AI model cost performance
Arena's scatter plot drew 40.5K views on X: 0.9x @arena's median post and #577 of 1,162 AI chart posts we hold by views. Read Oct 10, 2026.
Claude Sonnet 5.5 by @AnthropicAI just landed at #3 in the Agent Arena. This model has a median cost per task of $2.74, and a +12.5% net improvement score.
Why it spread
The post spread because it landed on a hot topic that week and explained itself clearly, driving 40,458 views, 331 likes, 17 reposts, 6 quotes, and 35 saves, which is 16.6x the account's typical likes of 20.
What worked
- The chart explains itself, so viewers could grasp the Pareto frontier claim without extra context.
- It rode a hot topic that week, which lifted a normally modest account to 16.6x its typical likes.
- It was branded and showed a source line, giving the claim credibility while the scatter form stayed familiar.
What to borrow
We could frame our own chart around a hot topic and make it self-explanatory, with a clear headline claim and a visible source line, so it travels on its own.
Careful
Do not over-read the spread as proof of design quality, since design polish was only medium, the quote rate was below average, and source reach sat in the bottom quarter.
