Agent Pareto Frontier
Arena's line chart drew 35K views on X: 4.4x its typical post and #73 of 104 Arena charts we track by views. Read Oct 26, 2026.
GPT-6 Luna and GPT-6.1 Sol by @OpenAI now hold 6 of the 11 spots on the Agent Arena Pareto frontier across their reasoning efforts!
Why it spread
It spread because a polished, self-explaining chart from @arena reached 33,127 views and 349 likes, about 17.4x the account's normal response, with 30 reposts, 6 quotes and 50 saves.
What worked
- The design polish was high, so the chart looked credible and easy to share.
- The self-labelling was high, so the post explained itself without extra context.
- The framing was concrete: it named the models, the 6 of 11 frontier spots, the below $0.10/task range and the $0.22 to $0.65/task range.
What to borrow
We can use the same form by pairing a clean line chart of performance against cost with a short caption that states the exact ranges and counts, then labels the chart so it stands alone.
Careful
Do not over-read the spread as proof of broad debate: the quote rate was below average, and the post text was cut off, so the full message may not have travelled intact.
