On-device Sora is an open-source project aimed at enabling efficient video generation on mobile devices (such as the iPhone 15 Pro) using technologies like Linear Proportional Jump (LPL), Time Dimension Tag Merging (TDTM), and Concurrent Inference with Dynamic Loading (CI-DL). Developed from the Open-Sora model, it generates high-quality videos based on text input. Its main advantages include efficiency, low power consumption, and optimization for mobile devices. This technology is applicable in scenarios that require rapid video creation on mobile devices, such as short video production and advertising. The project is currently open source and can be used free of charge.
