Qwen-Image 2.1 on 10 GB of VRAM
Yes, but only just: Q8_0 leaves 0.1 GB free on 10 GB. September 2026: a new 7B model that does text-to-image and editing in one, with transparent-background (RGBA) output. Far lighter than the 20B Qwen-Image.
Q8_0 (7.6 GB) fits with only 0.1 GB to spare (about 9.9 GB of 10 GB).

03The text encoder
At 9.4 GB even the smallest Qwen3-VL 8B file is too big for 10 GB, so it runs from system RAM. That slows down reading the prompt, not the picture. Sizes: 16-bit 17.5 GB, INT8 9.4 GB. Why the encoder does not count against VRAM →
