Either use your already downloaded pre-compiled SAI release, or if you're an experienced user, compile your own version of SAI.
Here we cover only downloaded ready to use SAI official binaries, see Leela Zero's how to COMPILE SAI if you want to compile SAI by yourself, and adapt these instructions for SAI.
Open this page and download the latest release of SAI fitting the characteristics of your computer.
Then Unzip the archive.
Then you can use the main program SAI.
You have to open a Windows command prompt in the directory with the program to run it.
It will need a network to work and networks can be found on the server.
But you can immediately launch, to see the options:
sai.exe --helpIf you'd rather play with a strong SAI 9x9 network, we provide a compiled 9x9 executable sai9x9.exe but you can also simply run sai9x9.bat and you will play agains the S1 network from the 9x9 paper, which is included inside the zip file.
The steps to run SAI are same as above.
