RealGrade Air IL is the softest rung of the ladder, still clearly semi-real with PerfectDeliberate structure and only a light touch of Nova Reality's photographic skin.

[Recipe] Weighted merge on UNet only: 0.80 x PerfectDeliberate v10 + 0.20 x Nova Reality XL IL v9.0. VAE and text encoders are inherited from PerfectDeliberate. Illustrious-family checkpoint, fp16 safetensors, no baked LoRA.

[Series] RealGrade IL is a four-rung realism ladder on the same two parents: Air 80/20, Balance 65/35, Form 45/55, Cinema 25/75. Choose the amount of photographic realism you need instead of downloading an undocumented remix.

[Recommended settings] Euler a, 24-28 steps, CFG 5.0-5.5, 832x1216. Hires fix holds up well above 1.25x.

[Known limitations] Two-person prompts frequently collapse to a single subject - this comes from both parents and reproduced in every seed tested. East Asian facial priors dominate unless ethnicity is stated explicitly. Illustrious-family only: do not load this in SD 1.5 or SDXL workflows. At 80% PerfectDeliberate the output stays deliberately semi-real, so do not expect photographic skin from Air.

[Parents and license] PerfectDeliberate v10: https://civarchive.com/models/24350 ; Nova Reality XL: https://civarchive.com/models/453428 . Both parents permit derivatives, Civitai generation and other generation services (Rent). The parents do not grant selling this checkpoint or its merges. Parent credit is retained.
