Warning: This is the 16-step model.

Civit doesn't support it natively, hence this workaround]A merge of Flux.D with the 16-step HyperSD LoRA from ByteDance - turned into GGUF. As a result, you get an ultra-memory efficient and fast DEV (CFG sensitive) model that generates fully denoised images with just 16 steps while consuming ~6.2 GB VRAM (for the Q4_0 quant). Also, the quality is pretty close to the original DEV model with ~30 steps.<h3 id="advantages-474uu2bkd">Advantages</h3><ul><li>Quality similar to the original DEV model, while requiring only ~16 steps.</li><li>Better quality and expressivity than the 8-step HyperFlux in general.</li><li>For the same seed, the output image is pretty similar to the original DEV model, so you can use it to do quick searches and do a final generation with the dev model.</li><li>Sometimes you might even get better results than the DEV model due to serendipity :) .</li><li>Disadvantage: requires 16 steps.</li></ul><h3 id="which-model-should-i-download-8gqt4pgur">Which model should I download?</h3>[Current situation: Using the updated Forge UI and Comfy UI (GGUF node) I can run Q8_0 on my 11GB 1080ti.]Download the one that fits in your VRAM. The additional inference cost is quite small if the model fits in the GPU.
