Meituan Unveils LongCat-Video: An Open-Source AI Video Generation Model
Meituan, a leading technology platform, has released LongCat-Video, a new open-source AI model capable of generating high-quality videos from text, images, or existing video clips. The model is designed for efficient long-video generation and boasts performance comparable to leading commercial solutions.
Key Capabilities & Technical Features:
LongCat-Video distinguishes itself through several core technologies:
* Unified Architecture: The model utilizes a single framework to handle diverse tasks including text-to-video, image-to-video, and video continuation, streamlining processing through shared architecture and parameters.
* Long Video Generation: Specifically trained on video continuation, LongCat-Video can generate videos lasting several minutes while maintaining coherence and quality.
* Efficient Reasoning: A coarse-to-fine generation strategy, coupled with Block Sparse attention technology, allows for the rapid generation of 720p videos at 30fps – achievable in just a few minutes.This combination improves reasoning efficiency, particularly for high-resolution outputs.
* Multi-Reward Reinforcement Learning: the model is optimized using Multi-reward Group Relative Policy Optimization (GRPO), resulting in performance on par with leading open-source and commercial video generation models, as demonstrated in both internal and public benchmarks. This optimization focuses on improving text alignment, visual quality, and motion quality.
