@ArtificialAnlys posts AA-Briefcase and GDPval-AA v2 leaderboard chart

The benchmark bar chart drew 22.4K views and a 0.98% engagement rate, above the 0.73% median among AI chart posts.

What happened

@ArtificialAnlys published a benchmark bar chart on September 21, 2026, covering AA-Briefcase and GDPval-AA v2 Elo leaderboards. It was one of 8 posts from the account that day, alongside 7 others.

The numbers

It reached 22.4K views, ranking #696 of 1,162 AI chart posts by views and #200 of 491 @ArtificialAnlys posts. Its score rank is #691 of 1,162 AI chart posts.

The lesson

A single benchmark bar chart with 6 models shown drew a 0.98% engagement rate, 1.3x the 0.73% median among AI chart posts. The 0.054% save rate sits far below that engagement, so readers engaged without keeping the chart.

What it means

At #200 of 491 @ArtificialAnlys posts by views, this chart sits above the 11.4K company median at 22.4K. Its #696 of 1,162 rank among AI chart posts shows the reach stays below the 39.9K median for that peer group.
