## Frequently asked questions

### What is the best AI in 2026?

By community preference (Arena Elo) the top is held by frontier models from Anthropic, OpenAI and Google. The practical answer depends on your use case, coding, reasoning and price each produce a different winner, which is why we publish one leaderboard per dimension.

### What is Arena Elo?

Chatbot Arena shows people two anonymous answers to the same prompt and asks which is better. Each vote updates an Elo rating, the same system used in chess. It is the closest thing to a blind taste test for AI models.
