}Evidence claims
- [upstream_claim] README claims an infinite-length film model via a Diffusion Forcing framework with per-token noise levels; demos 30-second clips; evaluation numbers are the authors' own human and VBench results. source
- [upstream_claim] README: 540P 1.3B needs ~14.7 GB peak VRAM, 14B 540P ~43.4 GB (T2V) / ~51.2 GB (diffusion forcing); 5B and Camera Director listed as coming soon; SkyReels-V3 released in a separate repo (news dated 2026-01-29). source
- [upstream_claim] HF card for SkyReels-V2-DF-14B-540P lists license 'skywork-license' and describes sync (10 s) and async (30 s) long-video modes. 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.
