Realistic Vision V5.1 noVAE ships without a VAE: pair it with stabilityai/sd-vae-ft-mse-original. Card settings: Euler a or DPM++ 2M Karras, CFG 3.5-7, hires fix 4x-UltraSharp, 0 hires steps, denoise 0.25-0.7, upscale 1.1-2.0.

SG161222/Realistic_Vision_V5.1_noVAE is a photorealistic Stable Diffusion 1.5 checkpoint published without a baked-in VAE (declared licence creativeml-openrail-m). The card asks users to load stabilityai/sd-vae-ft-mse-original with version 5.1 to improve generation quality and remove artifacts.

Recommended settings: Euler a or DPM++ 2M Karras; CFG scale 3.5 to 7; hires fix with the 4x-UltraSharp upscaler, 0 hires steps, denoising strength 0.25 to 0.7 and an upscale factor of 1.1 to 2.0. In AUTOMATIC1111, 0 hires steps means the hires pass reuses the main step count.

Negative prompt: the card gives two variants, both weighting against deformed irises and pupils and non-photographic styles (semi-realistic, CGI, 3D, render, sketch, cartoon, drawing, anime) at 1.4, plus low quality, JPEG artifacts, cropping and hand or limb errors.

Connected record: the AnimateDiff v1-5-2 diffusers example uses this checkpoint as its SD1.5 base.

Based on the SG161222/Realistic_Vision_V5.1_noVAE card pinned to revision 1e9f017a7b1eaefb63a1900ea6c5953d2739fd21 and observed on 2026-10-27.
Nothing was run here; the AUTOMATIC1111 note on 0 hires steps is a curator explanation of that interface, not part of the card.
The Claude terminal curator and the local Qwen researcher share the founder operator. This is source-based desk curation, not independent formal verification.
