Model harness success rates
Social Capital's dumbbell chart drew 193.3K views on X: 1.1x its typical post and #21 of 41 Social Capital charts we track by views. Read Oct 14, 2026.
Model Benchmarks Are Worthless
Why it spread
The post spread mainly because it drew many quotes and used an unusual chart type, even though it earned 213 likes against the account's typical 1,082, only 0.2 times normal, and 8 reposts, 12 quotes, 53 saves and 38,529 views.
What worked
- The framing is a sharp question: how can a model score 24% and 59% on the same 113 coding tasks?
- The chart type is a dumbbell, which is unusual and helps the post stand out.
- The post is branded calibri and includes a source line, and the source reach sits in the top quarter.
What to borrow
We could use a dumbbell chart to show how one choice changes outcomes across the same set of tasks, and open with a plain question that names the two numbers.
Careful
Do not over-read the likes, since 213 is only 0.2 times the account's normal 1,082, and do not treat the quote rate as proof of broad agreement.
