@arena posts Agent Arena Spark 1.3 (Max) performance chart

A single benchmark bar chart for Muse Spark 1.3 (Max) drew 6.9K views and a 0.22% engagement rate.

What happened

@arena posted a benchmark bar chart on September 11, 2026, covering Agent Arena Spark 1.3 (Max) performance. The account posted 3 items that day, including posts on Agent Arena Spark 1.3 (Max) Ranked #13 and conceptual similarity to Claude.

The numbers

The post reached 6.9K views, ranking #881 of 1,162 AI chart posts and #201 of 239 @arena posts. Its score of 15 ranked #1,112 of 1,162 AI chart posts.

The lesson

A single-model benchmark bar chart at 6.9K views against a 39.9K median among AI chart posts shows the format's ceiling here. The 0.029% save rate sits below the 0.22% engagement rate, so saves are not carrying this chart.

What it means

At #233 of 239 @arena posts, this chart sits near the bottom of the account's own output. The 0.15x gap to @arena's 46.2K median views marks how far this post fell short of the publisher's typical reach.
