LongLive 2.0

NVIDIA open-sourced this NVFP4 long-video infrastructure in May 2026 under Apache 2.0, built on Wan2.2 5B. Two-step NVFP4 inference reaches 45.7 FPS (diffusion time only) with multi-shot and long-sequence support; the README does not state a minimum VRAM, and FPS was measured on one GB200 (180GB).

Weights are free, hardware is not: you buy the GPU up front (one-time estimate, may rise) and still pay for power and time. Six of the twelve are Apache 2.0 (HappyHorse-1.0, SANA-WM, Bernini, MAGI-2, LingBot-Video, LongLive 2.0); LTX-2 and LTX-2.5 use community licences and SANA-Video uses the NVIDIA Open Model License. Hardware runs from one RTX 5090 to 8× H100. See all 12 →
