Stable Diffusion 1.5 on 10 GB of VRAM
Yes. 16-bit fits on 10 GB with 6.7 GB to spare. The 2022 model that started it all. Under 1B parameters, native 512 px, and still a huge library of fine-tunes. Runs on almost anything.
Runs well
Yes, with room to spare.
16-bit (2.1 GB) needs about 3.3 GB in use, so 6.7 GB of the 10 GB stays free: room for a larger image, a LoRA or a ControlNet.
