Supports NVIDIA GPUs (vLLM, Transformers) and Apple Silicon (MLX). For more information, see https://github.com/z-lab/paroquant. z-lab/Qwen3.5-4B-PARO is a 4-bit [Qwen/Qwen3.5-4B](https://huggingface.co/Qwen/Qwen3.5-4B) quantized with ParoQuant. Check out other ParoQuant models from the Hugging Face [collection](https://huggingface.co/collections/z-lab/paroquant). ## Quick Start ### Installation ```bash # NVIDIA GPU (CUDA 12.9) pip install "paroquant[vllm]" # NVIDIA GPU (CUDA 13.0) pip install "paroquant[vllm]" "vllm==0.19.1" \ --extra-index-url https://wheels.vllm.ai/0.19.1/cu130 \ --extra-index-url https://download.pytorch.org/whl/cu130 # Apple Silicon pip install "paroquant[mlx]" ``` ### Interactive Chat ```bash python -m paroquant.cli.chat --model z-lab/Qwen3.5-4B-PARO ``` ### OpenAI-Compatible API Server For vLLM, you can directly use `vllm serve` to serve ParoQuant models: ```bash vllm serve z-lab/Qwen3.5-4B-PARO --port 8000 ``` For other frameworks: ```bash python -m paroquant.cli.serve --model z-lab/Qwen3.5-4B-PARO --port 8000 ``` For MLX, add `--vlm` if you wish to load the VLM components and use the model's multimodal features. For vLLM, VLM components are loaded by default and can be skipped with the server argument `--language-model-only`. > [!NOTE] > The visual components in this checkpoint is stored in original precision, and only the language components are quantized to 4 bits; as a result, the model size is larger than a fully-quantized model. Avoid loading the V...
