Today’s update brings several improvements to the AI system:
- We now support both KataGo and Leela Zero engines.
- KataGo is now the default review engine, Leela Zero is available for 19x19 games by clicking the review list drop down and clicking the Leela Zero button.
- 9x9 and 13x13 games are now supported (by KataGo only)
- We’ve dropped support for the 15x128 Leela Zero network and now just use the 40x256 networks for all Leela Zero reviews. The playout settings have been adjusted to provide slightly stronger reviews than with the 15x128 network.
- You can now download SGF’s that have the analysis information
Right now we believe the review strengths have been tuned to be about the same or slightly better than they were before the release. We are planning on giving a boost to all KataGo review strengths, but we want to see how the servers hold up to the addition of the 9x9 and 13x13 games first.
As always, let us know if you have any issues with the new system. I have fixed the things I know I broke this morning, but I’m sure there are still some issues lurking.
