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.

@arena posts Frontend Code Arena leaderboard with Kimi-K3 on top

What happened

@arena posted a Frontend Code Arena Ranking leaderboard on July 16, 2026. The same day the account posted Terrific Text Arena: Kimi-K3 Ranked #9, which drew 90.2K views.

The numbers

The post reached 20.1M views, #5 of 1,162 AI chart posts, against a 39.9K median among AI chart posts. Its score of 73 ranks #158 of 1,162 AI chart posts and #15 of 239 @arena posts.

The lesson

A leaderboard with 18 models shown drew 20.1M views but a 0.039% save rate: the chart travelled far while few readers kept it. The 0.17% engagement rate sits at the 4th percentile among AI chart posts.

What it means

At #15 of 239 @arena posts by score, this chart sits below the account's own top posts despite its #1 of 239 @arena posts by views. The 0.23x gap to the AI chart median engagement rate is where the score gives way.
