#### Available Pattern Codes
##### Cross-Node Placeholders (ComfyUI Standard)
- `%NodeTitle.WidgetName%` - Reference any widget value from any node in your workflow, for example:
- `%KSampler.seed%` - The seed from a KSampler node
- `%Empty Latent Image.width%` - The width from an Empty Latent Image node
- `%KSampler.steps%` - The steps value from a KSampler node
- Nodes are matched by their "Node name for S&R" property, then by their title
##### Generation Metadata Placeholders (LoRA Manager)
- `%seed%` - Inserts the generation seed number
- `%width%` - Inserts the image width
- `%height%` - Inserts the image height
- `%pprompt:N%` - Inserts the positive prompt (limited to N characters)
- `%nprompt:N%` - Inserts the negative prompt (limited to N characters)
- `%model:N%` - Inserts the model/checkpoint name (limited to N characters)
##### Date/Time Placeholders
- `%date%` - Inserts current date/time as "yyyyMMddhhmmss"
- `%date:FORMAT%` - Inserts date using custom format with:
- `yyyy` - 4-digit year

You can combine multiple patterns to create detailed, organized filenames for your generated images.
You can combine multiple patterns to create detailed, organized filenames for your generated images. Cross-node and metadata placeholders can be mixed freely — for example: `%KSampler.seed%_%model%_%date:yyyyMMdd%`.
##### Organizing Images into Subdirectories
Including a path separator (`/` on all platforms) in the filename prefix creates subdirectories automatically, which is especially powerful when combined with placeholders:
| Pattern | Result |
|---|---|
| `%date:yyyy-MM-dd%/%seed%` | Saves to `2025-04-28/1234567890.png` |
| `%model%/%date:yyMMdd%_%seed%` | Saves to `dreamshaper_v8/250428_1234567890.png` |
| `%KSampler.seed%/%model%` | Saves to `1234567890/dreamshaper_v8.png` |
| `%date:yyyy/MM/dd%/%seed%` | Saves to `2025/04/28/1234567890.png` (nested year/month/day) |
| `%model%/training/%seed%` | Saves to `dreamshaper_v8/training/1234567890.png` |
> **Note**: The subdirectory is created relative to your ComfyUI output directory (configurable via `--output-directory`). Characters invalid for folder names are automatically replaced with underscores.
