How to read it
Each ball is a simulated buying scenario. Each row of pins is an AI model, pushing the ball toward the brand it picked.
One drop is one sample. Drop again and the pile shifts; the orange band shows where the balance lands in 95% of drops.
A leader is named only when the band clears the middle. The paths are simulated from the published per-judge shares: no model saw these scenarios.

How to read this
- Each scenario offers the models both brands; the split is how often each is chosen. The headline is the panel consensus with equal model weights.
- The band is the 95% interval for the left brand's share. A model leans to a brand only when its whole interval sits on one side of 50%.
- 95% confidence intervals (MOVER combination of the per-judge intervals, widened for small samples in battles and newer boards). The consensus gives equal weight to each model family. Per-judge results below are the primary measure.
- A single model's view is one judge, not the consensus.
- The drop machine is simulated: its paths reproduce the published per-model shares.
- Need cuts are withheld below 30 scenarios.
- Each page shows the latest edition. Dates are in the downloadable JSON.
- Fast panel: the fast or small current models of each vendor, not the full flagship panel.
Details and sources
Results computed but not published Only the overall consensus and per-judge results are published for this battle: each buyer need has fewer than 30 scenarios, the pre-registered minimum for a need row. See who was counted and why
Who was counted
The rule that decides which judges count was fixed before the run. Judges that met it are counted with the weights below; the others are listed with their reasons.
- 60 buyer scenarios were planned.
- None of them was left out.

Results computed but not published
Per-need scenario counts (n) are computed deterministically from the pre-registered plan.
- Buyer need: All-day athleisure and travel comfort
- n = 6 scenarios (fewer than 30) — Fewer scenarios than the pre-registered minimum
- Buyer need: Court sports and lateral movement
- n = 6 scenarios (fewer than 30) — Fewer scenarios than the pre-registered minimum
- Buyer need: High-intensity and interval training
- n = 6 scenarios (fewer than 30) — Fewer scenarios than the pre-registered minimum
- Buyer need: Hot-weather breathability outdoors
- n = 6 scenarios (fewer than 30) — Fewer scenarios than the pre-registered minimum
- Buyer need: Inclusive sizing and inseam options
- n = 6 scenarios (fewer than 30) — Fewer scenarios than the pre-registered minimum
- Buyer need: Outdoor running and layering
- n = 6 scenarios (fewer than 30) — Fewer scenarios than the pre-registered minimum
- Buyer need: Post-workout warm-up and recovery
- n = 6 scenarios (fewer than 30) — Fewer scenarios than the pre-registered minimum
- Buyer need: Strength training and gym durability
- n = 6 scenarios (fewer than 30) — Fewer scenarios than the pre-registered minimum
- Buyer need: Value multi-piece workout wardrobe
- n = 6 scenarios (fewer than 30) — Fewer scenarios than the pre-registered minimum
- Buyer need: Yoga, Pilates and studio stretch
- n = 6 scenarios (fewer than 30) — Fewer scenarios than the pre-registered minimum
Methodology
Each judge is an AI model called through an API; “About this result” names each model and how it was called. In each buyer scenario, the judge chooses between the two brands. The scenario is the unit of analysis.
The results are based on 60 buyer scenarios.
A judge leans to a brand only when its confidence interval excludes 50%. Point estimates alone never count as a win.
