py \
+        --model_dir $MODEL_DIR \
+        --output_dir c4ai-command-r-plus-FP8-KV \
+        --quant_scheme w_fp8_a_fp8 \
+        --kv_cache_dtype fp8 \
+        --num_calib_data 128  \
+        --model_export quark_safetensors \
+        --multi_gpu
+```
+## 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.
+The quantization evaluation results are conducted in pseudo-quantization mode, which may slightly differ from the actual quantized inference accuracy. These results are provided for reference only.
