Arena
Domain: Evaluation
🎯 Motivation
A platform where users ask questions, two anonymous models answer, and users vote on the better answer. Live leaderboard.
📋 Concrete Example
LMSYS Arena: you ask a question. Model A and Model B both answer (you do not know which is which). You vote. Rankings update in real-time. Crowd-sourced evaluation.
🔗 Analogy
A blind taste test at a food fair - you try two dishes without knowing the chefs, and vote for the better one. Arenas are blind taste tests for AI models.
