Aider Polyglot Leaderboard: AI Models Ranked by Score
Data updated
What Aider Polyglot measures
225 coding exercises in six programming languages. The AI edits the code files and the exercise's tests decide pass or fail.
Scores are percentages and higher is better. Results come from Epoch AI's open benchmark data; we do not run the test ourselves.

How to read this leaderboard
Scores are percentages and higher is better. For each model we show the best result Epoch lists across its effort settings, the same rule for every model. A gap of a point or two is usually within the normal noise of a test, so treat close scores as a tie. Newer models can be missing when nobody has run the test on them yet, so check the release dates. A benchmark measures one kind of skill: use it together with the overall leaderboard rather than on its own.
Questions people ask
What does Aider Polyglot measure?
225 coding exercises in six programming languages. The AI edits the code files and the exercise's tests decide pass or fail.
Who ran these tests?
The results come from Epoch AI's open benchmark data. It combines runs by Epoch with results published by other groups, and Epoch's own pages say which is which. We do not run tests ourselves.
Does a high score mean the model is best for me?
Not by itself. Aider Polyglot checks one kind of ability. A model can lead here and still be slower, costlier or a poor fit for your work. Compare it on the overall leaderboard and try it on your own tasks.
Why is a model I know missing?
A model appears only when an open source has published results for it. New models can take days or weeks to be measured, and models with no published score are left out rather than guessed.
Where does the data come from?
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.
How often is this leaderboard updated?
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.
