Fast & Low VRAM Flux.1D [4Gb tested, checkpoint]

This is a full checkpoint with 8-bit precision (FP8) based on Flux Fusion (which gives best results for me, and also there are variations with some other models). I made the checkpoint just for my own convenience. Unet, Clips and VAE merged to the checkpoint are described in this article.

It's okay to have 4GB VRAM and 32GB RAM to use the checkpoint. Simple testing ComfyUI workflow (.json file) is attached here as "Training Data" in .zip archive. 1024x1440 image generation takes ~80 seconds on my notebook with 4GB 3050 and i5-11400.

8 steps are enough to generate hi-res sharp images.

Just download and run it.

Enjoy.
