Save Image Organized

The default ComfyUI Save Image node works great until you've generated 2,000 test renders and they're all 00001.png through 02000.png in one folder. That's the exact complaint that keeps showing up in r/comfyui threads: people love the graph, hate the output folder. Save Image Organized (node class SaveImageClean) is the fix - a drop-in replacement that names your folders and files based on the model that actually made the image.

It's from the small comfyui-save-image-organized pack (just two nodes, no other dependencies worth fearing). The whole idea: instead of output/2026-08-16_00001.png, you get portraits/FLUX.2 Klein 9B [5K-M]/Lockout Qwen3 4B [Q8]/2026-08-16_15-30-10.png. Searchable folders, searchable filenames, and the workflow metadata you're used to still rides along inside the PNG.

How it figures out the model name

The clever part is detection. When the workflow runs, the node walks the graph upstream from its own images input to find the nearest checkpoint, UNET, or CLIP/text-encoder loader, then reads the model filename off that loader's widget. So %MODEL_NAME% becomes whatever UNETLoader (or CheckpointLoader/CLIPLoader) was feeding your sampler. If more than one loader is visible, it picks the nearest one by default - and if you run a base-pass-then-refine pipeline, you can make it prefer the first-applied loader instead. There's no AI guessing here: it's reading your actual workflow. One current limitation to know: it resolves to one model name and one text encoder name ("Primary only"), no combined multi-loader names.

If no supported loader sits upstream - say your save node is on a postprocessing-only branch with no sampler before it - detection fails gracefully and the node falls back to your Custom Model Name/Custom Text Encoder Name (the model_folder and clip_folder inputs).

The inputs that matter

You'll mostly touch four things:

• Save Layout (path_template) - the whole path in one string, defaulting to %TOP_FOLDER%/%MODEL_NAME%/%TEXT_ENCODER_NAME%/%FILENAME%%BATCH%. Clear it and you get the built-in folder order.
• Filename (filename_datetime) - defaults to %date:yyyy-MM-dd_hh-mm-ss%, so no two files collide by the second.
• If File Exists (collision_mode) - increment is the safe default. overwrite and error will bite you if a batch saves more than one image without %BATCH% in the layout (the node actually warns you about this).
• Export Workflow Metadata - on by default, matching stock ComfyUI Save Image. Turn it off for clean PNGs without embedded prompt/workflow data.

Then model_source and clip_source pick how names render: Friendly (readable, with [Q8]-style tags), Exact (the raw filename), or Custom. Optional subfolder adds a top-level folder. The template system is deeper than it looks - %node.widget% placeholders like %KSampler.seed%, %SEED%, %WIDTH%, date tokens, and :lower/:upper/:slug filters. Set Detection Info to Summary or Verbose and the node's text output tells you exactly which model and text encoder it picked, and from which loader. You can also switch the output format away from PNG if you don't need lossless saves - just know the workflow metadata only embeds in PNGs.

Install

It's a light pack - only numpy and Pillow, no model downloads, nothing that can drag your whole environment into dependency hell:

comfy node install save-image-organized

or the manual route:

cd ComfyUI/custom_nodes
git clone https://github.com/Delcado19/comfyui-save-image-organized
pip install -r comfyui-save-image-organized/requirements.txt

Restart ComfyUI and the node appears as "Save Image Organized" under image/save.

Common gotchas

• Names show as model / text-encoder - no supported upstream loader was found on that branch. Postprocessing-only saves, switch nodes bypassing the loader path, or a custom loader with an unusual widget shape all cause this. Set custom names as the fallback.
• The preview says "Last Detection Snapshot" - it's showing values from the last run after you edited the layout. Queue the workflow once more to refresh.
• Browser still shows old behavior after updating - hard-refresh; the frontend JS gets cached.
• Every image in a batch lands on the same filename - your custom layout dropped %BATCH%. Add it or switch to increment.

If you generate a lot and want to actually find your renders later, this is the one. It's not flashy - it's the node that quietly saves you from sorting 2,000 numbered PNGs.
