@arena posts Pareto Frontier scatter for Text Arena

A 6-model scatter on September 26, 2026 drew 15.8K views and a 0.40% engagement rate, both below the AI chart medians.

What happened

@arena published a scatter plot on the Pareto Frontier for Text Arena on September 26, 2026. It was 1 of 2 posts from the account that day, alongside a Text Arena Leaderboard post at 265K views.

The numbers

It reached 15.8K views, #752 of 1,162 AI chart posts, against a 39.9K median among AI chart posts. Its score of 34 ranks #842 of 1,162 AI chart posts and #188 of 239 @arena posts.

The lesson

A 6-model scatter at 0.095% save rate and 0.40% engagement sits below the 0.73% AI chart median. The chart shows one printed value, claude-opus-5.5-high at 1509 Arena Score, so the plotted labels carry the post.

What it means

At #188 of 239 @arena posts by score, this scatter trails the account's own chart output. The 0.34x gap to @arena's 46.2K median views leaves the Pareto Frontier topic below the account's usual reach.
