CodeDuel: Compete against AI

I like what you've built here, I don't think I've ever seen anything like this. Competing directly against Claude is a fun challenge, and the detailed scoring makes it feel like you're actually improving your skills instead of just checking whether your code passes. I would love to see more models to compete against in the future, I think Gemini could be a decent competitor too 👀

Shoutout to the team that worked on this! 👍
