Showcase

Direct R2E5 @ 0.8 outputs, no retouching. Euler a, 28 steps, CFG 4.5, CLIP skip 2, 832×1216 ; Hires / ADetailer off.

Trigger Words and Settings

Captions used keep_tokens = 2 , shuffle_caption = true . Dataset: 37 image/caption pairs. num_repeats = 5 on the resume run. Network dim 32 / alpha 16, AdamW 8-bit, UNet + both text encoders, bf16, SDPA, 1024 buckets. Training log does not print LR, so this card does not invent one.

Recommended: waiIllustriousSDXL v17 / Illustrious family; strength 0.8 . Euler a, 28, CFG 4.5, CLIP skip 2, 832×1216 .

Why R2E5

Round 1 screened both runs at 0.8. Round 3 matrix used candidates R1E3 / R2E5 / R2E6 across 10 scenes × 0.4/0.6/0.8/1.0. R2E5 best balanced face cleanliness with school-uniform / armband fidelity at 0.8; R2E6 is close but locks harder at 1.0. See evaluation/横向测评记录.md .

Public Horizontal Evaluation

Sheets: columns = candidates (R1E3 / R2E5 / R2E6), rows = weight 0.4–1.0. Original outputs scaled with labels only — no retouching or swapped images.

Compatibility and Limits

Scored on waiIllustriousSDXL v170. At low weight, prompts with only the name can drift toward generic shrine-maiden clothes — use miko_school_uniform explicitly. High-school character.
