What is it?

Fooocus is a Gradio-based image generation application that runs locally and offline. It aims to offer the ease of online services like Midjourney, so users mainly write prompts and supply images rather than tuning sampler and model settings. Installation is simplified to a few clicks, and the project lists a minimum of 4GB Nvidia VRAM and 8GB system memory.

The app covers text-to-image, image-to-image style variation, upscaling, inpainting and outpainting, image prompts with face swap, and image description. Prompt expansion is built in through a GPT-2 based engine, and styles, aspect ratios and LoRAs can be chosen from the interface. Presets such as the default, anime and realistic editions switch between different default models.

The project is now in limited long-term support with bug fixes only, and it is built on SDXL rather than newer architectures such as Flux. Windows, Linux, Mac (MPS), AMD (DirectML/ROCm beta) and CPU-only setups are documented, and Docker and Colab are also supported.

Key features

  • 01Text-to-image generation with prompt expansion and style presets
  • 02Image-to-image variation, upscaling and image prompts with face swap
  • 03Inpainting and outpainting in all four directions
  • 04Preset editions for general, anime and realistic styles
  • 05Optional HTTP listener, share link and basic authentication via auth.json
  • 06Wildcards and inline LoRA syntax in prompts

Use cases

  • Quickly producing SDXL-quality artwork without learning node-based workflows
  • Generating illustrations or photo-style images on a local GPU without cloud fees
  • Editing parts of an existing image through inpainting or extending its borders
  • Hosting a private image generation UI for a small group on a local network

Quick start

  1. 1

    Download the Windows package from the official releases link

  2. 2

    Uncompress the file and run run.bat

  3. 3

  4. 4

    Install requirements and launch with the launcher

    pip install -r requirements_versions.txt && python entry_with_update.py

Things to know

  • Minimum requirement is a 4GB Nvidia GPU and 8GB RAM, and it relies on Windows virtual swap on low-memory systems.
  • The project is in limited long-term support with bug fixes only and no plans to adopt newer model architectures like Flux.
  • AMD GPU support is in beta and not intensively tested.
  • Licensed under GPL-3.0, a copyleft license.
