Updated UI for FunPack Apply LoRA Weights. Now it's a one-line rgthree-like styled loader which takes up significantly less space in the workflow and looks more pleasent.

Updated rating for FunPack Video Refiner. Now it uses a rating system more understandable to end user:

Rating Perfect - resulting video is an exact match or really close to what was requested;
Rating Missing details - concept and quality are present, but some prompt details/actions were omitted;
Rating Missing concept - visually pleasant, but characters or subjects are not doing what was requested;
Rating Missing quality - concept and details are attempted, but anatomy/style/scene quality is messy;
Pair ratings such as Missing details + concept, Missing details + quality, and Missing concept + quality - boost the named missing axes together;
Rating Awful - details, concept, and quality are all missing.
Rating -Just forget it- - in case of failing sampling or any other result when you are unable to see the video to rate it, select this rating so the previous generation won't count in learning process.

Updated logic for FunPack Video Refiner. The original conditioning is still stored for prompt/conditioning change detection, but after the first Perfect rating the active refinement reference switches to the liked generated conditioning. Later perfect results update that reference as a running average, while Awful can roll back to the latest better-rated conditioning before boosting all missing axes.

Dev Branch

The dev branch is intended for testing unfinished changes, implementing new logic and basically, flipping everything just because I can. It can be broken, renamed, or changed without warning.

Use only main if you want the most stable version of this node pack. Bug reports based on dev version will be ignored.

Installation

FunPack is available on Comfy Registry and can be installed in any of these ways:

With comfy-cli: comfy node install ComfyUI-FunPack
With git, inside your ComfyUI/custom_nodes directory: git clone https://github.com/digital-garbage/ComfyUI-FunPack
With ComfyUI-Manager: Open Custom Nodes Manager, search for ComfyUI-FunPack, and click Install.

Dependencies

FunPack includes a requirements.txt file for its Python dependencies.

Install them with:

pip install -r requirements.txt

FunPack uses your existing ComfyUI/PyTorch install. The expected baseline is transformers >= 5.0.0

hpsv3 is optional and only used by the FunPack StoryMem Keyframe Extractor quality filter, so it is not installed by default.

Install it manually only if you need that feature:

pip3 install hpsv3 --no-build-isolation

Important Note About `hpsv3`

Installing hpsv3 can break Prompt Enhancer and Story Writer, because hpsv3 depends on a transformers version that conflicts with the version those LLM-based nodes require.

FunPack's LLM nodes require transformers >= 5.0. The version required for hpsv3 is strictly transformers==4.45.2. Installing any version different from it will result in broken quality detector.

If you install hpsv3, use --no-build-isolation. Optionally, specify the exact version - pip install transformers==4.45.2 --no-build-isolation.

Documentation

Per-node documentation is available in the docs folder.

Start with:

docs/FunPackGemmaEmbeddingRefiner.md for FunPack Video Refiner
docs/FunPackSaveRefinementLatent.md for latent references
docs/FunPackLoraWorkflow.md for the LoRA/refiner helper workflow

Version history is available in CHANGELOG.md.

Feedback

If you have suggestions, questions, or ideas for new nodes, feel free to open an issue or submit a pull request.

Thank you

I want to say thanks to teams behind OpenAI (ChatGPT/Codex), xAI (Grok), DeepSeek, Anthropic (Claude) and Google (Gemini) for all the help with coding and transforming my ideas into something working in real UI. Thanks to all the testers and users who regularly use FunPack in their workflows, request features and report bugs. Without all of you, this project would've been just wet dreams of a wannabe coder begging on Discord for someone to add nodes he wants. Seriously, you are cool. I love you all. <3
