Video Arena has launched on the web at lmarena.ai/video, expanding from its origins as a Discord bot. Initially a small experiment, it has evolved into a platform for assessing the performance of advanced video models in real-world scenarios. The transition to a web-based platform broadens participation, allowing a more diverse range of users to contribute data. This diversity is essential for generating a more accurate leaderboard that reflects actual performance across various prompts and languages. Currently, the web version features Battle Mode, where users can compare 15 leading video models, including Google’s Veo 3 and Sora 2. Users can enter prompts or upload images to generate videos, then vote for their preferred output. These votes influence the Video Arena leaderboards, which will adapt as more users engage. The platform aims to refresh its leaderboard pipeline to integrate data from web interactions. Feedback from users is encouraged, with a specific channel on Discord set up for suggestions. This ongoing input will help improve the platform and enhance user experience. The launch marks a significant step in making cutting-edge video technology more accessible and participatory.
