A public website, now called Arena, where people compare answers from two anonymous [AI models](https://ecosystem.samcarlton.com/model) and vote for the better one. The votes produce a [leaderboard](https://ecosystem.samcarlton.com/benchmark).

**For example:** A [founder](https://ecosystem.samcarlton.com/founder) looks at the Arena [leaderboard](https://ecosystem.samcarlton.com/benchmark) to see which models people prefer for [coding](https://ecosystem.samcarlton.com/code) questions.
