Others are purely subjective, like LMArena, which really only measures the personality and style preferences of the masses at this point, because frontier LLM technical answers are too hard for the average person to judge.
Then there are some interesting one-off benchmarks, but they lack enough rigor, breadth, and samples to draw larger conclusions from.
So we designed our benchmark with 3 goals: objective measurements (individual submissions not dependent on a human or LLM judge), no known correct answer (so simulations can scale to much higher levels of intelligence), and enough variety over important aspects of intelligence. We do this by running multiple models in cooperative/competitive environments with very complex action spaces and objective scoring, where model performance is relative and affected by the actions of other participants.
And yeah, there are some interesting results when you have a more objective benchmark. It should raise eyebrows when every single sub-release of every company's model is better across the board than its predecessor -- that isn't reality.
but the fact that you cite your brief as your main argument is funny - you don't even have any inherently subjective numbers to justify what you believe, you only have "I don't believe".
