Update

This has been pending for a while, but finally uploaded some massive changes

Ask for help

To avoid having this repo rely just on me, I'd love to have additional maintainers with full admin rights. If you're interested, ping me!

Additionally, I'd love area-experts for different platform to help with best practices:

• Running on AMD GPUs
• Running on CPU
• Running on Apple M1
• Running on Windows

The goal is to actually integrate all best options for uniform out-of-the-box experience without the need to tweak anything manually.

How WebUI is started is pretty much completely changed:

This should be fully cross-platform, but I would really love to have additional contibutors and/or maintainers to join and help lead the effords on different platforms

• webui.bat and webui.sh:
  Platform specific wrapper scripts that starts launch.py in Python virtual environment
  Note: Server can run without virtual environment, but it is recommended to use it
  This is carry-over from original repo
  If you're unsure which launcher to use, this is the one you want
• launch.py:
  Main startup script
  Can be used directly to start server in manually activated venv or to run it without venv
• setup.py:
  Main installer, used by launch.py
  Can also be used directly to update repository or extensions
  If running manually, make sure to activate venv first (if used)
  Setup details are logged to setup.log
• webui.py:
  Main server script

Note: by default, launcher/setup will re-check dependencies and update extensions and submodules on each startup.
This can be disabled with cmd flag --noupdate

Alternatively, you can run in quick mode if you're sure everything is up-to-date by adding cmd flag --quick

Btw, if you're wondering what takes most time during startup: its running installers for each extension - so having large number of extensions installed has a major performance impact on server startup time

Example startup sequence:

More work to be done, but all essentials are in place

Built-in performance profiler

Enable with --profile flag

Simplified dependencies and updated core libraries

Yes, requirements-versions.txt is gone

Settings changes

Quite a few defaults have been changed, but if you're have your config.json, it will remain as-is
To reset settings to defaults, delete config.json and restart server

UI changes

Until I make CSS cleaner, this is a bit ugly so I do not recommend using 3rd party themes for now

Moved almost all command line params to settings configurable from UI

This includes choices of cross-optimization and memory attention as well as configuration of system paths

See:

• Settings -> System Paths
• Settings -> Stable Diffusion

Yes, cmd flags like --xformers are gone

This is whats left:

[vladmandic]

Update for 04/27/2023:

a bit shorter list as:

1. i've been busy with buxfixing
   there are a lot of them, not going to list each here.
   but seems like critical issues backlog is quieting down and soon i can focus on new features development.
2. i've started collaboration with couple of major projects,
   hopefully this will accelerate future development.

• ability to view/add/edit model description shown in extra networks cards
• add option to specify fallback sampler if primary sampler is not compatible with desired operation
• make clip skip a local parameter
• remove obsolete items from UI settings
• set defaults for AMD ROCm
  if you have issues, you may want to start with a fresh install so configuration can be created from scratch
• set defaults for Apple M1/M2
  if you have issues, you may want to start with a fresh install so configuration can be created from scratch

[vladmandic]

Update for 05/01/2023

Been a bit quieter for last few days as changes were quite significant, but finally here we are...

• Updated core libraries: Gradio, Diffusers, Transformers
• Added support for Intel ARC GPUs via Intel OneAPI IPEX (auto-detected)
• Added support for TorchML (set by default when running on non-compatible GPU or on CPU)
• Enhanced support for AMD GPUs with ROCm
• Enhanced support for Apple M1/M2
• Redesigned command params: run webui --help for details
• Redesigned API and script processing
• Experimental support for multiple Torch compile options
• Improved sampler support
• Google Colab: https://colab.research.google.com/drive/126cDNwHfifCyUpCCQF9IHpEdiXRfHrLN
  Maintained by https://github.com/Linaqruf/sd-notebook-collection
• Fixes, fixes, fixes...

To take advantage of new out-of-the-box tunings, its recommended to delete your config.json so new defaults are applied. Its not necessary, but otherwise you may need to play with UI Settings to get the best of Intel ARC, TorchML, ROCm or Apple M1/M2.

[vladmandic]

Update for 05/04/2023

Again, few days later...

• reviewed/ported all commits from A1111 upstream
  some a few are not applicable as i already have alternative implementations
  and very few i choose not to implement (save/restore last-known-good-config is a bad hack)
  otherwise, we're fully up to date (its doesn't show on fork status as code merges were mostly manual due to conflicts)
  but...due to sheer size of the updates, this may introduce some temporary issues
• redesigned server restart function
  now available and working in ui
  actually, since server restart is now a true restart and not ui restart, it can be used much more flexibly
• faster model load
  plus support for slower devices via stream-load function (in ui settings)
• better logging
  this includes new --debug flag for more verbose logging when troubleshooting

[vladmandic]

Update for 2024-02-07

Another big release just hit the shelves!

Highlights

• A lot more functionality in the Control module:
  • Inpaint and outpaint support, flexible resizing options, optional hires
  • Built-in support for many new processors and models, all auto-downloaded on first use
  • Full support for scripts and extensions
• Complete Face module
  implements all variations of FaceID, FaceSwap and latest PhotoMaker and InstantID
• Much enhanced IPAdapter modules
• Brand new Intelligent masking, manual or automatic
  Using ML models (LAMA object removal, REMBG background removal, SAM segmentation, etc.) and with live previews
  With granular blur, erode and dilate controls
• New models and pipelines:
  Segmind SegMoE, Mixture Tiling, InstaFlow, SAG, BlipDiffusion
• Massive work integrating latest advances with OpenVINO, IPEX and ONNX Olive
• Full control over brightness, sharpness and color shifts and color grading during generate process directly in latent space
• Documentation! This was a big one, with a lot of new content and updates in the WiKi

Plus welcome additions to UI performance, usability and accessibility and flexibility of deployment as well as API improvements
And it also includes fixes for all reported issues so far

As of this release, default backend is set to diffusers as its more feature rich than original and supports many additional models (original backend does remain as fully supported)

Also, previous versions of SD.Next were tuned for balance between performance and resource usage.
With this release, focus is more on performance.
See Benchmark notes for details, but as a highlight, we are now hitting ~110-150 it/s on a standard nVidia RTX4090 in optimal scenarios!

Further details:

• For basic instructions, see README
• For more details on all new features see full CHANGELOG
• For documentation, see WiKi

Full changelog

• Heavily updated Wiki
• Control:
  • new docs:
    • Control overview
    • Control guide, thanks @Aptronymist
  • add inpaint support
    applies to both img2img and controlnet workflows
  • add outpaint support
    applies to both img2img and controlnet workflows
    note: increase denoising strength since outpainted area is blank by default
  • new mask module
    • granular blur (gaussian), erode (reduce or remove noise) and dilate (pad or expand)
    • optional live preview
    • optional auto-segmentation using ml models
      auto-segmentation can be done using segment-anything models or rembg models
      note: auto segmentation will automatically expand user-masked area to segments that include current user mask
    • optional auto-mask
      if you dont provide mask or mask is empty, you can instead use auto-mask to automatically generate mask
      this is especially useful if you want to use advanced masking on batch or video inputs and dont want to manually mask each image
      note: such auto-created mask is also subject to all other selected settings such as auto-segmentation, blur, erode and dilate
    • optional object removal using LaMA model
      remove selected objects from images with a single click
      works best when combined with auto-segmentation to remove smaller objects
    • masking can be combined with control processors in which case mask is applied before processor
    • unmasked part of can is optionally applied to final image as overlay, see settings mask_apply_overlay
  • support for many additional controlnet models
    now built-in models include 30+ SD15 models and 15+ SDXL models
  • allow resize both before and after generate operation
    this allows for workflows such as: image -> upscale or downscale -> generate -> upscale or downscale -> output
    providing more flexibility and than standard hires workflow
    note: resizing before generate can be done using standard upscalers or latent
  • implicit hires
    since hires is only used for txt2img, control reuses existing resize functionality
    any image size is used as txt2img target size
    but if resize scale is also set its used to additionally upscale image after initial txt2img and for hires pass
  • add support for scripts and extensions
    you can now combine control workflow with your favorite script or extension
    note extensions that are hard-coded for txt2img or img2img tabs may not work until they are updated
  • add depth-anything depth map processor and trained controlnet
  • add marigold depth map processor
    this is state-of-the-art depth estimation model, but its quite heavy on resources
  • add openpose xl controlnet

      Plus (150MB) uses InsightFace to generate face embeds and CLIP-ViT-H-14-laion2B (3.8GB) as image encoder
      SXDL (1022MB) uses InsightFace to generate face embeds and OpenCLIP-ViT-bigG-14 (3.7GB) as image encoder
  • FaceSwap
    • face swap performs face swapping at the end of generation
    • based on InsightFace in-swapper
  • PhotoMaker
    • for SD-XL only
    • new model from TenencentARC using similar concept as IPAdapter, but with different implementation and

Update for 2024-02-22

Only 3 weeks since last release, but here's another feature-packed one!
This time release schedule was shorter as we wanted to get some of the fixes out faster.

Highlights

• IP-Adapters & FaceID: multi-adapter and multi-image suport
• New optimization engines: DeepCache, ZLUDA and Dynamic Attention Slicing
• New built-in pipelines: Differential diffusion and Regional prompting
• Big updates to: Outpainting (noised-edge-extend), Clip-skip (interpolate with non-integrer values!), CFG end (prevent overburn on high CFG scales), Control module masking functionality
• All reported issues since the last release are addressed and included in this release

Further details:

• For basic instructions, see README
• For more details on all new features see full CHANGELOG
• For documentation, see WiKi
• Discord server

Full ChangeLog for 2024-02-22

• Improvements:
  • IP Adapter major refactor
    • support for multiple input images per each ip adapter
    • support for multiple concurrent ip adapters
      note: you cannot mix & match ip adapters that use different CLiP models, for example Base and Base ViT-G
    • add adapter start/end to settings, thanks @AI-Casanova
      having adapter start late can help with better control over composition and prompt adherence
      having adapter end early can help with overal quality and performance
    • unified interface in txt2img, img2img and control
    • enhanced xyz grid support
  • FaceID now also works with multiple input images!
  • Differential diffusion
    img2img generation where you control strength of each pixel or image area
    can be used with manually created masks or with auto-generated depth-maps
    uses general denoising strength value
    simply enable from img2img -> scripts -> differential diffusion
    note: supports sd15 and sdxl models
  • Regional prompting as a built-in solution
    usage is same as original implementation from @hako-mikan
    click on title to open docs and see examples of full syntax on how to use it
    simply enable from scripts -> regional prompting
    note: supports sd15 models only
  • DeepCache model acceleration
    it can produce massive speedups (2x-5x) with no overhead, but with some loss of quality
    settings -> compute -> model compile -> deep-cache and settings -> compute -> model compile -> cache interval
  • ZLUDA experimental support, thanks @lshqqytiger
    • ZLUDA is CUDA wrapper that can be used for GPUs without native support
    • best use case is AMD GPUs on Windows, see wiki for details
  • Outpaint control outpaint now uses new alghorithm: noised-edge-extend
    new method allows for much larger outpaint areas in a single pass, even outpaint 512->1024 works well
    note that denoise strength should be increased for larger the outpaint areas, for example outpainting 512->1024 works well with denoise 0.75
    outpaint can run in img2img mode (default) and inpaint mode where original image is masked (if inpaint masked only is selected)
  • Clip-skip reworked completely, thanks @AI-Casanova & @Disty0
    now clip-skip range is 0-12 where previously lowest value was 1 (default is still 1)
    values can also be decimal to interpolate between different layers, for example clip-skip: 1.5, thanks @AI-Casanova
  • CFG End new param to control image generation guidance, thanks @AI-Casanova
    sometimes you want strong control over composition, but you want it to stop at some point
    for example, when used with ip-adapters or controlnet, high cfg scale can overpower the guided image
  • Control

New models

While still waiting for Stable Diffusion 3.0, there have been some significant models released in the meantime:

• PixArt-Σ, high end diffusion transformer model (DiT) capable of directly generating images at 4K resolution
• SDXS, extremely fast 1-step generation consistency model
• Hyper-SD, 1-step, 2-step, 4-step and 8-step optimized models

Note
SD.Next is no longer marked as a fork of A1111 and github project has been fully detached
Given huge number of changes with +3443/-3342 commits diff (at the time of fork detach) over the past year,
a completely different backend/engine and a change of focus, it is time to give credit to original author, and move on!

Full ChangeLog for 2024-05-28

• Features:
  • ModernUI preview of the new ModernUI
  • PWA SD.Next is now installable as a web-app and includes verified manifest
  • **Gallery
  • Gallery: list, preview, search through all your images and videos!
    Implemented as infinite-scroll with client-side-caching and lazy-loading while being fully async and non-blocking
    Search or sort by path, name, size, width, height, mtime or any image metadata item, also with extended syntax like width > 1000
    Settings: optional additional user-defined folders, thumbnails in fixed or variable aspect-ratio
  • HiDiffusion:
    Generate high-resolution images using your standard models without duplicates/distorsions AND improved performance
    For example, SD15 can now go up to 2024x2048 and SDXL up to 4k natively
    Simply enable checkbox in advanced menu and set desired resolution
    Additional settings are available in settings -> inference settings -> hidiffusion
    And can also be set and used via xyz grid
    Note: HiDiffusion resolution sensitive, so if you get error, set resolution to be multiples of 128
  • Perturbed-Attention Guidance
    PAG enhances sample quality by utilizing self-attention in formation of latent in addition to standard CFG scale
    Simply set advanced -> attention guidance and advanced -> adaptive scaling
    Additional options are available in settings -> inference settings -> pag
    Note: PAG has replaced SAG as attention guidance method in SD.Next
  • LayerDiffuse
    Create transparent images with foreground-only being generated
    Simply select from scripts -> apply to current model
    All necessary files will be auto-downloaded on first use
  • IP Adapter Masking:
    Powerful method of using masking with ip-adapters
    When combined with multiple ip-adapters, it allows for different inputs guidance for each segment of the input image
    Hint: to create masks, you can use manually created masks or control->mask module with auto-segment to create masks and later upload them
  • IP Adapter advanced layer configuration:
    Allows for more control over how each layer of ip-adapter is applied, requires a valid dict to be passed as input
    See InstantStyle for details
  • OneDiff: new optimization/compile engine, thanks @aifartist
    As with all other compile engines, enable via settings -> compute settings -> compile
  • ToDo Token Downsampling for Efficient Generation of High-Resolution Images
    Newer alternative method to ToMe that can provide speed-up with minimal quality loss
    Enable in settings -> inference settings -> token merging
    Also available in XYZ grid
  • Outpaint:
    New method of outpainting that uses a combination of auto-masking and edge generation to create seamless transitions between original and generated image
    Use on control tab:
    • input -> denoising strength: 0.5 or higher
    • select image -> outpaint -> expand edges or zoom out to desired size
    • size -> mode: outpaint, method: nearest
    • mask -> inpaint masked only (if you want to keep original image)
  • Wildcards:
    • native support of standard file-based wildcards in prompt
    • enabled by default, can be disabled in settings -> extra networks if you want to use 3rd party extension
    • wildcards folder is set in settings -> system paths and can be flat-file list or complex folder structure
    • matches strings "__*__" in positive and negative prompts
    • supports filename and path-based wildcards
    • supports nested wildcards (wildcard can refer to another wildcard, etc.)
    • supports wildcards files in one-choice per line or multiple choices per line separated by | format
    • note: this is in addition to previously released style-based wildcards
• Models:
  • Load UNET: ability to override/load external UNET to a selected model
    Works similar to how VAE is selected and loaded: Set UNet folder and UNet model in settings
    Can be replaced on-the-fly, not just during initial model load
    Enables usage of fine-tunes such as DPO-SD15 or DPO-SDXL
    Note: if there is a JSON file with the same name as the model it will be used as Unet config, otherwise Unet config from currently loaded model will be used
  • PixArt-Σ
    pixart-Σ is a high end diffusion Transformer model (DiT) with a T5 encoder/decoder capable of directly generating images at 4K resolution
    to use, simply select from networks -> models -> reference -> PixArt-Σ
    note: this is a very large model at ~22GB
    set parameters: sampler: Default
  • SDXS
    sdxs is an extremely fast 1-step generation consistency model that also uses TAESD as quick VAE out-of-the-box
    to use, simply select from networks -> models -> reference -> SDXS
    set parameters: sampler: CMSI, steps: 1, cfg_scale: 0.0
  • Hyper-SD
    sd15 and sdxl 1-step, 2-step, 4-step and 8-step optimized models using lora
    set parameters: sampler: TCD or LCM, steps: 1/2/4/8, cfg_scale: 0.0
• UI:
  • Faster UI load times
  • Theme types:
    Standard (built-in themes), Modern (experimental nextgen ui), None (used for Gradio and Huggingface 3rd party themes)
    Specifying a theme type updates list of available themes
    For example, Gradio themes will not appear as available if theme type is set to Standard
  • Redesign of base txt2img interface
  • Minor tweaks to styles: refresh/apply/save
  • See details in WiKi
• API:
  • Add API endpoint /sdapi/v1/control and CLI util cli/simple-control.py
    (in addition to previously added /sdapi/v1/preprocessors and /sdapi/v1/masking)
    example:

    simple-control.py --prompt 'woman in the city' --sampler UniPC --steps 20
    --input ~/generative/Samples/cutie-512.png --output /tmp/test.png --processed /tmp/proc.png
    --control 'Canny:Canny FP16:0.7, OpenPose:OpenPose FP16:0.8' --type controlnet
    --ipadapter 'Plus:~/generative/Samples/cutie-512.png:0.5'

  • Add API endpoint /sdapi/v1/vqa and CLI util cli/simple-vqa.py
• Changes:
  • Due to change in Diffusers model loading
    initial model load will now fetch config files required for the model
    from the Huggingface site instead of using predefined YAML files
  • Removed built-in extensions: ControlNet and Image-Browser
    as both image-browser and controlnet have native built-in equivalents
    both can still be installed by user if desired
  • Different defaults depending on available GPU, thanks @Disty0
    • 4GB and below: lowvram
    • 8GB and below: medvram
    • Cross-attention: Dynamic Attention SDP with medvram or lowvram, otherwise SDP
    • VAE Tiling enabled with medvram and lowvram
    • Disable Extract EMA by default
    • Disable forced VAE Slicing for lowvram
  • Upscaler compile disabled by default with OpenVINO backend
  • Hypernetwork support disabled by default, can be enabled in settings
• Improvements:
  • Faster server startup
  • Styles apply wildcards to params
  • Face HiRes fully configurable and higher quality when using high-resolution models
  • Extra networks persistent sort order in settings
  • Add option to make batch generations use fully random seed vs sequential
  • Make metadata in full screen viewer optional
  • Add VAE civitai scan metadata/preview
  • More efficient in-browser callbacks
  • Updated all system requirements

  • UI styles includes indicator for active styles
  • UI reduce load on browser
  • Secondary sampler add option "same as primary"
  • Change attention mechanism on-the-fly without model reload, thanks @Disty0
  • Update stable-fast with support for torch 2.2.2 and 2.3.0, thanks @Aptronymist
  • Add torch cudaMallocAsync in compute options
    Can improve memory utilization on compatible GPUs (RTX and newer)
  • Torch dynamic profiling
    You can enable/disable full torch profiling in settings top menu on-the-fly
  • Prompt caching - if you use the same prompt multiple times, no need to re-parse and encode it
    Useful for batches as prompt processing is ~0.1sec on each pass
  • Enhance SD_PROMPT_DEBUG to show actual tokens used
  • Support controlnet manually downloads models in both standalone and diffusers format
    For standalone, simply copy safetensors file to models/control/controlnet folder
    For diffusers format, create folder with model name in models/control/controlnet/
    and copy model.json and diffusion_pytorch_model.safetensors to that folder
• Samplers
  • Add Euler SGM variation (e.g. SGM Uniform), optimized for SDXL-Lightning models
    note: you can use other samplers as well with SDXL-Lightning models
  • Add CMSI sampler, optimized for consistency models
  • Add option timestep spacing to sampler settings and sampler section in main ui
    Note: changing timestep spacing changes behavior of sampler and can help to make any sampler turbo/lightning compatibile
  • Add option timesteps to manually set timesteps instead of relying on steps+spacing
    Additionally, presets from nVidias align-you-steps reasearch are provided
    Result is that perfectly aligned steps can drastically reduce number of steps needed!
    For example, AYS preset alows DPM++2M to run in ~10 steps with quality equallying ~30 steps!
• IPEX, thanks @Disty0
  • Update to IPEX 2.1.20 on Linux
    requires removing the venv folder to update properly
  • Removed 1024x1024 workaround
  • Disable ipexrun by default, set IPEXRUN=True if you want to use ipexrun

Update for 08/31/2024

Summer break is over and we are back with a massive update!

Support for all of the new models:

• Black Forest Labs FLUX.1
• AuraFlow 0.3
• AlphaVLLM Lumina-Next-SFT
• Kwai Kolors
• HunyuanDiT 1.2

What else? Just a bit... ;)

New fast-install mode, new Optimum Quanto and BitsAndBytes based quantization modes, new balanced offload mode that dynamically offloads GPU<->CPU as needed, and more...
And from previous service-pack: new ControlNet-Union all-in-one model, support for DoRA networks, additional VLM models, new AuraSR upscaler

Breaking Changes...

Due to internal changes, you'll need to reset your attention and offload settings!
But...For a good reason, new balanced offload is magic when it comes to memory utilization while sacrificing minimal performance!

Details

New Models...

To use and of the new models, simply select model from Networks -> Reference and it will be auto-downloaded on first use

• Black Forest Labs FLUX.1
  FLUX.1 models are based on a hybrid architecture of multimodal and parallel diffusion transformer blocks, scaled to 12B parameters and builing on flow matching
  This is a very large model at ~32GB in size, its recommended to use a) offloading, b) quantization
  For more information on variations, requirements, options, and how to donwload and use FLUX.1, see Wiki
  SD.Next supports:
  • FLUX.1 Dev and FLUX.1 Schnell original variations
  • additional qint8 and qint4 quantized variations
  • additional nf4 quantized variation
• AuraFlow
  AuraFlow v0.3 is the fully open-sourced largest flow-based text-to-image generation model
  This is a very large model at 6.8B params and nearly 31GB in size, smaller variants are expected in the future
  Use scheduler: Default or Euler FlowMatch or Heun FlowMatch
• AlphaVLLM Lumina-Next-SFT
  Lumina-Next-SFT is a Next-DiT model containing 2B parameters, enhanced through high-quality supervised fine-tuning (SFT)
  This model uses T5 XXL variation of text encoder (previous version of Lumina used Gemma 2B as text encoder)
  Use scheduler: Default or Euler FlowMatch or Heun FlowMatch
• Kwai Kolors
  Kolors is a large-scale text-to-image generation model based on latent diffusion
  This is an SDXL style model that replaces standard CLiP-L and CLiP-G text encoders with a massive chatglm3-6b encoder supporting both English and Chinese prompting

  support for additional models: SD 1.5 v3 (Sparse), SD Lightning (4-step), SDXL Beta

New Features...

• support for Balanced Offload, thanks @Disty0!
  balanced offload will dynamically split and offload models from the GPU based on the max configured GPU and CPU memory size
  model parts that dont fit in the GPU will be dynamically sliced and offloaded to the CPU
  see Settings -> Diffusers Settings -> Max GPU memory and Max CPU memory
  note: recommended value for max GPU memory is ~80% of your total GPU memory
  note: balanced offload will force loading LoRA with Diffusers method
  note: balanced offload is not compatible with Optimum Quanto
• support for Optimum Quanto with 8 bit and 4 bit quantization options, thanks @Disty0 and @Trojaner!
  to use, go to Settings -> Compute Settings and enable "Quantize Model weights with Optimum Quanto" option

For more details see: Changelog | ReadMe | Wiki | Discord

Details

Major refactor of FLUX.1 support:

• allow configuration of individual FLUX.1 model components: transformer, text-encoder, vae
  model load will load selected components first and then initialize model using pre-loaded components
  components that were not pre-loaded will be downloaded and initialized as needed
  as usual, components can also be loaded after initial model load
  note: use of transformer/unet is recommended as those are flux.1 finetunes
  note: manually selecting vae and text-encoder is not recommended
  note: mix-and-match of different quantizations for different components can lead to unexpected errors
  • transformer/unet is list of manually downloaded safetensors
  • vae is list of manually downloaded safetensors
  • text-encoder is list of predefined and manually downloaded text-encoders
• controlnet support:
  support for InstantX/Shakker-Labs models including Union-Pro
  note that flux controlnet models are large, up to 6.6GB on top of already large base model!
  as such, you may need to use offloading:sequential which is not as fast, but uses far less memory
  when using union model, you must also select control mode in the control unit
  flux does not yet support img2img so to use controlnet, you need to set contronet input via control unit override
• model support loading all-in-one safetensors
  not recommended due to massive duplication of components, but added due to popular demand
  each such model is 20-32GB in size vs ~11GB for typical unet fine-tune
• improve logging, warn when attempting to load unet as base model
• refiner support
  FLUX.1 can be used as refiner for other models such as sd/sdxl
  simply load sd/sdxl model as base and flux model as refiner and use as usual refiner workflow
• img2img, inpaint and outpaint support
  note flux may require higher denoising strength than typical sd/sdxl models
  note: img2img is not yet supported with controlnet
• transformer/unet support fp8/fp4 quantization
  this brings supported quants to: nf4/fp8/fp4/qint8/qint4
• vae support fp16
• lora support additional training tools
• face-hires support
• support fuse-qkv projections
  can speed up generate
  enable via settings -> compute -> fused projections

Other improvements & Fixes:

• CogVideoX
  • support for both 2B and 5B variations
  • support for both text2video and video2video modes
  • simply select in scripts -> cogvideox
  • as with any video modules, includes additional frame interpolation using RIFE
  • if init video is used, it will be automatically resized and interpolated to desired number of frames
• AnimateDiff:
  • prompt travel
    create video which travels between different prompts at different steps!
    example prompt:

    0: dog
    5: cat
    10: bird

  • support for v3 model (finally)
  • support for LCM model
  • support for free-noise rolling context window
    allow for creation of much longer videos, automatically enabled if frames > 16
• Context-aware image resize, thanks @AI-Casanova!
  based on seam-carving
  allows for img2img/inpaint even at massively different aspect ratios without distortions!
  simply select as resize method when using img2img or control tabs
• HDR high-dynamic-range image create for SD and SDXL
  create hdr images from in multiple exposures by latent-space modifications during generation
  use via scripts -> hdr
  option save hdr images creates images in standard 8bit/channel (hdr-effect) and 16bit/channel (full-hdr) PNG format
  ui result is always 8bit/channel hdr-effect image plus grid of original images used to create hdr
  grid image can be disabled via settings -> user interface -> show grid
  actual full-hdr image is not displayed in ui, only optionally saved to disk
• new scheduler: DC Solver
• color grading apply professional color grading to your images
  using industry-standard .cube LUTs!
  enable via scripts -> color-grading
• hires workflow now allows for full resize options
  not just limited width/height/scale
• xyz grid is now availabe as both local and global script!
• prompt enhance: improve quality and/or verbosity of your prompts
  simply select in scripts -> prompt enhance
  uses gokaygokay/Flux-Prompt-Enhance model
• taesd configurable number of layers
  can be used to speed-up taesd decoding by reducing number of ops
  e.g. if generating 1024px image, reducing layers by 1 will result in preview being 512px
  set via settings -> live preview -> taesd decode layers
• xhinker prompt parser handle offloaded models
• control better handle offloading
• upscale will use resize-to if set to non-zero values over resize-by
  applies to any upscale options, including refine workflow
• networks add option to choose if mouse-over on network should attempt to fetch additional info
  option:extra_networks_fetch enable/disable in settings -> networks
• speed up some garbage collection ops
• sampler settings add dynamic shift
  used by flow-matching samplers to adjust between structure and details
• sampler settings force base shift
  improves quality of the flow-matching samplers
• t5 support manually downloaded models
  applies to all models that use t5 transformer

  • MiaoshouAI PromptGen 1.5 Base
  • MiaoshouAI PromptGen 1.5 Large
  • CogFlorence 2.2 Large
• modernui update
• zluda update to 3.8.4, thanks @lshqqytiger!

README | CHANGELOG | WiKi | Discord

Details for 2024-10-23

• reprocess

  • new top-level button: reprocess latent from your history of generated image(s)
  • generate using full-quality:off and then reprocess using full quality decode
  • generate without hires/refine and then reprocess with hires/refine
    note: you can change hires/refine settings and run-reprocess again!
  • reprocess using detailer

• history

  • by default, reprocess will pick last latent, but you can select any latent from history!
  • history is under networks -> history
    each history item includes info on operations that were used, timestamp and metadata
  • any latent operation during workflow automatically adds one or more items to history
    e.g. generate base + upscale + hires + detailer
  • history size: settings -> execution -> latent history size
    memory usage is ~130kb of ram for 1mp image
  • note list of latents in history is not auto-refreshed, use refresh button

• model analyzer

  • see all details of your currently loaded model, including components, parameter count, layer count, etc.
  • in models -> current -> analyze

• text encoder:

  • allow loading different custom text encoders: clip-vit-l, clip-vit-g, t5
    will automatically find appropriate encoder in the loaded model and replace it with loaded text encoder
    download text encoders into folder set in settings -> system paths -> text encoders
    default models/Text-encoder folder is used if no custom path is set
    finetuned clip-vit-l models: Detailed, Smooth, LongCLIP
    reference clip-vit-l and clip-vit-g models: OpenCLIP-Laion2b
    note sd/sdxl contain heavily distilled versions of reference models, so switching to reference model produces vastly different results
  • xyz grid support for text encoder
  • full prompt parser now correctly works with different prompts in batch

• detailer:

  • replaced face-hires with detailer which can run any number of standard detailing models
  • includes face/hand/person/eyes predefined detailer models plus support for manually downloaded models
    set path in settings -> system paths -> yolo
  • select one or more models in detailer menu and thats it!
  • to avoid duplication of ui elements, detailer will use following values from refiner:
    sampler, steps, prompts
  • when using multiple detailers and prompt is multi-line, each line is applied to corresponding detailer
  • adjustable settings:
    strength, max detected objects, edge padding, edge blur, min detection confidence, max detection overlap, min and max size of detected object
  • image metadata includes info on used detailer models
  • note detailer defaults are not save in ui settings, they are saved in server settings
    to apply your defaults, set ui values and apply via system -> settings -> apply settings
  • if using models trained on multiple classes, you can specify which classes you want to detail
    e.g. original yolo detection model is trained on coco dataset with 80 predefined classes
    if you leave field blank, it will use any class found in the model
    you can see classes defined in the model while model itself is loaded for the first time

• extract lora: extract combined lora from current memory state, thanks @AI-Casanova
  load any LoRA(s) and play with generate as usual and once you like the results simply extract combined LoRA for future use!
  in models -> extract lora

• sampler options: full rewrite

  sampler notes:

  • pick a sampler and then pick values, all values have "default" as a choice to make it simpler
  • a lot of options are new, some are old but moved around
    e.g. karras checkbox is replaced with a choice of different sigma methods
  • not every combination of settings is valid
  • some settings are specific to model types
    e.g. sd15/sdxl typically use epsilon prediction
  • quite a few well-known schedulers are just variations of settings, for example:
    • sampler sgm is sampler with trailing spacing and sample prediction type
    • dpm 2m or 3m are dpm 1s with orders of 2 or 3
    • dpm 2m sde is dpm 2m with sde as solver
    • sampler simple is sampler with trailing spacing and linear beta schedule
  • xyz grid support for sampler options
  • metadata updates for sampler options
  • modernui updates for sampler options
  • note sampler options defaults are not save in ui settings, they are saved in server settings
    to apply your defaults, set ui values and apply via system -> settings -> apply settings

  sampler options:

  • sigma method: karas, beta, exponential
  • timesteps spacing: linspace, leading, trailing
  • beta schedule: linear, scaled, cosine
  • prediction type: epsilon, sample, v-prediction
  • timesteps presents: none, ays-sd15, ays-sdxl
  • timesteps override:
  • sampler order: 0=default, 1-5
  • options: dynamic, low order, rescale

• Ctrl+X:

  • control structure (similar to controlnet) and appearance (similar to ipadapter)
    without the need for extra models, all via code feed-forwards!
  • can run in structure-only or appearance-only or both modes
  • when providing structure and appearance input images, its best to provide a short prompts describing them
  • structure image can be almost anything: actual photo, openpose-style stick man, 3d render, sketch, depth-map, etc.
    just describe what it is in a structure prompt so it can be de-structured and correctly applied
  • supports sdxl in both txt2img and img2img, simply select from scripts

• APG: Adaptive Projected Guidance

  • latest algo to provide better guidance for image generation, can be used instead of existing guidance rescale and/or PAG
  • in addtion to stronger guidance and reduction of burn at high guidance values, it can also increase image details
  • compatible with sd15/sdxl/sc
  • select in scripts -> apg
  • for low cfg scale, use positive momentum: e.g. cfg=2 => momentum=0.6
  • for normal cfg scale, use negative momentum: e.g. cfg=6 => momentum=-0.3
  • for high cfg scale, use neutral momentum: e.g. cfg=10 => momentum=0.0

• LinFusion

  • apply liner distillation to during load to any sd15/sdxl model
  • can reduce vram use for high resolutions and increase performance
  • note: use lower cfg scales as typical for distilled models

• Flux

  • support for both kohya and onetrainer loras in native load mode for fp16/nf4/fp4, thanks @AI-Casanova
  • support for differential diffusion
  • added native load mode for qint8/qint4 models
  • avoid unet load if unchanged

• OmniGen

  • Radical new model with pure LLM architecture based on Phi-3
  • Select from networks -> models -> reference
  • Can be used for text-to-image and image-to-image
  • Image-to-image is very different, you need to specify in prompt what do you want to do
    and add |image| placeholder where input image is used!
    examples: in |image| remove glasses from face, using depth map from |image|, create new image of a cute robot
  • Params used: prompt, steps, guidance scale for prompt guidance, refine guidance scale for image guidance
    Recommended: guidance=3.0, refine-guidance=1.6

• Stable Diffusion 3.5 Large

  • New/improved variant of Stable Diffusion 3
  • Select from networks -> models -> reference
  • Available in standard and turbo variations
  • Note: Access to to both variations of SD3.5 model is gated, you must accept the conditions and use HF login

• CogView 3 Plus

  • Select from networks -> models -> reference
  • resolution width and height can be from 512px to 2048px and must be divisible by 32
  • precision: bf16 or fp32
    fp16 is not supported due to internal model overflows

• Meissonic

  • Select from networks -> models -> reference
  • Experimental as upstream implemenation code is unstable
  • Must set scheduler:default, generator:unset

• SageAttention

  • new 8-bit attention implementation on top of SDP that can provide acceleration for some models, thanks @Disty0
  • enable in settings -> compute settings -> sdp options -> sage attention
  • compatible with DiT-based models: e.g. Flux.1, AuraFlow, CogVideoX
  • not compatible with UNet-based models, e.g. SD15, SDXL

• gpu

  • previously cuda_dtype in settings defaulted to fp16 if available
  • now cuda_type defaults to Auto which executes bf16 and fp16 tests on startup and selects best available dtype
    if you have specific requirements, you can still set to fp32/fp16/bf16 as desired
    if you have gpu that incorrectly identifies bf16 or fp16 availablity, let us know so we can improve the auto-detection
  • support for torch expandable segments
    enable in settings -> compute -> torch expandable segments
    can provide significant memory savings for some models
    not enabled by default as its only supported on latest versions of torch and some gpus

• xyz grid full refactor

  • multi-mode: selectable-script and alwayson-script
  • allow usage combined with other scripts
  • allow unet selection
  • allow passing model args directly:
    allowed params will be checked against models call signature
    example: width=768; height=512, width=512; height=768
  • allow passing processing args directly:
    params are set directly on main processing object and can be known or new params
    example: steps=10, steps=20; test=unknown
  • enable working with different resolutions
    now you can adjust width/height in the grid just as any other param
  • renamed options to include section name and adjusted cost of each option
  • added additional metadata

• interrogate

  • add additional blip models: blip-base, blip-large, blip-t5-xl, blip-t5-xxl, opt-2.7b, opt-6.7b
  • change default params for better memory utilization
  • lock commits for miaoshouAI-promptgen
  • add optional advanced params
  • update logging

• lora auto-apply tags to prompt

  • controlled via settings -> networks -> lora_apply_tags
    0:disable, -1:all-tags, n:top-n-tags
  • uses tags from both model embedded data and civitai downloaded data
  • if lora contains no tags, lora name itself will be used as a tag
  • if prompt contains _tags_ it will be used as placeholder for replacement, otherwise tags will be appended
  • used tags are also logged and registered in image metadata
  • loras are no longer filtered per detected type vs loaded model type as its unreliable
  • loras display in networks now shows possible version in top-left corner
  • correct using of extra_networks_default_multiplier if not scale is specified
  • improve lora base model detection
  • improve lora error handling and logging
  • setting lora_load_gpu to load LoRA directly to GPU
    default: true unless lovwram

• quantization

  • new top level settings group as we have quite a few quantization options now!
    configure in settings -> quantization
  • in addition to existing optimum.quanto and nncf, we now have bitsandbytes and torchao
  • bitsandbytes: fp8, fp4, nf4
    • quantization can be applied on-the-fly during model load
    • currently supports transformers and t5 in sd3 and flux
  • torchao: int8, int4, fp8, fp4, fpx
    • configure in settings -> quantization
    • can be applied to any model on-the-fly during load

• huggingface:

  • force logout/login on token change
  • unified handling of cache folder: set via HF_HUB or HF_HUB_CACHE or via settings -> system paths

• cogvideox:

  • add support for image2video (in addition to previous text2video and video2video)
  • note: image2video requires separate 5b model variant

• torch

  • due to numerous issues with torch 2.5.0 which was just released as stable, we are sticking with 2.4.1 for now

• backend=original is now marked as in maintenance-only mode

• python 3.12 improved compatibility, automatically handle setuptools

• control

  • persist/reapply units current state on server restart
  • better handle size before/after metadata

• video add option gradio_skip_video to avoid gradio issues with displaying generated videos
