Pyramid Flow, a new open-source AI video generator, has launched, enabling the creation of high-quality video clips up to 10 seconds long. Developed by researchers from Peking University and Kuaishou Technology, it employs a novel pyramidal flow matching technique to enhance efficiency and reduce computational costs. While it offers impressive video quality, it currently lacks some advanced features found in proprietary models, positioning it as a competitive alternative in the evolving AI video generation market.
