🎨 ComfyUI Workflows & Custom LoRAs

A curated collection of production-grade ComfyUI workflows paired with custom-trained LoRAs across multiple state-of-the-art diffusion architectures (SDXL, FLUX, Klein, and Z-Image Turbo).

Due to file size limits on GitHub, all heavy model weights (.safetensors) are hosted for free on Hugging Face, while execution workflows (.json) and installation guides are stored directly in this repository.

📁 Repository & Directory Layout

To keep your local ComfyUI setup organized, models and workflows are categorized into dedicated subfolders by architecture:

├── workflows/
│   ├── sdxl/               # SDXL ComfyUI workflow JSONs
│   ├── flux/               # FLUX ComfyUI workflow JSONs
│   └── z_image_turbo/      # Z-Image Turbo ComfyUI workflow JSONs
└── README.md

Additional notes- the loras are all different weights and rank, some may output better quality on certain prompts. For sdxl loras, recommended checkpoints are wai illustrative, anythingxl and meinamix [but it works with almost all sdxl checkpoints, try it out :)]

⚡ How to Use

[TRIGGER WORD SAME AS MODEL NAME]

1. Download Model Weights- https://huggingface.co/stomp001/free-character-models/tree/main

1. Visit the Hugging Face repository linked above.
2. Download the .safetensors files for the architectures you wish to use.
3. Place them into your local ComfyUI setup under ComfyUI/models/loras/ (you can keep them organized in subfolders like loras/sdxl/, loras/flux/, etc.).

2. Load Workflows

1. Open your local ComfyUI.
2. Navigate to the workflows/ folder in this repository.
3. Drag and drop any .json workflow file directly onto your ComfyUI canvas workspace.
4. Ensure your Load LoRA nodes are pointed to the correct subfolder path for the model you downloaded.
5. Click Queue Prompt to generate!

🛠️ Recommended Custom Nodes

To ensure all included workflows run smoothly without missing node errors, make sure you have the following custom nodes installed via ComfyUI Manager:

• ComfyUI-Manager (To resolve missing nodes automatically)
• ComfyUI-Quick-Merge (For automated batching and image layering)
