The [AutoGPTQ](https://github.com/PanQiWei/AutoGPTQ) library implements the GPTQ algorithm, a post-training quantization technique where each row of the weight matrix is quantized independently to find a version of the weights that minimizes the error. These weights are quantized to int4, but they're restored to fp16 on the fly during inference. This can save your memory-usage by 4x because the int4 weights are dequantized in a fused kernel rather than a GPU's global memory, and you can also expect a speedup in inference because using a lower bitwidth takes less time to communicate.

Both [GPTQModel](https://github.com/ModelCloud/GPTQModel) and [AutoGPTQ](https://github.com/PanQiWei/AutoGPTQ) libraries implement the GPTQ algorithm, a post-training quantization technique where each row of the weight matrix is quantized independently to find a version of the weights that minimizes error. These weights are quantized to int4, stored as int32 (int4 x 8) and dequantized (restored) to fp16 on the fly during inference. This can save memory by almost 4x because the int4 weights are often dequantized in a fused kernel. You can also expect a substantial speedup in inference due to lower bandwidth requirements for lower bitwidth.

|
||||
[GPTQModel](https://github.com/ModelCloud/GPTQModel) started as a maintained fork of AutoGPTQ but has since differentiated itself with the following major differences.
|
||||
|
||||
* Model support: GPTQModel continues to support all of the latest LLM models.
|
||||
* Multimodal support: GPTQModel supports accurate quantization of Qwen 2-VL and Ovis 1.6-VL image-to-text models.
|
||||
* Platform support: Linux, macOS (Apple Silicon), and Windows 11.
|
||||
* Hardware support: NVIDIA CUDA, AMD ROCm, Apple Silicon M1/MPS /CPU, Intel/AMD CPU, and Intel Datacenter Max/Arc GPUs.
|
||||
* Asymmetric support: Asymmetric quantization can potentially introduce lower quantization errors compared to symmetric quantization. However, it is not backward compatible with AutoGPTQ, and not all kernels, such as Marlin, support asymmetric quantization.
|
||||
* IPEX kernel for Intel/AMD accelerated CPU and Intel GPU (Datacenter Max/Arc GPUs) support.
|
||||
* Updated Marlin kernel from Neural Magic optimized for A100 (Ampere).
|
||||
* Updated kernels with auto-padding for legacy model support and models with non-uniform in/out-features.
|
||||
* Faster quantization, lower memory usage, and more accurate default quantization via GPTQModel quantization APIs.
|
||||
* User and developer friendly APIs.
|
||||
|
||||
|
||||
[AutoGPTQ](https://github.com/PanQiWei/AutoGPTQ) will likely be deprecated in the future due the lack of continued support for new models and features.
|
||||
|
||||
Before you begin, make sure the following libraries are installed and updated to the latest release:
|
||||
|
||||
```bash
|
||||
pip install auto-gptq
|
||||
pip install --upgrade accelerate optimum transformers
|
||||
```
|
||||
|
||||
Then install either GPTQModel or AutoGPTQ.
|
||||
|
||||
```bash
|
||||
pip install gptqmodel --no-build-isolation
|
||||
```
|
||||

```bash
|
||||
pip install auto-gptq --no-build-isolation
|
||||
```
|
||||
|
||||
To quantize a model (currently only supported for text models), you need to create a [`GPTQConfig`] class and set the number of bits to quantize to, a dataset to calibrate the weights for quantization, and a tokenizer to prepare the dataset.

## Marlin
|
||||
|
||||
[Marlin](https://github.com/IST-DASLab/marlin) is a 4-bit only CUDA GPTQ kernel, highly optimized for the NVIDIA A100 GPU (Ampere) architecture. Loading, dequantization, and execution of post-dequantized weights are highly parallelized, offering a substantial inference improvement versus the original CUDA GPTQ kernel. Marlin is only available for quantized inference and does not support model quantization.
|
||||
|
||||
Marlin inference can be activated with the `backend` parameter in [`GPTQConfig`].

||||

||||
```py

[ExLlama](https://github.com/turboderp/exllama) is a Python/C++/CUDA implementation of the [Llama](model_doc/llama) model that is designed for faster inference with 4-bit GPTQ weights (check out these [benchmarks](https://github.com/huggingface/optimum/tree/main/tests/benchmark#gptq-benchmark)). The ExLlama kernel is activated by default when you create a [`GPTQConfig`] object. To boost inference speed even further, use the [ExLlamaV2](https://github.com/turboderp/exllamav2) kernels by configuring the `exllama_config` parameter:

The ExLlama kernels are only supported when the entire model is on the GPU. If you're doing inference on a CPU with AutoGPTQ (version > 0.4.2), then you'll need to disable the ExLlama kernel.
