@EpochAIResearch posts FrontierMath accuracy comparison chart

The FrontierMath accuracy comparison drew 220K views but an engagement rate of 0.32%, below the 0.73% median among AI chart posts.

What happened

@EpochAIResearch published a FrontierMath accuracy comparison bar chart on April 18, 2025, showing 7 models. It was one of 4 posts from the account that day, alongside MATH Level 5, GPQA Diamond, and OTIS Mock AIME comparisons.

The numbers

The post reached 220K views, ranking #247 of 1,162 AI chart posts by views and #2 of 59 @EpochAIResearch posts. Its score rank is #433 of 1,162 AI chart posts.

The lesson

A benchmark bar chart with 7 models drew 220K views, 42x the 5.3K median for @EpochAIResearch posts, but its 0.32% engagement rate is 0.43x the 0.73% median among AI chart posts. The chart type and model count did not translate into saves or replies at the median rate.

What it means

For @EpochAIResearch, this post ranks #2 of 59 @EpochAIResearch posts by views yet #1,041 of 1,162 AI chart posts by engagement, a gap between reach and interaction. The 0.32% engagement rate against the account's own 1.37% median shows the chart travelled widely but thin.
