DarkQueen uses lichess games that have been annotated by Stockfish. Bad Gyal 7 uses lichess games annotated with q and policy from Stockfish. The main difference seems to be policy. So far it's a walkover by the smaller Bad Gyal 7. Here a sample game:

brianr wrote: ↑Thu Aug 29, 2019 7:28 pm FWIW, it is quite a lot stronger than that, I think, at least on the hardware below.

I trained a large 320x24 net and played against Stockfish 7 on one CPU (i5 3570K, 3.4GHz, boost to 3.8)
My net was clearly stronger on an RTX 2060 (I know, not a favorable "Leela Ratio" for SF).

Code: Select all

Score of SF7 vs T60-320x24-74000-Steps: 6 - 21 - 13  [0.313] 40
Elo difference: -136.97 +/- 94.70, LOS: 0.19 %, DrawRatio: 32.5 %

Then, I played my net against Bad Gyal 7:

Code: Select all

Score of Bad-Gyal-7-DKappe vs T60-320x24-74000-Steps: 122 - 94 - 284  [0.528] 500
Elo difference: 19.48 +/- 20.00, LOS: 97.16 %, DrawRatio: 56.8 %

On CCRL at 40/40 SF7 1 CPU is 3,245; again, my hardware is quite different.

Although larger nets should be able to learn more, they also take a lot more training time I think.
Thus the much faster speed of Bad Gyal 7 seems to more than make up for its smaller size.

To be sure, one could match SF7 vs Bad Gyal 7 directly.

Conditions:
6 piece Syzygy tablebases
2 move opening book
Time control 0:10+2.0
