    Where is the Aider leaderboard?

    This page is the Aider leaderboard. Models are sorted by Aider, with input and output token prices on the same row so you can weigh score against cost. Official boards often omit price; that comparison is the point of this index.

    Official eval pages own the methodology. This page keeps the published Aider score next to live API $/M so you can pick a production SKU, not only a trophy number.
