Qwen3-0.6b-gguf

Open4bits / Qwen3 0.6B GGUF

This repository provides GGUF-format quantized builds of the Qwen3 0.6B model, published by Open4bits for efficient local inference using llama.cpp-compatible runtimes.

The underlying Qwen3 model architecture and weights are owned by the original model authors. This repository contains only converted and quantized GGUF files and does not include training code or datasets.

These builds are intended for fast, low-memory inference on CPUs and GPUs across a wide range of hardware.

Model Overview

Qwen3 0.6B is a small-scale transformer language model designed for lightweight text generation tasks.
The GGUF format enables efficient execution in environments such as llama.cpp, llama-cpp-python, and compatible frontends.

This repository includes multiple quantization variants to balance quality, speed, and memory usage.

Intended Use

These GGUF builds are intended for:

• Local text generation
• CPU or low-VRAM GPU inference
• Embedded and edge deployments
• Research, experimentation, and prototyping

---

Usage

Example usage with llama-cpp-python:

from llama_cpp import Llama

llm = Llama(
    model_path="qwen3-0.6b-Q4_K_M.gguf",
    n_ctx=2048
)

output = llm("Write a short explanation of quantization.")
print(output["choices"][0]["text"])

---

Limitations

• Output quality is limited by the small model size
• Lower-bit quantizations may reduce accuracy
• Not instruction-tuned unless combined with external prompting strategies
