# Grok-1-W4A8KV8 |
|
## 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", "*.gate" |
|
- ***Weight***: FP8 symmetric per-tensor, additionally, INT4 symmetric per-channel for MoE linear |
|
- ***Activation***: FP8 symmetric per-tensor |
|
- ***KV Cache***: FP8 symmetric per-tensor |
|
### INT4 Packing |
|
Every eight `int4` values are packed into a single `int32` integeter following the sequence defined by `order_map = [0, 2, 4, 6, 1, 3, 5, 7]`. |
|
## 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 lmzheng/grok-1 |
|
python3 quantize_quark.py \ |
|
--model_dir $MODEL_DIR \ |
|
--output_dir grok-1-W4A8KV8 \ |
|
--quant_scheme TBD \ |
|
--kv_cache_dtype fp8 \ |
|
--num_calib_data 128 \ |
|
--model_export hf_format \ |
|
--multi_gpu \ |
|
--custom_mode fp8 |
|
``` |
|
## Deployment |
|
Quark has its own export format and allows FP8 quantized models to be efficiently deployed using the SGLang backend. |
|
## 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. |
