Each dot is a post. Right is more views, up is a higher engagement rate. The lines are the medians, so the four corners are the four kinds of post.

@ArtificialAnlys posts Artificial Analysis Intelligence Index v4.0 bar chart

A 20-model bar chart from @ArtificialAnlys drew 138K views but a 0.59% engagement rate.

What happened

@ArtificialAnlys published a bar chart on April 18, 2026, showing Artificial Analysis Intelligence Index v4.0 rankings. It was one of 4 posts from the account that day, alongside posts on AI Model Benchmarks Comparison, AA-Omniscence Index and Accuracy, and Artificial Analysis Intelligence vs Cost to Run.

The numbers

The post reached 138K views, ranking #328 of 1,162 AI chart posts by views and #67 of 491 @ArtificialAnlys posts. Its score of 65 ranked #344 of 1,162 AI chart posts and #102 of 491 @ArtificialAnlys posts.

The lesson

The chart shows 20 models in a single bar chart, and the post drew 138K views against a 39.9K median among AI chart posts. Its save rate of 0.10% sits below its 0.59% engagement rate, so the wide view count did not carry into saves.

What it means

At #102 of 491 @ArtificialAnlys posts by score, this chart post trails the account's own top tier despite 138K views. The 12x gap over the 11.4K company median views shows reach can arrive without a matching save rate.
