AI Summary

Overview

Unlock the power of cutting-edge diffusion models with stable-diffusion.cpp, a high-performance inference engine written entirely in pure C/C++. Built upon the efficient ggml library and inspired by the success of llama.cpp, this project delivers remarkably lightweight and dependency-free diffusion model execution. Experience rapid image generation and editing across a vast array of models, optimized for diverse hardware including CPUs, GPUs (CUDA, Metal, Vulkan, OpenCL, SYCL), and even mobile platforms.

Key Features

Broad Model Support: Generate images with Stable Diffusion (v1.x, v2.x, SDXL, SD3/SD3.5), FLUX, Wan, Qwen-Image, Z-Image, Lens, Chroma, PiD, and many more. Also includes support for image editing models, video generation (Wan, LTX, MiniMax-H3), PhotoMaker, IP-Adapter, Control Net, ADetailer, LoRA, LCM/LCM-LoRA, and faster decoding with TAESD.
Cross-Platform Performance: Leverages advanced CPU instruction sets (AVX, AVX2, AVX512) and GPU acceleration across CUDA, Vulkan, Metal, OpenCL, and SYCL. Runs on Linux, macOS, Windows, and even Android.
Flexible Weight Formats: Supports standard PyTorch checkpoints (.ckpt, .pth, .pt), Safetensors (.safetensors), and the optimized GGUF format.
Lightweight & Dependency-Free: Designed for minimal resource usage and no external library dependencies, making deployment incredibly simple.
Efficient Memory Management: Features like Flash Attention, VAE tiling, and caching significantly reduce memory consumption.
Extensive Sampling Methods: Includes a comprehensive list of sampling methods like Euler A, DPM++, and LCM for fine-grained control over generation.
Reproducible Results: Offers multiple RNG backends for consistent and reproducible image generation.
Embedded Generation Data: PNG outputs can embed generation parameters in a stable-diffusion-webui-compatible format.
Active Development: Continuously updated with support for the latest models and features.

Typical Use Cases
