=Network=
Networks were built by volunteers, uploaded into [[Stockfish#Fishtest|Fishtest]] for testing.
Networks with good test results are released officially on the Fishtest website <ref>[https://tests.stockfishchess.org/nns Neural Net download and statistics]</ref> with average speed of 2 week weeks per networks network <ref>[https://github.com/official-stockfish/Stockfish/discussions/3628#discussioncomment-1047323 One year of NNUE.... · official-stockfish/Stockfish · GitHub] by [[Joost VandeVondele]], July 26, 2021</ref>.
After long discussing the best way to publish networks with Stockfish <ref>[https://github.com/official-stockfish/Stockfish/issues/3030 Improve dealing with the default net? Issue ##3030 · official-stockfish/Stockfish · GitHub] by [[Joost VandeVondele]], August 19, 2020</ref>, the developing team decided to embed the default network into Stockfish binaries, making sure NNUE always works as well as bringing more convenience to users.
Being attracted by new advantages as well as being encouraged by some impressive successes, many developers joined or continued to work. The [[#Source|Official Stockfish]] repository shows the numbers of commits, ideas increased significantly after merging NNUE.
=Elo gain=
[[Joost VandeVondele]] has created a graph to show how Stockfish gains Elo with NNUE after a year:<ref>[https://github.com/official-stockfish/Stockfish/discussions/3628#discussioncomment-1047728 One year of NNUE.... · official-stockfish/Stockfish · GitHub] by [[Joost VandeVondele]], July 26, 2021</ref>
