The second line of the article: "The engine with 5 kN (500 kg / 1124 lbf) of thrust, generated the expected 20,000 horsepower"

Specific impulse would also be nice, thrust itself isn’t very impressive

I think the impressive thing here is more that they asked the computer to design an engine which produced a desired amount of thrust, and it did so.

The thing being demonstrated isn’t ‘we made this engine, look how impressive its specs are’, it’s ’our computer can make working engines to spec’
