As an open-source, state-of-the-art tool, Mochi 1 enables the creation of videos with high-fidelity motion and remarkable adherence to user prompts. In this blog, we will delve into Mochi 1’s functionalities, its architectural design, and how to effectively set up and run the Txt2video workflow using ComfyUI.

What it Mochi 1

Mochi 1 is an open source, state-of-the-art video generation model releasing under the Apache 2.0 license, developed by Genmo AI. It produces videos with high-fidelity motion dynamics and exhibits a remarkable ability to adhere to user prompts. Currently, a foundational 480P model is available on Hugging Face, allowing individuals and businesses to use it for commercial purposes free of charge.

Mochi 1 Evaluation and Limitations

Mochi 1 stands out in the rapidly evolving landscape of AI video generation models due to its advanced architecture and impressive capabilities. The foundational 480P model released by Genmo AI boasts numerous advantages. Compared to other video generators, Mochi 1 can produce videos at a smooth frame rate of 30 frames per second for up to 5 seconds. However, it's important to note that slight distortions or deformations may occur in extreme action scenarios. Additionally, the characters and scenes in the videos exhibit a high degree of temporal coherence and realistic motion dynamics, offering several noteworthy benefits, including but not limited to:

Motion quality

Mochi 1 is known for its ability to produce realistic motion dynamics by effectively understanding and applying principles of physics. This includes simulating fluid movement, which allows for lifelike interactions with water and other liquids, as well as accurately representing the behavior of fur and hair, giving characters a natural and believable appearance.

Prompt adherence

Mochi 1 is recognized for its remarkable ability to adhere closely to user instructions, especially when prompts are clear and concise. When users articulate their ideas in a straightforward manner, the model can effectively interpret and translate those instructions into high-quality video content. This responsiveness allows for precise control over various elements of the generated video, such as character actions, settings, and overall themes.

Mochi 1 Archetecture

Mochi 1 is a diffusion model with 10 billion parameters, built on the novel Asymmetric Diffusion Transformer (AsymmDiT) architecture. It is the largest publicly available video generation model to date, featuring a straightforward design that allows for easy modifications. Apart from Mochi 1, the video VAE has also been open-sourced. This VAE can compress videos to one-twelfth of their original size by utilizing 8x8 spatial compression and 6x temporal compression, transforming them into a 12-channel latent space.

This process not only significanly reduces the data size but also preserves essential information, enabling efficient processing within the model. By converting videos into a more manageable format, the VAE facilitates quicker generation times and allows Mochi 1 to perform complex video tasks with enhanced efficiency.

Step 1: Installation of Mochi 1 and VAE Models

How to Install MochiWrapper on ComfyUI

To run the latest text-to-video Mochi 1 models on ComfyUI, you will first need to download them from Hugging Face to your local computer and then upload them locally. However, to enhance user convenience, MimicPC has integrated the existing Mochi 1 models directly into ComfyUI, eliminating the need for additional downloads from Hugging Face. The models highlighted in red in the image below are available for use for Mochi 1. You can choose based on your specific requirements, but keep in mind that larger models require more advanced computer specifications.

2. Mochi GGUF Q8:

Performance: This version typically offers a good balance between model size and performance, suitable for generating high-quality video with reasonable resource requirements.

3. Mochi bf16:

Performance: This format is optimized for training and inference in AI models, balancing precision and performance. It allows for faster processing while maintaining better numerical stability than FP8.

4. Mochi fp8:

Performance: Designed for efficient memory usage and faster computation, making it suitable for environments with limited resources. However, it may sacrifice some precision compared to higher-bit formats.

Once the model have been downloaded, it need to be uploaded to the following directory: Storage > models > diffusion_models > mochi, the steps outlined below:

Step 2: Generate Video With Our Click-And Run Workflow

Start by selecting the hardware that best suits your needs and computer specifications. We recommend choosing the Ultra option when running this workflow, as it provides optimal performance and ensures a smoother experience with higher processing capabilities.

Then, select the model you downloaded from the red section labeled ''(Down)load Mochi Model.'' Make sure to double-check that you have the correct version, as different models may offer varying features and capabilities.

Next, input the desired video effect in the prompt section, ensuring that your instructions are clear and specific. This will help the model accurately interpret your vision. For example, you might describe the type of mood or atmosphere you wish to convey—whether it’s a vibrant, energetic scene or a calm, serene moment.
