Chatbot Arena (Document): leaderboard
Users upload their own PDFs and ask a model to answer questions about them, summarise them or extract insights from them. Two anonymous models reply side by side and the voter picks the better answer. Scores are a Bradley-Terry fit over those votes on an Elo-like scale with a confidence interval, and higher is better.
Metric: Elo. Source: arena.ai. Source: benchmarklist.com. Saturation forecast: Around January 2028. 44 models tracked.
