SDXL 1.0 on 16 GB of VRAM
Yes. 16-bit fits on 16 GB with 8.9 GB to spare. The 2023 classic. One 6.9 GB checkpoint with the text encoders and VAE inside, and the biggest library of LoRAs and fine-tunes.
16-bit (6.9 GB) needs about 7.1 GB in use, so 8.9 GB of the 16 GB stays free: room for a larger image, a LoRA or a ControlNet.

“Needed” adds 1.2 GB of working memory for SDXL and a 0.8 GB reserve. Sizes 2026-10-01. The 6.94 GB checkpoint also holds the two text encoders and the VAE. During sampling only the UNet (about 5.1 GB at 16-bit, 2.6B parameters) has to sit in VRAM, so that is the figure used for the 16-bit file.
03The text encoder
The text encoder is inside the checkpoint, so there is nothing extra to download.
