}Evidence claims
- [upstream_claim] README lists T2V 1.3B and 14B, I2V-14B 480P/720P, FLF2V-14B 720P and VACE 1.3B/14B variants, weights under Wan-AI on Hugging Face and ModelScope. source
- [upstream_claim] README states T2V-1.3B needs about 8.19 GB VRAM and makes a 5-second 480P video on an RTX 4090 in about 4 minutes without optimization; suggests --offload_model True and --t5_cpu for OOM. source
- [sourced_fact] Repository LICENSE.txt is the Apache License 2.0 text. source
- [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.
