Evidence claims:
- [upstream_claim] README: 'Lifelike Audio-Driven Portrait Animations through Editable Landmark Conditioning' accepted to AAAI 2025; inputs include audio, facial landmarks, pose or a driver video. · source: https://github.com/antgroup/echomimic
- [upstream_claim] README names EchoMimicV2 (semi-body human animation) and EchoMimicV3 (1.3B-parameter unified multi-modal, multi-task human animation) as follow-on repositories (their pages were not fetched). · source: https://github.com/antgroup/echomimic
- [upstream_claim] Tested configurations: A100 80G, RTX 4090D 24G, V100 16G; CUDA 11.7+; accelerated models reportedly about 50 seconds for 240 frames on a V100 versus about 7 minutes before acceleration. · source: https://github.com/antgroup/echomimic
- [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.
