The model published in this repo was quantized to 4bit using AutoGPTQ.
Quantization details
All quantization parameters were taken from GPTQ paper.
GPTQ calibration data consisted of 128 random 2048 token segments from the C4 dataset.
The grouping size used for quantization is equal to 128.
How to use this GPTQ model from Python code
Install the necessary packages
Requires: Transformers 4.33.0 or later, Optimum 1.12.0 or later, and AutoGPTQ 0.4.2 or later.
shell
1pip3 install --upgrade transformers optimum
2# If using PyTorch 2.1 + CUDA 12.x:3pip3 install --upgrade auto-gptq
