Video Arena, initially a Discord bot, is now live on lmarena.ai/video, allowing more users to test and compare top video models. Users can submit prompts and vote on generated videos, contributing to leaderboards that reflect real-world performance. The platform aims to expand participation and improve the quality of data collected.

Databricks transformed its subreddit from a private community into an active space for user engagement and feedback. By involving employees and experienced moderators, they created a platform that generates valuable insights for their teams, attracting over 10,000 organic visits monthly.
