What worked
- The post text leads with a clear point gain of 257 points, comparing 1587 points for Claude Haiku 5.5 against 1330 points for Haiku 4.5.
- The chart is branded and shows a source line, which supports credibility for a team that makes its own charts.
- The framing states improvement across all categories, giving the audience a simple takeaway beyond the single headline number.
What to borrow
We could use the same launch timing and unusual chart type by pairing a new release moment with a chart form we do not normally publish, while keeping a clear before and after point comparison and a visible source line.
Careful
Do not over-read the engagement: 0 reposts and 0 quotes with only 3 saves and 20 likes at 1.0x normal suggest the reach came from timing and form, not from exceptional sharing or discussion.
