}Evidence claims
- [upstream_claim] README: LongLive 1.0 accepts sequential user prompts and generates video in real time; ICLR 2026; 20.7 FPS on one H100 counting diffusion time only (excludes VAE decode); news through 2026-10-08. source
- [upstream_claim] HF card: LongLive-1.3B supports up to 240-second videos, 24.8 FPS with FP8, needs an NVIDIA GPU with >= 40 GB; weights under CC-BY-NC 4.0. 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.
