CoArena

ActiveAI-native

The biggest crowdsourced benchmark for Computer-Use

What it does

CoArena is a live arena where anyone can use the world's top computer-use models racing two of them on the same real computer task and judging which one did it better. Every battle becomes something the AI labs can't build themselves, an honest test of their agents on real work, and the data to make them better.
