๐ ๏ธ Flux Kontext Manual Download Guide
🕑 Added 2025-07-27 16:36:28 +0000 UTCThis guide walks you through the manual setup for the Flux Kontext workflow. For the best experience, right-click any file link and choose "Save Link As..." into the specified folder.
โก Want the easy route?
Just use the one-click installer. It sets everything up automatically (models, nodes, dependencies).
This manual guide is only here in case you're on unsupported hardware or want full control.
โ If you're using ComfyUI Desktop, you're fully supported.
๐ฆ Custom Nodes
Open a terminal inside the custom_nodes/ folder and run:
git clone https://github.com/Maxed-Out-99/ComfyUI-MaxedOut.git
git clone https://github.com/Maxed-Out-99/ComfyUI-SmartModelLoaders-MXD.git
This installs the custom nodes.
๐ง Install Node Requirements
Now activate your virtual environment to install Python dependencies.
Windows:
.venv\Scripts\activate
Mac:
.venv/bin/activate
Then install the node requirements:
python -m pip install -r custom_nodes/ComfyUI-SmartModelLoaders-MXD/requirements.txt
Thatโs it. โ
๐พ Core Files
๐พ Right-click any file link โ choose "Save Link As..." โ Save into the specified folder inside ComfyUI/models/
ae.safetensors โก๏ธ vae/
clip_l.safetensors โก๏ธ clip/
โ ๏ธ You can optionally download a quantized Nunchaku model for faster performance on NVIDIA GPUs only:
RTX 50 series: svdq-fp4_r32-flux.1-kontext-dev.safetensors โก๏ธ diffusion_models/
All other NVIDIA GPUs: svdq-int4_r32-flux.1-kontext-dev.safetensors โก๏ธ diffusion_models/
๐ CLIP & T5 Models
Select ONE T5 model based on your system's RAM (not VRAM) and place into models/clip/.
Tier A (32GB):
Tier B (16 GB):
Tier C (Less than 16 GB):
๐ง UNet Models
Choose one UNet model based on your GPU VRAM. Save into models/diffusion_models/.
๐ถ Tier S (32GB VRAM): FP16
๐ถ Tier A (16GB - 31GB VRAM): FP8
๐ถ Tier B (12GB - 15GB VRAM): Good Quality (GGUF Q5)
๐ถ Tier C (Less than 12GB VRAM / Apple Silicon / CPU): VRAM Optimized (GGUF Q3)
โ Done!
Once you've:
Downloaded your models,
Selected one UNet + one T5 tier,
Placed everything into the correct folders,
Installed my nodes and their requirements,
You're ready to run the Flux Kontext workflow manually ๐
Enjoy! And if you're stuck, you can always fall back to the one-click installer.
