Artemis, Hypnos and Killfish wins New Engines Test, 2026.01.28 - 2026.02.02

on

 Final Standings


Here are the results from another tournament featuring new chess engine versions. Artemis 26.3TR PrO, HypnoS EN 1.0, and Killfish PB 260126 tied for first place.

What's the reason for this?
Artemis 26.3TR PrO, HypnoS EN 1.0, and Killfish PB 260126 are all based on the Stockfish source code. As we’ve seen, there has been little significant progress in Stockfish's development recently, meaning performance differences between these derivatives remain minimal. Stay tuned—more tests are coming soon!

Even though the benchmark engine Critter 1.6a is already 14 years old, it still outperforms many newer engines. That’s why we continue to use it in our tests — any new engine capable of beating Critter clearly deserves further evaluation and the attention of the chess community.

Several new chess engines also took part in the tournament: Gyatso, Aconcagua, Deep Becky 0.2, and Marvin-onnx 1.0.1. As you can see, they performed very poorly and finished last in the table. 
These weakest engines will no longer be tested by us, nor will they participate in the qualifying rounds for the chess engine league (TOP-64).
