Mochi 1 is a revolutionary 10 billion parameter diffusion model from Genmo AI, released in late October 2024 following a $28.4 million Series A funding round. As the largest video generative model ever openly released, Mochi 1 represents a significant milestone in democratizing access to state-of-the-art video AI technology.
Novel Asymmetric Diffusion Transformer Architecture
Built on Genmo's novel Asymmetric Diffusion Transformer (AsymmDiT) architecture, Mochi 1 achieves exceptional performance in generating smooth, photorealistic videos at 30 frames per second for durations up to 5.4 seconds. The model excels at simulating complex physics including fluid dynamics, fur and hair movement, and consistent human action.
Apache 2.0 License: Complete Commercial Freedom
Released under the permissive Apache 2.0 license, Mochi 1 is completely free for both personal and commercial use. The preview version generates videos at 480p resolution, with full HD support planned before the end of the year. Open weights and architecture are available on HuggingFace.
Advanced Physics Simulation
- Fluid dynamics simulation for water, smoke, and liquids
- Fur and hair physics with realistic movement
- Human motion capture with natural gestures
- High temporal coherence across frames
- Realistic motion dynamics without artifacts
Real-World Applications
Commercial video production without licensing restrictions, photorealistic content creation for marketing, research into diffusion-based architectures, custom model fine-tuning for specific visual styles, and social media content generation for Reels, TikTok, and Shorts.
