Open code, a licensed model

Two different licences apply when you use Image MLX Lab: one for our code, one for the model it runs. Please read both.

The code — MIT License

Copyright © 2026 Houjun Co., Ltd. The MIT License in plain words — this summary does not replace the licence:

• Use, copy, change, merge, publish, distribute and sell the code, for any purpose, free of charge — including in commercial and closed-source products.
• Keep the copyright notice and the licence text with every copy or substantial part.
• There is no warranty.

The model — Qwen Research License

Image MLX Lab does not include any model weights. During setup you download Qwen-Image-2.1 (as 4-bit or 8-bit MLX packages derived from it, and optionally its vision module) from their publishers. That model is made by Qwen and governed by the Qwen Research License Agreement:

• It allows non-commercial research and evaluation.
• Commercial use of the model — and of what you make with it, as far as its licence reaches — needs a separate licence from Qwen.
• The MIT License on our code does not and cannot give you any rights in the model.

In practice: using Image MLX Lab with its default model is for non-commercial use. If you want to use it for paid work or in a product, get a commercial licence from Qwen first, or use the code with a model whose licence allows it.

Not covered by the MIT License

• The models, as above.
• Third-party software — mlx-serve, MLX, Python packages and build tools — keeps its own licences. The repository ships only a patch for mlx-serve.
• The Image MLX Lab name and icon identify this project; the MIT License does not give permission to use them as the name or logo of another product or service.
• Demo images on this site and in the repository were generated for the project; they are there to show the software.
