Notes: UNet 2.6B (3.5B with CLIP-L + OpenCLIP-G; no T5). The two CLIP encoders total ~1.6GB and stay resident, so peak VRAM is the sum: ~7.5GB measured at 1024x1024 on an 8GB card, matching Stability's stated 8GB minimum. Runs on 4GB with AUTOMATIC1111 --lowvram, slowly. An optional refiner adds a second ~6GB UNet. Sources: Stability SDXL announcement, ComfyUI 8GB measurement, AUTOMATIC1111 Optimum SDXL wiki.
