A pure C/C++ inference engine for diffusion models (Stable Diffusion, FLUX, Wan, Qwen Image, Z-Image, and more) built on ggml in the style of llama.cpp. It ships as a lightweight dependency-free library plus CLI with text-to-image, image-to-image, image editing, and video generation support.

Use cases

• generate images from text prompts without python
• run stable diffusion inference in pure C++
• run FLUX or Qwen Image models locally on CPU or GPU
• embed diffusion model inference into a C++ application
• convert text to image from the command line
• run image editing models like FLUX Kontext locally
• generate videos with Wan or LTX models

When to choose

• you need lightweight, dependency-free diffusion inference in C/C++
• you want llama.cpp-style local inference without Python or PyTorch
• you need to embed image generation into a native application
• you want broad model support including SD, SDXL, SD3, FLUX, and Wan

When to avoid

• you need the full Python ecosystem of diffusers pipelines and extensions
• you want a polished GUI-first image generation tool
• you need a frozen, stable API - the project is under active development and interfaces change frequently
