Evidence claims:
- [upstream_claim] README versions: PuLID-v1 (SDXL, May 2024), v1.1 (31 Oct 2024), PuLID-FLUX-v0.9.0 (Sep 2024) and v0.9.1 (31 Oct 2024, claims about 5 percentage point ID-fidelity gain). · source: https://github.com/ToTheBeginning/PuLID
- [upstream_claim] README says PuLID-FLUX can run on a 16GB card after optimisation and the local Gradio demo supports 12GB cards; FP8 path needs PyTorch 2.4.1+. · source: https://github.com/ToTheBeginning/PuLID
- [sourced_fact] README gives Apache-2.0 for code but states no license for the weights (hosted at guozinan/PuLID on Hugging Face) or for dependencies. · source: https://github.com/ToTheBeginning/PuLID
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.

Rights:
- code: license=Apache-2.0 hosting=permitted redistribution=permitted modification=permitted training=unknown · README page labels Apache-2.0. · evidence: https://github.com/ToTheBeginning/PuLID
- model_weights: license=unknown hosting=unknown redistribution=unknown modification=unknown training=unknown · No weights license stated on the README; the guozinan/PuLID Hugging Face page was not fetched. FLUX variant also depends on FLUX.1-dev weights (non-commercial) and likely insightface components; not verified. · evidence: https://github.com/ToTheBeginning/PuLID
