What's new?

v2.5

Major Changes

• Nearly twice as fast - significantly faster speed of image generation. We're now pretty close to automatic1111's speed. Code contributions are welcome to make our project even faster: https://github.com/easydiffusion/sdkit/#is-it-fast
• Mac M1/M2 support - Experimental support for Mac M1/M2. Thanks @michaelgallacher, @JeLuf and vishae.
• Full support for Stable Diffusion 2.1 (including CPU) - supports loading v1.4 or v2.0 or v2.1 models seamlessly. No need to enable "Test SD2", and no need to add sd2_ to your SD 2.0 model file names. Works on CPU as well.
• Memory optimized Stable Diffusion 2.1 - you can now use Stable Diffusion 2.1 models, with the same low VRAM optimizations that we've always had for SD 1.4. Please note, the SD 2.0 and 2.1 models require more GPU and System RAM, as compared to the SD 1.4 and 1.5 models.
• 11 new samplers! - explore the new samplers, some of which can generate great images in less than 10 inference steps! We've added the Karras and UniPC samplers. Thanks @Schorny for the UniPC samplers.
• Model Merging - You can now merge two models (.ckpt or .safetensors) and output .ckpt or .safetensors models, optionally in fp16 precision. Details: https://github.com/cmdr2/stable-diffusion-ui/wiki/Model-Merging . Thanks @JeLuf.
• Fast loading/unloading of VAEs - No longer needs to reload the entire Stable Diffusion model, each time you change the VAE
• Database of known models - automatically picks the right configuration for known models. E.g. we automatically detect and apply "v" parameterization (required for some SD 2.0 models), and "fp32" attention precision (required for some SD 2.1 models).
• Color correction for img2img - an option to preserve the color profile (histogram) of the initial image. This is especially useful if you're getting red-tinted images after inpainting/masking.
• Three GPU Memory Usage Settings - High (fastest, maximum VRAM usage), Balanced (default - almost as fast, significantly lower VRAM usage), Low (slowest, very low VRAM usage). The Low setting is applied automatically for GPUs with less than 4 GB of VRAM.
• Find models in sub-folders - This allows you to organize your models into sub-folders inside models/stable-diffusion, instead of keeping them all in a single folder. Thanks @patriceac and @ogmaresca.
• Custom Modifier Categories - Ability to create custom modifiers with thumbnails, and custom categories (and hierarchy of categories). Details: https://github.com/cmdr2/stable-diffusion-ui/wiki/Custom-Modifiers . Thanks @ogmaresca.
• Embed metadata, or save as TXT/JSON - You can now embed the metadata directly into the images, or save them as text or json files (choose in the Settings tab). Thanks @patriceac.
• Major rewrite of the code - Most of the codebase has been reorganized and rewritten, to make it more manageable and easier for new developers to contribute features. We've separated our core engine into a new project called sdkit, which allows anyone to easily integrate Stable Diffusion (and related modules like GFPGAN etc) into their programming projects (via a simple pip install sdkit): https://github.com/easydiffusion/sdkit/
• Name change - Last, and probably the least, the UI is now called "Easy Diffusion". It indicates the focus of this project - an easy way for people to play with Stable Diffusion.

Our focus continues to remain on an easy installation experience, and an easy user-interface. While still remaining pretty powerful, in terms of features and speed.

• 2.5.16 - 10 Feb 2023 - The "Make Images" button now shows the correct amount of images it'll create when using operators like {} or |. For e.g. if the prompt is Photo of a {woman, man}, then the button will say Make 2 Images. Thanks @JeLuf.
