Pro Tips for Best Results
Use clear, well-lit, front-facing faces.
Prefer one clear face per photo.
High-resolution crops beat tiny faces in a group shot.
Illustrated or heavy stylization can lower scores even for the same character.

Use cases
- QA AI portrait batches against a real reference
- Rank LoRA or character generations by face match
- Shortlist headshots against a brief face
- Score event candids against one person
Rank many photos against one face
Batch face comparison is for when two photos are not enough. Keep one reference face fixed, upload a set of candidates, and sort by similarity so the strongest matches rise to the top.
Creators use this for LoRA and character consistency checks. Casting and shortlisting work the same way: one brief face, many options, ranked scores.
