There's no comparison to prior full-press Diplomacy agents, but if I'm reading the prior-work cites right, this is because basically none of them work - not only do they not beat humans, they apparently don't even always improve over themselves playing the game as if it was no-press Diplomacy (ie not using dialogue at all). That gives an idea how big a jump this is for full-press Diplomacy.

Author Adam Lerer on speed of progress:

> In 2019 Noam Brown and I decided to tackle Diplomacy because it was the hardest game for AI we could think of and went beyond moving pieces on a board to cooperating with people through language. We thought human-level play was a decade away.
