How a debate runs.
A debate is 7 to 15 model calls: one per side each round, plus the judge. The setup shows the count before you start.
- 01
Set the motion
Write any claim. Pick the model that argues for it, the model that argues against, and the judge.
- 02
They argue in rounds
Choose 3, 5 or 7 rounds. Each round, both models answer the other side's last point, so the arguments sharpen instead of repeating.
- 03
The judge sums it up
When the last round ends, the judge lays out the strongest points on each side, the common ground and the real disagreements. The verdict is yours.
