Across the 20 numeric entries in this window the median is 88.9 and the mean is 86.4, so the typical entry sits 0.00 below the leader. The window spans 83.3 to 88.9.
11 of 20 entries are at or above the median, and the top three hold 15% of the combined value — read it against the metric below, since a higher number is not "better" for every dataset.
5 creators appear in this window; the three most-represented hold 80% of the entries.
| Creator | Entries | Highest value | Top entry |

This ranking carries the metric
opennessIndex from the
Artificial Analysis Openness Index: Score dataset in the tab::eval-openness family. Units and the
direction of "better" are not declared by the source dataset, so AI Battle does not invent
them: values are shown exactly as published, and the ordering is the source dataset's own.
Rebuilt on from the
public dataset Artificial Analysis Openness Index: Score (family tab::eval-openness).
The source lists 20 entries and all 20 are shown here. AI Battle requests
the dataset's rows, keeps the ordering the source publishes, and computes only the statistics
on this page: median, mean, spread, the #1–#2 gap, the creator breakdown and the raw-data file.
Nothing on this page is generated text about the entries — the numbers come from the source.
Refresh cadence: every deploy re-pulls the dataset, so this page tracks the source's own update cycle. Corrections: see the methodology page.

K2 Think V2 by MBZUAI Institute of Foundation Models currently leads the Artificial Analysis Openness Index: Score ranking with a score of 88.9, the highest value in this dataset across eval openness. AI Battle aggregates the dataset from its public source and re-checks it daily.
The Artificial Analysis Openness Index: Score ranking is rebuilt daily from the upstream public dataset. Scores are the source dataset's own published values, so positions track whatever that source last released — each ranking page names the dataset it comes from.
The top 3 are: 1. K2 Think V2 (88.9), 2. K2-V2 (high) (88.9), 3. K2-V2 (medium) (88.9).
