Here is the new CEDR chess engine ranking list as of January 1, 2025.

In November, our testers conducted chess engine tests in which over 28 thousand games were played. Thanks to this, the ranking is calculated based on 543,291 games!
The list only includes chess engines that have played at least 500 games in our tests.
The game database has been "cleaned" of games that had less than 10 moves.
