Scores and API prices on this page are refreshed from published evals and provider rates. The snapshot is labeled August 20, 2026. Treat it as a current index, not a one-off blog post.
Nanogpt is a public LLM eval (the Nanogpt score). This page ranks models that have published a score, next to live API prices.
This page is the Nanogpt leaderboard. Models are sorted by Nanogpt, 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 Nanogpt score next to live API $/M so you can pick a production SKU, not only a trophy number.
