# Stable Diffusion web UI (AUTOMATIC1111)

> The original popular Stable Diffusion web UI: text-to-image, img2img, inpainting, outpainting, several upscalers (RealESRGAN, ESRGAN, SwinIR, LDSR) and a large extension ecosystem. Code is AGPL-3.0. If no model is present it downloads Stable Diffusion 1.5 (CreativeML OpenRAIL-M). Activity is low: last master commit 2024-07-27, latest release v1.10.1 on 2025-02-09, last dev-branch push 2026-03-02. It wants Python 3.10.6 on Windows and supports 4GB GPUs.

## What it replaces
- Midjourney: Text-to-image, Image editing (inpainting and outpainting), Upscaling (partial). Generation, inpainting/outpainting and upscaling with SD-family models; no built-in style reference; slow development.
- Adobe Firefly: Text-to-image, Image editing (generative fill and expand) (partial). Text-to-image plus inpainting and outpainting with SD-family models.
