Oliver Prompts(@oliviscusAI):this repo beat Runway Gen-3 and Luma 1.6 in blind human evaluation. it also needs 60GB of VRAM for one video. - text alignment: 61.8%, best of the 6 - motion quality: 66.5%, best of the 6 - overall preference score: 41.3%, ranked #1 a 13B parameter model, largest open-source video model at release, using a decoder-only LLM as the text encoder instead of CLIP+T5. this is the original HunyuanVideo though. Tencent's own HunyuanVideo-1.5 replaced it since, same lineage, far lighter to run.
