A 15-model leaderboard post drew 1.4M views but a 0.18% engagement rate, landing in the Wide but thin quadrant.

What happened

The numbers

The post reached 1.4M views, #85 of 1,162 AI chart posts and #9 of 239 @arena posts. Its score of 66 ranks #321 of 1,162 AI chart posts.

The lesson

A 15-model leaderboard drew 1.4M views, 30x @arena's 46.2K median, yet its 0.18% engagement rate sits at 0.25x the 0.73% AI chart median. The chart travelled on views while saves and likes stayed at the bottom decile.

What it means

At #46 of 239 @arena posts by score, this leaderboard trails the account's own view rank of #9 of 239. The 1.4M views against a 0.18% engagement rate leave a wide but thin result for @arena's chart output.
