Leela Zero is an open-source, community-based project attempting to replicate the approach of AlphaGo Zero. It has reached superhuman strength. A Windows binary is available, but it can also be compiled for Mac and Linux.

You can play against Leela Zero by using any GTP-compatible GUI. There are also web based software that let you review your games using Leela Zero.


Follow the instructions given at [ext] https://github.com/gcp/leela-zero.

For Linux you need to build it yourself, and you may be unable to build from release 0.17 ([ext] bug #2378.

(Could add tips here based on our experience)

See also LeelaZero / Patrick Traill on Linux for the tale of how he got the GPU running but ended up with a dysfunctional laptop battery.


Tournaments and matches

Online versions

Leela Zero v 0.16 is playing 19x19 games on DragonGoServer. It runs with a thinking time of 1 minute without GPU support. An update is currently impossible as, alas, version 0.17 does no longer run without GPU support. It's strength on DragonGoServer is 4 dan, due to high handicap games that it cannot cope with. Last Update: September 2020.
