Quantized Qwen2.5-1.5B-Instruct

This repository contains 8-bit and 4-bit quantized versions of the Qwen2.5-1.5B-Instruct model using GPTQ. Quantization significantly reduces the model's size and memory footprint, enabling faster inference on resource-constrained devices while maintaining reasonable performance.

Model Description

The Qwen2.5-1.5B-Instruct is a powerful language model developed by Qwen for instructional tasks. These quantized versions offer a more efficient way to deploy and utilize this model.

Quantization Details

• Quantization Method: GPTQ (Generative Pretrained Transformer Quantization)
• Quantization Bits: 8-bit and 4-bit versions available.
• Dataset: The model was quantized using a subset of the "fka/awesome-chatgpt-prompts" dataset.

Usage

To use the quantized models, follow these steps:

Install Dependencies:

pip install transformers accelerate bitsandbytes auto-gptq optimum

Performance

The quantized models offer a significant reduction in size and memory usage compared to the original model. While there might be a slight decrease in performance, the trade-off is often beneficial for deployment on devices with limited resources.

Disclaimer

These quantized models are provided for research and experimentation purposes. We do not guarantee their performance or suitability for specific applications.
