A Modal cert sweep caught what the research doc missed: PhotoMaker-V2 fails at
import without InsightFace ("No module named 'insightface'"). Reading the upstream
source confirms it: `photomaker/__init__.py` imports `FaceAnalysis2` (an InsightFace
wrapper) at module load, V2's encoder is named
`PhotoMakerIDEncoder_CLIPInsightfaceExtendtoken`, and `model_v2.py`'s forward
takes an `id_embeds` argument that the pipeline computes via
`insightface.app.FaceAnalysis(name='antelopev2', ...)`. So V2 is a DUAL encoder
(CLIP + ArcFace), not CLIP-only as the model card line "id_encoder includes
finetuned OpenCLIP-ViT-H-14 and a few fuse layers" implied.
InsightFace's pretrained model packs (antelopev2, buffalo_l) are research/
non-commercial only per their own README:
"The pretrained models we provided with this library are available for
non-commercial research purposes only."
So V2 is blocked for a paid service like raiw.cc.
PhotoMaker-V1 is the commercial-safe alternative — its `PhotoMakerIDEncoder`
(model.py) forward takes only `(id_pixel_values, prompt_embeds, class_tokens_mask)`,
no ArcFace branch. Identity is CLIP-only, license is Apache-2.0, no InsightFace.
Code change: swap the repo + filename constants in `photomaker_restore.py`
(TencentARC/PhotoMaker, photomaker-v1.bin). Tests still pass (the 9 PhotoMaker
tests use a fake pipeline, so the model swap is transparent to them).
Doc correction: rewrote the verdict / license table / section 5 of
`docs/synthid-robust-identity-research.md` to lead with V1 and add a correction
notice explaining the V2 misread. Bulk-renamed `PhotoMaker-V2` to `PhotoMaker-V1`
across CLAUDE.md, README.md, docs/synthid.md, and
docs/controlnet-removal-pipeline-research.md (kept V2 only in the correction
notice, the license table, and the anchor reference).
ruff clean; 578 tests pass.
