Benchmark bar chart of 12 models, posted September 3, 2026, with 4 other posts that day.

What happened

Published September 3, 2026, a single benchmark bar chart on the Coding Agent Index v1.4, showing 12 models. Same day, the account posted 4 other charts, including a 1.7M-view AI Coding Agent Index.

The numbers

Views reached 82.7K, ranking #420 of 1,162 AI chart posts. Engagement rate 0.88% ranks #411 of 1,162; save rate 0.071%.

The lesson

A 12-model benchmark bar chart drew 7.2x the account's median views. Clean tables with many models can outperform typical posts.

What it means
