Interestingly, Google seems to be shifting its internal naming from "AI" to "SI" as well. 

> "build_arena_andwise_si_comparison" is an internal string related to model comparison. 

Will this spread even further?

-  SpaceXSI
-  MSL
-  SSI

-  MAI > MSI?
-  OpenAI > OpenSI?
-  Apple Intelligence > ASI?
