Note

Styles wildcards are separate feature that standard wildcards which can also be used in parallel

Styles can be selected via Networks interface -> Styles
or via shortcut combo-box control below generate buttons

There can be any number of styles selected and each style will be applied in order they are selected.

Each style is a separate JSON file that can be edited manually or via UI. Location of styles is specified in Settings -> System Paths -> Styles folder, default is models\styles

Tip

Button ↶ "Apply selected style to prompt" will apply currently selected styles to current prompt as-is and remove style from being applied during runtime

Tip

Button ↷ "Save current prompt to style" will simply save current prompt to named style. Such style can be later edited for more fine-tuning

Migration

Old A1111 style concept was a flat file in CSV format and SD.Next supports migration of such styles to new JSON format
Simply put a full path to the CSV file in Settings -> System Paths -> Styles and restart server at which point
server will migrate found styles into individual JSON files.

Prompt

Prompt specified in style will be either used to replace a placeholder {prompt} in the current prompt or if there is no placeholder, it will be appeneded at the end of the current prompt

Example:

"national geographic style photo shot on sony a7 camera"

Parameters

In addition to prompt, you can also specify any generation parameters in the style
List of parameters is comma-separated and each parameter is a key-value pair indicated by colon :

Note

Recognized parameters are all parameters that can be typically found in image metadata,
but they can also include and of the generation parameters and any of the server settings!

Example:

Model: PrometheusV1, Size: 1152x864, Sampler: DPM++ 2M SDE, CFG scale: 5, Steps: 30, Seed: 3849770518, Refine: True, Hires: True, Refiner steps: 20, hr_upscaler: ESRGAN 4x NMKD Siax, hr_scale: 1.5, hr_denoising_strength: 0.3, save_to_dirs: True

Wildcards

Both prompt and parameters can be modified using wildcards section inside the style
List of wildcards is comma-separated and each wildcard is a key-value pair indicated by =
Multiple wildcards can be listed and separated by semi-colon ;

Example#1:

Prompt: "a woman wearing a {color} dress"
Wildcard: "{color}=red, green, blue"

Example#2:

Prompt: "{style} a woman wearing a {color} dress"
Wildcard: "{style}=photo, sketch, painting; {color}=red, green, blue"

Example#3:

Parameters: "Size: {size}"
Wildcard: "{size}=1024x1024, 1024x768, 768x1024, 1280x720, 720x1280, 1536x640"

JSON

Structure of the style is a simple JSON object:

{
  "name": "Cute Robot",
  "description": "This is a style of a random cute robot",
  "prompt": "photo of a cute {color} robot, walking {where} with {background} visible in background",
  "negative": "",
  "extra": "Size: {size}",
  "wildcards": "
    {color}=blue, red, rusty, silver, cyan;
    {where}=on alien planet, in rainforest, in the city street;
    {background}=rocks and mountains, moon and planets, spaceship, battle;
    {size}=1024x1024, 1280x720, 720x1280"
}

Validation

Styles use will be logged in the standard log with debug level:

DEBUG Applying style: name="mine/Cute Robot" extra=[] skipped=[] reference=False
DEBUG Wildcards applied: {'{color}': 'red', '{what}': 'water', '{background}': 'moon and planets'} path="/mnt/models/wildcards" type=style time=0.00
