There is an important bug fix in 0.21.0 version of lc0 engine. This version is now mandatory for training, please upgrade ASAP if you have not already done so.

This is the testing instance of LCZero server.
Here we pretend to test things but sometimes actually run things to completion.
We have started another major run that aims to demonstrate a lot of what we have learnt so far, rather than being subject to continual tweaks. Main page will show its progress. Other test runs can be seen under the training runs section.
You can get the client and lc0 releases from those links.
