Dragon by Komodo Chess [1]
Logo at TCEC

Dragon by Komodo Chess, (KomodoDragon, Komodo Dragon)
a version of Komodo which combines an NNUE based evaluation with Komodo's search, either classical alpha-beta as well as MCTS. Dragon was announced on November 02, 2020, and released as Dragon by Komodo Chess on November 10, 2020. Strength improvements for both search modes were given in the 150 (4 threads) to 190 (one thread) Elo range [2].

Dragon is the work of Larry Kaufman and Mark Lefler, who superseded original Komodo author Don Dailey after his death on November 22, 2013, further supported by Dmitry Pervov and Dietrich Kappe concerning the NNUE inference code and training data. The neural network was trained supervised by chess Grandmaster Larry Kaufman, along with reinforcement learning considering billions of positions and evaluations from Komodo games. Chess.com supported the project financially [3].
