magi-1-24b is a large-scale diffusion-based video generation model built to produce realistic, coherent videos from text prompts, supporting frame lengths up to 4 seconds at high resolution. Developed by Sand AI and released under an open license, it aims to democratize video synthesis with performance on par with or exceeding leading closed-source models.
Its training strategy blends masked video modeling, spatial-temporal consistency learning, and multimodal alignment, making it particularly strong at maintaining identity, structure, and scene logic across time.
Key Features
- Diffusion Video Generation: Built upon denoising diffusion probabilistic models, magi-1-24b generates videos by gradually refining a sequence of noise vectors into photorealistic motion. This method allows for exceptional control over motion dynamics and frame coherence.
- High-Quality, Temporally Consistent Motion: Unlike typical short-sequence models (e.g. 2s), magi-1-24b produces videos up to 64 frames (~4 seconds) while maintaining consistent character identity, background, and action flow.
- Strong Visual and Structural Fidelity: The model excels at rendering detailed scenes, capturing fine-grained textures, object interactions, and realistic human body poses.
- Multimodal Conditioning: magi-1-24b supports text-to-video (T2V) generation with alignment across spatial and temporal dimensions, making prompt-driven video creation more precise and reliable.
- Extensive Benchmark Testing: In public evaluations, magi-1-24b outperformed all tested open-source models across key metrics like FVD (Fréchet Video Distance), human preference, and identity consistency. See benchmark table below.
ComfyUI
magi-1-24b is also available on ComfyUI, providing local inference capabilities through a node-based workflow. This ensures flexible and efficient video generation on your system, catering to various creative workflows.
Limitations
- Fixed Video Duration:Currently supports videos up to 64 frames (~4 seconds). Longer video storytelling may require post-generation stitching or separate tools.
- Single-Prompt Focus:magi-1-24b is optimized for single-prompt outputs. Multi-shot or sequential storytelling requires creative prompt structuring.
- Still Under Open Development:While powerful, Magi-1 is still evolving. Advanced capabilities like consistent character re-use or camera movement controls are limited in this version.
Out-of-Scope Use

- Exploiting, harming, or attempting to exploit or harm minors, including solicitation, creation, acquisition, or dissemination of child exploitative content.
- Generating or disseminating verifiably false information with the intent to harm others.
- Creating or distributing personal identifiable information that could be used to harm an individual.
- Harassing, abusing, threatening, stalking, or bullying individuals or groups.
- Producing non-consensual nudity or illegal pornographic content.
- Making fully automated decisions that adversely affect an individual’s legal rights or create binding obligations.
- Facilitating large-scale disinformation campaigns.
