Top-5 card

Ordered by rank. Ranks are ranges: 2–4 means we can't statistically separate it from the models in that range (paired test on the same tasks; the chance of any false win on the board is at most 5%). The bar under each rank shows where its range sits.

Better and cheaper, or it doesn't count

Model M · low effort dominates 7 of 13 models on Navigator Bench — higher Index, lower cost per successful task.

A kill needs both: significantly better on the Index (a paired test on the same tasks, with the chance of any false win on the board held to 5%) and cheaper per successful task. A gap inside the noise never counts. How dominance is decided

Bars are the Navigator Index score on a plain 0–100 scale; the tick is your bar, and the number beside each bar is the score itself. Monthly cost = cost per successful task × successful tasks, printed as a number. Failed runs are already priced in: cost per success divides everything spent by the tasks that passed. Definition

Demo data · not real results This board is built from development fixtures, not from a published cycle. Model names are placeholders and no number on it is a measurement.

Navigator Index
0–100. The weighted mean of 8 category scores; a category score is the mean task score (partial credit, 0–1) × 100 over that category’s active tasks and every repeat. Weights: Coding 15% · Data analysis 15% · Extraction 10% · Reasoning 15% · Research & agentic 15% · Summarization 10% · Support 10% · Writing 10%. Research & agentic: For now these are single-call multi-step tasks: one model call returns plan → steps → deliverable, checked step by step. Tool-using, browsing and long agentic tasks are deferred.
Intervals
95%, task-clustered: a bootstrap over tasks (stratified by category for the Index), never naive per-run intervals. Every score on this page shows its interval as a whisker or a range.
Ranks are ranges
Every pair of models is compared on the same tasks (a paired test of the Index difference, with family-wise error control, so the chance of any false “win” on the board is at most 5%). A rank is the range the data allows: best = 1 + models significantly better, worst = N − models significantly worse. “2–4” means we can't statistically separate it from the models in that range; a single number means it is pinned down.
Dominance (kill zone)
A model dominates another only when it is significantly better on the Index (the same paired test) and has a lower cost per successful task. A point-estimate gap inside the noise is never a kill. Reference rows are never counted.
Cost per successful task
Everything measured on candidate calls (OpenRouter's reported amounts) divided by the tasks passed, where a pass is a score at or above the task's threshold. Judge cost is excluded. Blank when nothing passed.
Latency
Median wall-clock latency per run, as measured on the pinned provider.
Movement
Δ compares with the previous published cycle at the same Index version only. Without one, the entry shows NEW or “first cycle”; movement is never estimated.
Commoditization curve
One point per published cycle: the cheapest cost per successful task among models at Index 70 or better. With fewer than three cycles it reads “tracking since”.
Frontier and quadrants
The frontier joins models that no other model beats on both Index and cost per success. Quadrants split at the quality bar (Index 70) and at the median plotted cost per success; they are reading aids, not verdicts.
