So who’s gonna win this one? AA Index or Vals Index?
Oh wait, who is user?
this tb4 story keeps getting wilder.
both vals ai and aa use mini-swe-agent harness, but the ranking is completely different:
vals ai:
opus 5.5 > sonnet 5.5 > kimi k3.1 pro > gemini 4 carbon
aa:
kimi k3.1 pro > gemini 4 carbon> sonnet 5.5 > opus 5.5
you can't make this up.
