Real-world results are in for Claude Haiku 5.5 (High) by @AnthropicAI.
Why it spread
This post spread because it landed at launch timing for Claude Haiku 5.5 with an unusual chart type, a scatter plot showing score per dollar, and it earned 430 likes against the account's typical 20, which is 21.5 times normal, plus 39,195 views, 56 saves, 14 reposts and no quotes.
What worked
- The scatter chart made a cost efficiency story visual by showing Claude Haiku 5.5 leading in score per dollar, which is a more unusual form than the account's usual output.
- The post tied the chart to a live launch moment, debuting at number 30 with 1587 pts in Code Arena: WebDev and sitting just outside the Pareto frontier.
- The branded framing and concrete price comparison, matching GPT-6 Luna at $0.10/$0.50 per 1M input/output tokens, gave the chart a clear reason to save and share.
What to borrow
We could take our own benchmark data and plot score against price as a scatter to show which of our models leads in score per dollar, then publish it on the day a new model or version launches.
Careful
Do not over-read the spread as proof that the chart design alone drove it, since launch timing and the account's existing reach are listed as main reasons, and the source line is absent with source reach and quote rate both in the bottom quarter.
