Every score this model has on the boards we track, one board at a time. Nothing is averaged across boards.

Scores on each board

Each rank is the board’s own: the rank it publishes, or the model’s place in the board’s own order where it publishes none. The bar shows how much of that board the model ranks ahead of. Scores from different boards cannot be compared.

The same model at each effort setting. A bar runs from zero to that board’s best score, so read each board on its own and never across boards.

Value: where it sits on the kill line

Each dot is a model: further right costs more, higher up scores more. Where the dashed lines cross stands the executioner, the best value on the board. Everything below and to its right costs more and scores no higher, so it is killed. Above the line is SOTA, the top tier; below and to the left is cheaper and weaker, the low-cost picks.
