MLX-VLM : A Comprehensive Tool For Vision Language Models On Mac

MLX-VLM is an advanced tool designed for inference and fine-tuning of Vision Language Models (VLMs) on macOS, leveraging Apple’s MLX framework.

It enables seamless integration of vision and language tasks, offering robust support for image and video processing alongside text-based outputs.

Key Features

  1. Installation:
    MLX-VLM can be installed using pip with a single command:
   pip install mlx-vlm
  1. Usage Options:
  • Command Line Interface (CLI):
    Users can generate outputs directly from the terminal. For example:
    python -m mlx_vlm.generate --model mlx-community/Qwen2-VL-2B-Instruct-4bit --max-tokens 100 --image <image_url>
  • Chat UI with Gradio:
    A user-friendly chat interface can be launched for interactive tasks:
    python -m mlx_vlm.chat_ui --model mlx-community/Qwen2-VL-2B-Instruct-4bit
  • Python Scripting:
    Developers can integrate MLX-VLM into Python scripts for customized workflows, as shown in the example below:
    python from mlx_vlm import load, generate model, processor = load("mlx-community/Qwen2-VL-2B-Instruct-4bit") output = generate(model, processor, "Describe this image.", ["<image_url>"]) print(output)
  1. Multi-Image Chat Support:
    The tool supports multi-image analysis with models like Qwen2-VL and Pixtral, enabling complex visual reasoning across multiple images.
  2. Video Understanding:
    Select models allow video captioning and summarization, expanding its multimodal capabilities.
  3. Fine-Tuning:
    MLX-VLM supports fine-tuning via LoRA and QLoRA techniques, making it highly adaptable for specific use cases without requiring extensive computational resources.

MLX-VLM is compatible with various state-of-the-art models, including:

  • Image Models: Qwen2-VL, Phi3-Vision.
  • Video Models: Qwen2.5-VL, Idefics3.

The tool is ideal for tasks such as:

  • Image captioning and comparison.
  • Multi-modal chat involving text, images, and videos.
  • Fine-tuning VLMs locally on Apple Silicon Macs.

MLX-VLM exemplifies the growing ecosystem of tools optimized for macOS users seeking efficient machine learning solutions without relying on cloud services.
