A team of researchers from Peking University, Beijing University of Posts and Telecommunications, and Kuaishou Technology has launched the AI video generation model, Pyramid Flow. This high-quality generation tool leverages a new technique wherein a single AI model generates video in stages, most of them low resolution, saving only a full-res version for the end of its generation process.
What is Pyramid Flow?
Pyramid Flow is an innovative, open-source AI video generation platform. It is built on the concept of pyramidal flow matching, a method that drastically cuts down the computational cost of video generation while maintaining high visual quality, completing the video generation process as a series of “pyramid” stages, with only the final stage operating at full resolution.
The model takes only 56 seconds to generate a 5-second, 384p video, which is on par with or faster than many full-sequence diffusion counterparts. However, Runway’s Gen 3-Alpha Turbo still leads the field in terms of AI video generation speed, completing tests in under a minute and frequently taking 10–20 seconds.

Pyramid Flow AI: Features
Here’s a more detailed explanation of each feature of Pyramid Flow AI:
- AI-Powered Prompts: Pyramid Flow AI provides users with smart, AI-generated prompts that inspire video ideas. These prompts are based on the user’s input, such as a brief description of the desired video content or style. The AI analyzes this information and offers tailored suggestions for video structure, storytelling, or style, making the creative process smoother and more efficient, especially for those who struggle with ideation.
- Automated Video Editing: One of the standout features of Pyramid Flow AI is its ability to automate the video editing process. The AI handles tasks like trimming, stitching clips together, adding transitions, and syncing audio. It minimises the need for manual editing, which can be time-consuming and complex. With this feature, even users with little to no editing experience can create professional-quality videos with minimal effort.
- Scene Generation: The tool excels at creating dynamic scenes based on the script or prompts provided by the user. Using AI, it selects appropriate transitions, visual effects, and scene compositions to ensure smooth storytelling. This feature also helps with continuity, making sure that the entire video flows logically from one scene to the next. The user can also tweak scenes, allowing for creative flexibility while still saving time.
- Script and Voiceover Integration: Users can input their video scripts into Pyramid Flow, and the AI will generate corresponding video segments, complete with automated voiceovers if needed. The voiceover integration can use AI-generated voices or allow for custom narration. This feature is especially useful for tutorials, explainer videos, and presentations where narration is essential, ensuring that the visual and audio components are perfectly synchronised.
- Customisable Templates: Pyramid Flow offers a wide array of customisable templates, designed for different types of video content, such as marketing, product demos, social media posts, and educational videos. These templates provide a solid foundation for users to start with and can be adjusted to meet specific branding, tone, or thematic requirements. This feature significantly speeds up the creation process and ensures consistency across videos.
- Collaboration Tools: Pyramid Flow AI supports collaboration, allowing teams to work together on video projects in real time. Multiple users can contribute to different aspects of a video, such as editing, reviewing, or giving feedback. This feature is particularly beneficial for larger teams or agencies, ensuring that projects are completed faster with input from all necessary stakeholders while maintaining quality control.
- User-Friendly Interface: The platform’s interface is designed to be intuitive and easy to use, making it accessible to both beginners and experienced video creators. The layout, tool placement, and design ensure that users can navigate through the video creation process without confusion. Whether it’s uploading content, selecting effects, or exporting videos, the workflow is seamless and straightforward, reducing the learning curve for new users.
Pyramid Flow is available as raw code for download on Hugging Face and Github. It can be used even for commercial/enterprise purposes—and is designed to compete directly with paid proprietary offerings such as Runway’s Gen-3 Alpha, Luma’s Dream Machine, Kling, and Haulio.
