Has anyone here actually tested HappyHorse on Arena AI?

Yesterday, HappyHorse 1.0 officially announced that it was added to Arena AI, and it also ranked No. 1 in video editing. I signed up for Arena AI to test it, but right now it seems to allow only 2 tests every 24 hours. From what I understand, you compare two videos blindly, choose which one looks better, and then Arena reveals which models they were generated with. So far, I’ve only run into models like Kling, Veo 3, and Grok. I still haven’t matched with HappyHorse yet.
