Genmo
Genmo is a research lab building open video world models, with Mochi as its flagship text-to-video line. You can try generation in the browser playground, download weights for local runs, or plug into partner APIs. The team frames video as a path toward world simulators that understand physics, motion, and scene continuity.
Mochi 1 is their first major public release: a 10-billion-parameter diffusion model under Apache 2.0, trained from scratch on an Asymmetric Diffusion Transformer architecture. The preview outputs 480p clips at 30fps for up to 5.4 seconds, with emphasis on prompt adherence and realistic motion rather than static frame polish.
Researchers and developers get open weights on Hugging Face, source on GitHub, and ComfyUI support for custom pipelines. Creators and marketers use the hosted playground to prototype scenes without running GPUs locally. The lab also publishes technical writeups and benchmarks comparing Mochi against closed commercial video generators.

Preview clips cap at 5.4 seconds and 480p resolution today.
Image-to-video input is listed as coming soon, not available yet.
Free tier exports include a Genmo watermark and only 50 monthly credits.
Is Genmo free to use?
Yes. Genmo offers a Free plan at $0 per month with 50 credits monthly, though generated videos include a Genmo watermark. Paid Lite and Standard plans remove the watermark and add more monthly credits.
How long can Genmo videos be?
Genmo's Mochi 1 preview generates videos up to 5.4 seconds long at 30 frames per second. The team has noted that longer generation is in development.
What video format does Genmo output?
Genmo exports generated videos as MP4 files with H.264 encoding. The base Mochi 1 model produces 480p resolution, with higher resolutions available on paid plans.
Is Mochi 1 open source?
Yes. Mochi 1 is released under the Apache 2.0 license for both personal and commercial use. Weights are on Hugging Face and source code is on GitHub at github.com/genmoai/mochi.
What subscription plans does Genmo offer?
Genmo offers Free, Lite, and Standard plans billed monthly or yearly. Lite is $10 per month with 1,200 credits, and Standard is $30 per month with 5,000 credits. Each Mochi video generation costs 100 credits.
Can I download videos from Genmo?
Yes. Genmo lets you download any generated video from the playground. Downloads stay available for 30 days after generation.
