🛠️ 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.
⚡ 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.
✅ If you're using ComfyUI Desktop, you're fully supported.
📦 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.
🔧 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
That’s it. ✅
💾 Core Files
💾 Right-click any file link → choose "Save Link As..." → Save into the specified folder inside ComfyUI/models/
ae.safetensors ➡️ vae/
clip_l.safetensors ➡️ clip/
⚠️ 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 ➡️ diffusion_models/
All other NVIDIA GPUs: svdq-int4_r32-flux.1-kontext-dev.safetensors ➡️ diffusion_models/
📎 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):
🧠 UNet Models
Choose one UNet model based on your GPU VRAM. Save into models/diffusion_models/.
🔶 Tier S (32GB VRAM): FP16
🔶 Tier A (16GB - 31GB VRAM): FP8
🔶 Tier B (12GB - 15GB VRAM): Good Quality (GGUF Q5)
🔶 Tier C (Less than 12GB VRAM / Apple Silicon / CPU): VRAM Optimized (GGUF Q3)
✅ 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 🎉
Enjoy! And if you're stuck, you can always fall back to the one-click installer.
