Sampler preset changes
There was quite a bit of confusion about the changes to samplers in the last release, and a few bugs too. This release will hopefully improve the situation!
The preset name now contains both:
- a descriptive part (default, fast, realtime, ...) which indicates what it might be good for and how it differs from other choices, especially for users who are not familiar with Stable Diffusion
- the technical implementation name of the sampler (Euler A, DPM++ 2M, DPM++ SDE, ...) which you may see mentioned when downloading custom checkpoints
There are two new entries:
- Alternative - Euler Ancestral with normal scheduler and step count
- Lightning Merge - Euler Ancestral with uniform scheduler and low CFG/steps
Related changes:
- "Special" Lora (LCM, Lightning, FaceID) are no longer filtered out, but a warning will be displayed if they are added manually #640
- These are added automatically when needed, eg. when choosing a sampler or control layer that requires them
- Improved error messages for samplers which require a Lora
- Don't auto-convert previous sampler settings to a preset that requires a Lora
- Fixed sampler preset choice not being persisted in some cases #649
- Custom preset link will now open the folder if the preset file cannot be opened
- Added link to format documentation in the custom preset JSON
Please check out the documentation on the Wiki for more information about Samplers and how to customize them!

Style Transfer
There are two new Control layer modes: Style and Composition.
They work similar to the "Reference" mode: the selected image acts as a sort of inspiration, and doesn't have to match resolution or aspect ratio of your canvas. The difference is that Style will extract mostly art style and colors, while Composition focuses on the structural layout.
| Composition | Style | Result |
|---|---|---|

Works best with SDXL. Probably need a different approach for SD1.5.
Important
If you are using a custom ComfyUI installation, make sure to update. Latest version of ComfyUI_IPAdapter_plus is required.
LoRA Search and Auto-Completion
Redesigned the LoRA selection into a searchable drop-down.
There is also an option to filter via folders (applies to all added LoRA).
And adding LoRA in the text prompt will auto-complete now.
Control Presets
This release adds Presets for some Control layer and Sampler settings. The idea is to have a lean, easy to use UI where users can switch between a few recommended configuration options. Presets can be customized for those who want full control (but it may require editing a text file).
Control layer strength is now adjusted with a single slider, from low influence to very strong effect. This will influence the weight as well as the start and end of the interval in which ControlNet or IP-Adapter are applied.
If you want you can also modify those individually. The presets are stored in presets/control.json, it is recommended to copy it to the user data folder before editing.
Sampler Presets
Samplers can now be fully configured by choosing from a few pre-defined options.
As before, the number of steps and guidance strength can be tweaked in the UI. New: you can edit the presets or add your own, and choose from any sampler / scheduler which ComfyUI supports.
Other Changes
- Added option to enable Self-Attention Guidance (advanced checkpoint settings) (by @FeepingCreature)
- This may improve image quality at the cost of some performance
- Fixed LoRA in the text prompt not being stored to history #586
- Fixed error when restoring settings to default values

- If you are using a custom ComfyUI installation, please update to latest versions!
Per-pixel Strength Masks
This release slightly changes how selections masks are interpreted.
Previously they would be either 1 (selected) or 0 (not selected), with smooth transitions at the edges for blending.
Now you can create masks with any values in between to customize how much the image changes per pixel.
| Original | Mask | Result |
|---|---|---|
 |
 |
 |
"spooky dense forest"
For example, if you paint a selection mask 50% white in a certain region, and set strength to 80%, the actual strength in that region will be half of 80% = 40%. This is also known as "Differential Diffusion" or "Soft Inpainting". You can allow more drastic changes in some regions and only small adjustments in others - with smooth transitions - in one generation.
| Original | Mask | Result |
|---|---|---|
 |
 |

"toxic waste, acid lake"
Hint: enable global selection masks in Krita to easily edit selection masks.
Streamlined Cloud GPU
I've been working on a streamlined online service for those who don't want to install or lack the hardware. It is not complete, but can be tested already. Please look for more information and leave your feedback in this discussion!
Note: Local offline will always be the option with the greatest flexibility. But it's not available to everyone, and sometimes convenient can be nice?
Sponsors
This project is happily eating all of my time, and it feels like it is only getting hungrier! 😵
So I've had to think about sustainability. Cloud GPU is part of that, but it's an experiment and won't appeal to everyone. If you like the project, please consider donating via GitHub ♥. Much appreciated!

Discard Images from History
For those images we'd prefer to have never happened. You can multi-select with Ctrl/Shift!
New location for User Data
User files such as settings, custom styles and logs are no longer inside the plugin installation directory. This has some advantages:
- Easier to do a clean update/reinstall of the plugin without losing your settings
- Allows system-wide plugin installation with per-user settings
The settings are now located in a subfolder of Krita's user data. Typical paths:
- Windows:
C:\User\<your-name>\AppData\Roaming\krita\ai_diffusion - Linux:
~/.local/share/krita/ai_diffusion - MacOS:
~/Library/Application Support/krita/ai_diffusion
Depending on your system the location may be different. You can find it via the "View Logs" link in the settings.

Selection Fill & Expand for Stable Diffusion XL
While SD XL has been supported for a long time, its capabilities to seamlessly fill selections were very limited. SD 1.5 almost always had superior results. This release adds the inpaint model developed by Fooocus to dramatically improve results. All SD XL checkpoints, including custom downloads, automatically profit from the change.
The new model will be downloaded as part of the "Stable Diffusion XL" workload, make sure to select it in the installer if you want to make use of it!
New Inpaint Modes
This release introduces more nuanced actions for filling and expanding areas of the image.
This nudges generation into a certain direction depending on what you want to do. Works especially well for SD XL, but also improves consitency for SD 1.5. Some examples are below, you can read the full documentation here.
| Selection | Result | |
|---|---|---|
| Fill |  |
 |
| Expand |  |

| Add Content |  |

| Remove Content |  |

Version 1.13.0
Download krita_ai_diffusion-1.13.0.zip
Important
This release includes an upgrade for ComfyUI and custom nodes.
- If you are using the managed server, the installer will do an upgrade.
- If you are using a custom ComfyUI installation, please update to latest versions!
Face Reference
You can now provide a reference image of a face and generate images with close likeness.
Generate entirely new images with flexibility to change style, lighting, etc:
Hint: Use a portrait as reference which includes hair and shoulders. Size of the reference image doesn't have to match your canvas, it's okay to leave transparent areas.
It also works for changing faces in existing images:
Installation:
- Managed server: Choose the IP-Adapter Face option from Control Extension packages. Available for both SD 1.5 and SD XL.
- Custom ComfyUI: See IP-Adapter-FaceID for models and follow the FaceID section of ComfyUI_IPAdapter_plus. I'm testing with FaceID Plus v2 models, but others may work. Installation of insightface is required.
Hand Refiner
Stable Diffusion often struggles with generating hands. Manually sketching hand posture can often be the most reliable solution.
This release adds the Hand control layer as an alternative. It automatically detects hands in the image or selected area and
tries to generate a plausible depth map. This can then be used to guide generation.
Hints and limitations:
- Works for photos and realistic shading. Fails to detect hands in flat-shaded cartoon artwork.
- You can use selections to detect specific hands!
- Refining hands requires sufficient resolution to work with.
- High strength leads to plastic look and color shifts, try around 50%.
- Hands can still be frustrating...
Installation:
- Managed server: Choose ControlNet Hand Refiner from Control Extensions packages.
- Custom ComfyUI: See HandRefiner for model and latest comfyui_controlnet_aux for preprocessor.
Live Animation Painting (experimental)
There is a new record button in the Live tab which imports results as animation. Maybe it's useful?
LiveRecordingL.mp4
High resolution version on YouTube
Other Changes
- Added option to save the last ComfyUI prompt for debug and experimentation purposes (Interface > Dump Workflow)
- Reduced default max pixel count for "high" performance profile
- Fixed wrong clip-skip setting applied to SDXL checkpoints (Styles > Checkpoint configuration (advanced) > Clip Skip) #323
- Existing custom styles are not automatically modified, you may want to revise them
- Line art control layer is no longer excluded from generation image input
- The lines themselves will become part of your image - if you don't want this hide the layer
- Fixed wrong image size when height is not a multiple of 8 but width is #306
- Fixed some UI update issues (initial upscale model, canvas change)
- Reorganized model search paths and put them all in one place #304
- Disabled IP-Adapter for AMD/DirectML (it appears to be broken) #335
- Tweaked thumbnail spacing in relation to UI font size #278
Version 1.12.0
Download krita_ai_diffusion-1.12.0.zip
Important
This release introduces new upscale models (Omni-SR):
- If you are using the managed server, the installer will download the new models
- If you are using a custom ComfyUI installation, download them here and place them in
models/upscale_models
Persistence
The following information will now be stored in .kra documents:
- Current workspace, prompt, strength, etc.
- Current control layer setup
- History of generated results
How much of the history is stored can be configured in performance settings. Keep in mind that increasing the limit also makes saving and opening documents slower! The history is compressed, so the default values are actually enough for a lot of images.
Queue Popup Menu
The queue button menu has been extended:
- Batches is like hitting the "Generate" button multiple times (but slightly faster)
- Seed options have been moved here (previously were in settings)
- Cancel buttons to manage the job queue can still be found here
Preview Context Menu
Previews thumbnails now have a context menu button. Alternatively you can always open the menu with right-click. Here you can:
- Copy generation parameters, such as prompt, strength and seed
- This will directly place them in the UI and overwrite the previous setup.
- Quickly save the generated result to disk
- It will be stored as WEBP in the same location as your document.
Resolution Performance Options
Hardware limitations are still a big problem, especially when working on a high-resolution canvas. This release provides some more options to avoid running into out-of-memory situations:
- Resolution Multiplier will scale down the resolution which images are generated at relative to the canvas resolution.
- For example, setting it to
0.5will generate images at half the resolution - To fit into your image, results are automatically upscaled with a fast AI upscaler
- For example, setting it to
- Maximum Pixel Count allows you to set a resolution limit.
- It works similar to the multiplier, but only kicks in when you cross a certain threshold
- This is enabled by default now! The limit depends on your GPU.
Checkpoint Resolution Override
Stable Diffusion checkpoints have a "preferred" resolution, and the plugin will automatically take it into account. For most checkpoints this is detected automatically and nothing has to be changed!
In some cases a checkpoint may be trained with a different resolution than its base model suggests - for cases where this cannot be detected you can now set it manually. See the example below for the recommended way to setup SDXL Turbo.
Other Changes
- Disabled area conditioning when a control layer is active - this could lead to bad inpaint results when using text prompt & control layers
- Styles are now sorted alphabetically
- History: create new section when negative prompt changes
- History: add strength value and create new section when it changes
- History: disable item dragging (by @vtvrv)
- Fixed result thumbnails not scaling with Windows display scaling #278
- Fixed crash when setting the upscale factor to a non-0.5 increment #264
- Fixed division by zero when all "Image" control layer (IP-adapter) weights are 0 #271
- Fixed history UI not being updated when old images are pruned
- Crop control layer images before sending them to the server
