PreSINQ GGUF Quantized Qwen3-4B Model

This repository contains the official PreSINQ GGUF-quantized versions of the Qwen3-8B model. For a detailed explanation of PreSINQ strategy please refer to the the official SINQ repository. SINQ is a fast and high-quality quantization technique designed to significantly reduce Large Language Model size while preserving accuracy.

If you find this project useful, please consider giving a ⭐ to the official SINQ repository.

Model Details

Model Name: Qwen3-8B-PreSINQ-GGUF
Base Model: Qwen/Qwen3-8B
Task: Text Generation
Framework: PyTorch / Transformers
License: Apache-2.0
Quantized By: Huawei – Computing Systems Lab

How to Obtain the PreSINQ Model

The PreSINQ Qwen3-8B models are produced using the PreSINQ GGUF script available in the official SINQ repository.

The models provided here correspond to the best-performing configurations for each quantization type.

📊 Best PreSINQ Quantization Results (Qwen3-8B)

Results below are measured on the WikiText-2 test set.

Method	Bits	Size (GB)	Perplexity ↓
Baseline (FP16)	FP16	15.26	10.1019
Baseline + Q3_K_S	3-bit	3.77	11.3619
PreSINQ + Q3_K_S	3-bit	3.77	10.6786

However, you can generate good PreSINQ models (not the best one) faster by reducing the number of configurations explored during the PreSINQ script execution.

🚀 Usage

Usage Example

You can load and run the PreSINQ GGUF models using:

🤗 Transformers
llama.cpp
Any GGUF-compatible inference framework
