FLUX.1 Krea [dev] on 10 GB of VRAM
Not at full quality. The 16-bit and 8-bit files are too big for 10 GB; the largest that fits is Q4_K_M (6.9 GB). A FLUX.1 dev fine-tune by Krea, aimed at a more photographic, less "AI-looking" style. Same architecture and sizes as dev.
Q4_K_M (6.9 GB) fits with only 0.8 GB to spare (about 9.2 GB of 10 GB). Quality: good; some loss in fine detail and text. For better quality, Q5_K_M (8.4 GB) also runs, with about 0.7 GB spilling into system RAM - a little slower, still practical.
Also try the FP8 file (11.9 GB) on NVIDIA GPUs. It does not fit entirely, but a current ComfyUI streams the overflow from RAM and native 8-bit files often beat a small GGUF that does fit. Dynamic VRAM →
