@ArtificialAnlys posts AI omniscience index and accuracy bar chart

A 30-model bar chart on the AA-Omniscence Index drew 1.6K views and a 1.18% engagement rate, below the AI chart median for views.

What happened

@ArtificialAnlys published a bar chart on the AI omniscience index and accuracy on September 22, 2026. It was one of 9 posts from this account that day, alongside posts on the Artificial Analysis Intelligence Index vs Cost and the Artificial Analysis Intelligence Index v4.3.

The numbers

The post reached 1.6K views, ranking #1,101 of 1,162 AI chart posts and #447 of 491 @ArtificialAnlys posts. Its score of 23 ranked #1,037 of 1,162 AI chart posts.

The lesson

A 30-model bar chart drew 1.6K views against a 39.9K median among AI chart posts. The 1.18% engagement rate cleared the median while views did not, so the save and like rates carried the score.

What it means

At #398 of 491 @ArtificialAnlys posts by score, this chart sits below the account's own median. The 0.14x gap to the company median views shows the reach shortfall against @ArtificialAnlys's typical post.
