[2] The engines were originally authored by Don Dailey and GM Larry Kaufman.

Dragon is a commercial chess engine, but Komodo is free for non-commercial use.

[4][5][6][7][8] Komodo was derived from Don Dailey's former engine Doch in January 2010.

[12] On October 8, Don made an announcement on the Talkchess forum that Mark Lefler would be joining the Komodo team and would continue its development.

This was the same version that had won TCEC Season 5, and was the last with input from Don Dailey, to whom it was dedicated.

The advent of the neural network engine Leela Chess Zero meant Komodo has largely failed to qualify for the superfinal since, with a single exception in Season 22, when it lost to Stockfish.

Although Komodo has not qualified for the superfinal, it has cemented itself as the third-strongest engine in the competition, finishing in that position for five of the last six seasons.
