Node Details

latent > RandomImageSizeAdvancedYAML

Generates an empty latent and supports fixed or random resolution selection. Presets are loaded from yaml/model_resolutions.yaml and can be temporarily extended or overridden at runtime.

Key features

YAML-based resolution presets per model key.
Random selection from a preset group or from all presets.
width_override and height_override take highest precedence.
add_random_resolutions extends the random pool.
override_random_resolutions replaces the random pool.
Resolutions accept NUMBERxNUMBER entries separated by commas, semicolons, or spaces.
Width/height are rounded down to multiples of 64 unless overrides are provided.
The final resolutions are pushed into str_result_1x_resolution and str_result_nx_resolution in the UI.
If the YAML file changes between machines, the node attempts to re-sync its widget options.

Inputs (main)

batch_size: Latent batch size.
random_pick_state: None, All, or a YAML key.
image_size: Used when random_pick_state is None.
width_override / height_override: Force final resolution.
resolution_multiplier: Scale factor used for nx_width/nx_height and str_result_nx_resolution.

Outputs

LATENT, width, height, NX_LATENT, nx_width, nx_height, resolution_multiplier, str_result_1x_resolution, str_result_nx_resolution.

latent > RandomImageSizeAdvanced

Same behavior as RandomImageSizeAdvancedYAML, but uses hardcoded resolution lists inside py/random_image_size.py (SDXL/Qwen/Flux/Flux2 presets).

number > CyclicInteger

Selects an integer based on a mode:

fixed: Keep the incoming value.
increment: Wrap around within [min_value, max_value].
decrement: Wrap around within [min_value, max_value].
randomize: Random integer within [min_value, max_value].

Outputs the integer and a string version of it. Also updates the integer widget in the UI.

number > RandomInteger

When random_on_off is true, picks a random integer in [min, max]. Otherwise passes through the input integer. Outputs the integer and a string version of it, and updates the integer widget in the UI.

string > UniqueStringList

Splits a comma-separated string and separates unique and duplicate items. Items containing BREAK are always treated as unique. Whitespace-only items are preserved in the unique output.

Outputs

unique_text: Comma-joined unique items.
duplicate_text: Comma-joined duplicates.

string > UniqueStringListAdvanced

Splits a comma-separated string into unique and duplicate lists with normalization options.

Key behavior

remove_whitespaces: Collapses whitespace and removes empty tokens.
remove_underscore: Treats _ as spaces for comparison/output.
Items containing uppercase BREAK are always treated as unique.
Duplicate detection uses normalized keys, while duplicate output keeps the raw tokens.

Outputs

unique_text: Joined unique items (, when whitespace removal is enabled, otherwise ,).
duplicate_text: Joined duplicates (, delimiter).

string > Output Dir By Model Name

Builds output_dir, file_name, and full_path from a model name, optional prefixes, and a timestamp. Values are pushed to the UI widgets via the web event listener.

Key inputs

model_name: Model name or path string.
folder_prefix, extra_filename, extra_number: Optional components.
use_first_dir, use_ckpt_name, use_time_folder, use_time_file_name: Toggle output parts.

Outputs

str_model_name: Echo of the model name.
full_path, output_dir, file_name.

loader > Checkpoint Loader Advanced

Loads a checkpoint with optional clip layer override and optional external VAE, plus the same output path generation used by Output Dir By Model Name.

Key inputs

ckpt_name: Checkpoint selection.
vae_name: Baked VAE or a specific VAE file.
stop_at_clip_layer: 0 uses the default clip, otherwise applies clip skip.
enable_make_path and path toggles: Same behavior as Output Dir By Model Name.

Outputs

MODEL, CLIP, VAE, ckpt_name.
full_path, output_dir, file_name.

parameter > BFParameters

Parameter pack that outputs base, upscaling (ups_*), and secondary (dt_*) sampling values plus string versions of sampler/scheduler names for logging or UI use.

parameter > BFParametersSimple

Compact parameter pack that outputs seed, steps, cfg, sampler/scheduler, detailer scheduler, and two denoise values with string versions of sampler/scheduler names.

parameter > Checkpoint Arg / Unet Arg / VAE Arg / Ksampler Sampler Arg / Ksampler Scheduler Arg / Detailer Scheduler Arg

Lightweight passthrough nodes that expose common UI combos and also output string versions for logging or routing.

Customizing model_resolutions.yaml

Edit yaml/model_resolutions.yaml to define your own resolution presets.

Example:

SDXL:
  - "1024x1024"
  - "1152x896"
  - "896x1152"

Custom:
  - "800x1200"
  - "1200x800"

Web Extension

This pack ships web/js/event-listener.js to sync widget values for certain nodes (resolution strings and output paths). ComfyUI loads the web directory automatically when the custom node is installed.
