At a glance

THUDM's open AI video model supporting longer outputs and self-hostable inference.

Editor's note: Best for Researchers exploring long-form open video models. The main caveat: h100 access for inference is realistically a cloud bill of $3-4/hr.

Strengths

• 8-second clips, longest open-source duration today
• MIT license on inference code, generous for commercial use
• Trained on a wider style distribution than SVD, less rigid
• Works on a single H100 GPU end-to-end

Weaknesses

• H100 access for inference is realistically a cloud bill of $3-4/hr
• Command-line workflow only, no UI
• Documentation in English is sparse, much is Chinese-only
