Lazy Baduk

A Go game analysis tool for Android, providing the power of Leela Zero on your smartphone.

Leela Zero is a strong Go bot, created as an independent implementation of the Alphago Zero deep learning algorithms. It's now so strong that even on a phone, with relatively few playouts, it can achieve a high dan level.

Note that Leela Zero's analysis uses as much CPU power as it can, and will rapidly burn through battery power if not charging.


Lazy Baduk is available on Google Play. This version currently uses the last 15x192 network, from July 2018, in order to try to be as fast as practical on a phone. Larger networks take longer to initialise and to generate playouts.

Versions incorporating other networks are available for direct download:

Technical details

Lazy Baduk is written in Python using Kivy. This means that it can also run on the desktop.

The app includes a Leela Zero binary compiled for Android, so all analysis is run on your device. It does not currently use the GPU, although it might be possible to compile a version supporting OpenCL for devices that support it.
