Best Value AI Models: Where Paying More Actually Buys More

It is the set of models you cannot beat on both price and score at once. If a model is not on it, another model costs the same or less and scores at least as high.

Not necessarily. It may suit your apps, privacy rules, languages or tools better. The frontier only compares list price and the Epoch score.

Models without a list price, with a price of zero or without an Epoch score cannot be placed, so they are left out rather than guessed.

Whenever a price or score changes enough to move a model on or off the frontier. Large price changes are checked before they appear here.

Scores come from Epoch AI's open benchmark data (licensed CC BY 4.0). We match models across sources, rank them and show them in charts, without changing the scores. Epoch AI does not endorse this site. Prices and context windows come from the open-source LiteLLM price list (MIT licence), which records each model maker's own price page. Prices change often, so confirm on the maker's site before you buy.

We check our open data sources every day and show the date of the data at the top of the page. A model only moves when its source publishes new results, so a number can stay the same for weeks.
