💡 Philosophy

MFLUX is a line-by-line MLX port of several state-of-the-art generative image models from the Huggingface Diffusers and Huggingface Transformers libraries. All models are implemented from scratch in MLX, using only tokenizers from the Huggingface Transformers library. MFLUX is purposefully kept minimal and explicit, @karpathy style.

💿 Installation

If you haven't already, install uv, then run:

uv tool install --upgrade mflux

After installation, the following command shows all available MFLUX CLI commands:

uv tool list 

To generate your first image using, for example, the z-image-turbo model, run

mflux-generate-z-image-turbo \
  --prompt "A puffin standing on a cliff" \
  --width 1280 \
  --height 500 \
  --seed 42 \
  --steps 9 \
  -q 8

The first time you run this, the model will automatically download which can take some time. See the model section for the different options and features, and the common README for shared CLI patterns and examples.

#!/usr/bin/env -S uv run --script
# /// script
# requires-python = ">=3.10"
# dependencies = [
#   "mflux",
# ]
# ///
from mflux.models.z_image import ZImageTurbo

model = ZImageTurbo(quantize=8)
image = model.generate_image(
    prompt="A puffin standing on a cliff",
    seed=42,
    num_inference_steps=9,
    width=1280,
    height=500,
)
image.save("puffin.png")

uv run generate.py

uv tool install --upgrade mflux --with hf_transfer

uv tool install --python 3.13 mflux

🎨 Models

MFLUX supports the following model families. They have different strengths and weaknesses; see each model’s README for full usage details.

✨ Features

General

• Quantization and local model loading
• LoRA support (multi-LoRA, scales, library lookup), including LyCORIS LoKr on FLUX.1 and FLUX.2
• Metadata export + reuse, plus prompt file support

Model-specific highlights

• Text-to-image and image-to-image generation.
• LoRA finetuning
• In-context editing, multi-image editing, and virtual try-on
• ControlNet (Canny), depth conditioning, fill/inpainting, and Redux
• Upscaling (SeedVR2 and Flux ControlNet)
• Depth map extraction and FIBO prompt tooling (VLM inspire/refine)

See the common README for detailed usage and examples, and use the model section above to browse specific models and capabilities.

[!NOTE] As MFLUX supports a wide variety of CLI tools and options, the easiest way to navigate the CLI in 2026 is to use a coding agent (like Cursor, Claude Code, or similar). Ask questions like: “Can you help me generate an image using z-image?”

Build a UI under mflux.web

We welcome independently distributed mflux.web.* implementations using Gradio, FastAPI, FastHTML, or any other UI framework. Each project can choose its own framework, dependencies, release schedule, and launch command.

mflux owns the parent initializer and inference implementation. Its package path extends across installed distributions, including separate editable checkouts. mflux.web is an implicit namespace package: Python combines the mflux/web/ directories contributed by independently installed UI packages. No intermediate distribution is required; neither core nor UI packages need to depend on mflux-web. The mflux-web distribution reserves the generic mflux-web name on PyPI; it does not provide the shared namespace and does not need to be installed. Its optional demo is just another child module, mflux.web.demo.

Your UI distribution owns a unique child, for example src/mflux/web/example_ui/__init__.py. With uv_build, configure module-name = "mflux.web.example_ui". Declare mflux and your chosen framework as dependencies with versions your UI supports. The minimum mflux version for split-directory installs must include this parent path extension.

Do not ship mflux/__init__.py, which belongs to core, or mflux/web/__init__.py, which must remain absent for the implicit namespace. Choose a unique child name to avoid collisions. PyPI distribution names can use hyphens; Python child names must be valid identifiers, such as example_ui. Reserving a PyPI distribution name does not reserve a Python namespace.

After installation in the same environment, consumers can use import mflux.web.example_ui. Installing a UI does not automatically launch it, discover applications, or mount routes. UI framework dependencies belong to the individual UI distributions; this namespace support adds none to mflux.
