Why it spread
This chart post spread because it landed at launch timing from an independent author, and the measured numbers show 82,022 views, 228 likes, 23 reposts, 10 quotes, and 41 saves, with likes well above the account's typical 114.
What worked
- The post pairs a clear benchmark-bars chart showing Kimi K2.5 leading open-weight models in ECI score with a plain framing that its score of 147 is about on par with o3, Grok 4, and Sonnet 4.5.
- It carries a branded look with a source line, medium design polish, and medium self-labelling, which makes the chart easy to trust and share.
- The launch timing and independent author status drove an above average quote rate and top quarter source reach, turning a niche benchmark result into a widely seen post.
What to borrow
We could reuse the benchmark-bars form and the on par with named rivals framing for our own model comparisons, keeping a source line and a clear note on where our result still lags the frontier.
Careful
Do not over-read the 228 likes, 23 reposts, 10 quotes, 41 saves, or 82,022 views as proof that the chart design alone caused the spread, since launch timing and independent author status were the main reasons.
