Another rule bans "using third-party software or scripts in order to gain an unfair advantage over other players."

So is it even possible for O3 to beat another player while complying with the rules?

If a player uses such a model, the model is third-party and the player is cheating.

But: when a specific model is itself under test, I would say that during the test it becomes "first" (or second?) party rather than "third".

I think third-party here means not produced by GeoGuesser rather than not produced by the player.
