Qwen-Image on 32 GB of VRAM
Yes. Q8_0 fits on 32 GB with 7.4 GB to spare. Alibaba's 20B text-to-image model, known for rendering long text and posters well. Big: the 8-bit file alone is over 20 GB.
Q8_0 (21.8 GB) needs about 24.6 GB in use, so 7.4 GB of the 32 GB stays free: room for a larger image, a LoRA or a ControlNet.
Got an RTX 40 or 50? Swap Q8_0 for FP8 (20.4 GB): same quality class, computed natively there.
