@ArtificialAnlys posts AI hallucination rate comparison bar chart

The bar chart shows hallucination rates across models, with printed values from 48% to 75%.

What happened

On November 17, 2025, @ArtificialAnlys published a bar chart on AI hallucination rates. It came with 3 other posts from the account that day.

The numbers

It reached 60.1K views, ranking #491 of 1,162 AI chart posts by views. Its score rank was #771 of 1,162 AI chart posts.

The lesson

A bar chart with 27 models shown drew 60.1K views but a 0.22% engagement rate, below the 0.73% median among AI chart posts. The 0.043% save rate trails the engagement, so the chart's size did not carry into saves.

What it means

For @ArtificialAnlys, this post's 60.1K views are 5.3x its 11.4K median, yet its 0.22% engagement rate is below the account's 0.82% median. The gap between views and engagement shows the chart travelled wide but thin.
