// Questions
FAQ
Does it cost anything to join?
No. Claiming a spot and building in a Yard is free.
Can I use any AI model?
Almost always, yes. Bring whatever you use, or no AI at all. The theme is the constraint, not the model. A Yard can name a model (usually a sponsor's), and its page says so up front.
What if I can't make it?
Release your spot so the waitlist moves. And if you don't check in before kickoff, your spot releases on its own, so a full Yard stays a Yard full of builders.
What do winners get?
The Champion badge on your profile, a spot in the Hall of Fame, a featured writeup, and a year pinned to the home page. Some Yards add a cash prize pool, stated up front.
