Repo Env is a public LLM eval (the Repo Env score). This page ranks models that have published a score, next to live API prices.
This page is the Repo Env leaderboard. Models are sorted by Repo Env, 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 Repo Env score next to live API $/M so you can pick a production SKU, not only a trophy number.
