HunyuanVideo (v1, commit 4eda9cb44c3be82a6b9c4261897cb6bd3cfb084e): batch-size-1 peak memory 60GB at 720x1280x129 frames and 45GB at 544x960x129; tested on a single 80GB GPU; 80GB recommended; FP8 weights save about 10GB; 8-GPU latency table for 1280x720, 129 frames, 50 steps (1904.08 s on one GPU). HunyuanVideo-1.5 (commit 60783e704160023913bee78f0b47036d393d4dfa): 8.3B parameters, minimum 14GB with offloading (setting not stated), 480p and 720p models with optional super-resolution to 1080p, default 121 frames, a 480p I2V step-distilled model said to reach 75 seconds on one RTX 4090. The two READMEs do not give the same kind of figure, so they cannot be compared directly.

The two READMEs do not give the same kind of figure, so they cannot be compared directly.

Curator qualifications: Verified the HunyuanVideo v1 peak figures and the 1.5 offloading minimum. The figures are of different kinds, as stated.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
