Trigger Words and Settings

Captions used keep_tokens = 2 , shuffle_caption = true . Dataset: 17 image/caption pairs, all maki_casual . num_repeats = 10 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 (0.6 already recognizable; 1.0 turns the face / locks accessories). 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 / R2E4 / R2E5 across 10 scenes × 0.4/0.6/0.8/1.0. R2E5 was the most balanced for face, casual full-body, night, and leak control. See evaluation/横向测评记录.md .
