Download the Flux models
----> Step 1 Download Latest version of Flux NF4 12gb (recommended): https://huggingface.co/lllyasviel/flux1-dev-bnb-nf4/tree/main
----> Step 2 Put inside /Forge/webui/models/Stable-diffusion/
----> Step 3 Run Update.bat
----> Step 4 Start your Forge - Select FLUX and FLUX model.
Generate!
NF4 or FP8?
NF4 is significantly faster than other versions of Flux, like the FP8. I recommend using the NF4 model for faster speeds and lower VRAM requirements. It will run on 6gb+ vram machines.
The "regular" Flux models will give you somewhat better quality (at least for FP16) at a substantially longer generation time.
Optional model download: Flux FP8 17gb: https://huggingface.co/lllyasviel/flux1_dev/blob/main/flux1-dev-fp8.safetensors

From lllyasviel github:
"If your device supports CUDA newer than 11.7 then you can use NF4. (Most RTX 3XXX/4XXX GPUs supports this.) Congratulations. Enjoy the speed. In this case, you only need to download the flux1-dev-bnb-nf4.safetensors.
If your device is GPU with GTX 10XX/20XX then your device may not support NF4, please download the flux1-dev-fp8.safetensors."
