Alpha Go Zero inspired the development of an open source version, Leela Go Zero which Leela Chess Zero is forked from by the same guy who made Stock Fish.

Lots of people contribute what I imagine are amounts of CPU Power/money to the Leela Chess Zero project[1].

Would love to see Alpha Chess vs Leela Chess.

[edit] I've caused terrible confusion by melding Leela Go and Leela Chess when Leela Chess was originally forked from Leela Go and that's basically when similarities end.

Edited for a bit more clarity.
