Vielen ist dieses Tool von Lc0 bekannt - clippy.

Nur für diejenigen, die es noch nicht eingesetzt haben:

Is "clippy" still concidered reliable ?
For games with ave. 1 sec/move to 15 secs/move should I use mbs=30 even though the nps is significantly slower ?```
{Lc0 --help}  --minibatch-size=1..1024
How many positions the engine tries to batch together for parallel NN
computation. Larger batches may reduce strength a bit, especially with a small
number of playouts.
