A shaded cell is the best value in its row, and the bar shows the score out of 100. The line under the Index and each category is the 95% confidence interval, where two intervals overlap, the ordering is not something this measurement establishes. Cost is list price at the time of the run and is not part of the Index.
What this comparison does not tell you
- These scores describe performance on veterinary examination items. They are not a certification, and no result here licenses a model for clinical use.
- The Index weights categories for a general caseload. Every per-category score is published above so you can weigh them for yours instead, or compare on a single category using the control above.
- Cost and latency are measured at run time and move separately from the scores. A model that is cheaper today may not be next month.
