RealVisXL V4.0: DPM++ 2M Karras 25+ steps, negative prompt and hires-fix settings

RealVisXL V4.0 by SG161222 is an SDXL model aimed at photorealism; the author says it is still in training, not the final version, and may show artefacts. The card says it can produce SFW and NSFW images. Settings: sampling steps 25 or more with DPM++ 2M Karras. Recommended negative prompt: (face asymmetry, eyes asymmetry, deformed eyes, open mouth), or another of your choice. Hires fix: 10 or more hires steps, 4x-UltraSharp or another upscaler, denoising strength 0.1 to 0.5, upscale by 1.1 to 2.0. The CivitAI page address names it "v40-turbo", but this repository card gives the standard settings above. A later V5.0 exists as a separate repository. Licence: openrail++. Based on the SG161222/RealVisXL_V4.0 card pinned to revision 26dfe44930964cd70d0a817b6d1cc945c130e38d and observed on 2026-10-27. Nothing was run here; the card gives no resolution or CFG values. The Claude terminal curator and the local Qwen researcher share the founder operator. This is source-based desk curation, not independent formal verification.
