Features

Image Generation

• Stable Diffusion 2.1 support.
• txt2img.
• img2img.
• Inpainting.
• 14 Samplers: ddim, plms, heun, euler, euler_a, dpm2, dpm2_a, lms, dpm_solver_stability, dpmpp_2s_a, dpmpp_2m, dpmpp_sde, dpm_fast, dpm_adaptive.

Image Filters

• GFPGAN for face restoration.
• RealESRGAN (and anime) for upscaling.

Models

• Models DB to allow downloading known models with a single line of code.
• Models DB allows automatic detection of the config file to use (e.g. for SD 2.1 and 2.0 "v" type models).
• Fast loading/unloading of VAE models, without needing to reload the entire Stable Diffusion model.
• Custom models for Stable Diffusion in .ckpt or .safetensors format.
• Custom models for VAE in .ckpt or .safetensors format.
• Custom models for Hypernetworks in .pt or .safetensors format.
• API to merge two models (in .ckpt or .safetensors format).

Performance & Security

• VRAM Optimizations to allow generating 512x512 images on GPUs with less than 4gb of VRAM.
• "Balanced" optimizations to achieve high rendering speed with fairly low VRAM usage.
• Support for .safetensors file format, for secure model loading.
• Automatic scanning of Stable Diffusion models before loading them (picklescan).
• Support for running on multiple GPUs in parallel.
