🚨🚨ALERT: ANTHROPIC IS A/B TESTING USAGE LIMITS
Why it spread
It spread because the post explains itself and comes from a big source: the account has 1,214 likes against a typical 148, with 85,589 views, 73 reposts, 34 quotes and 208 saves, and the quote rate is above average.
What worked
- The post text states the finding plainly and labels it as consequence, so readers grasp the A/B test without needing the chart explained.
- The grouped-bar chart shows the trade between monthly API value and 5 hour usage limits, which matches the two-part claim in the post.
- The account is a big source with top quarter source reach, and the post carries a source line and branding, which supports trust.
What to borrow
We can pair a grouped-bar chart with a short plain-language headline that names the tradeoff, and add a source line and our own branding so the chart explains itself.
Careful
Do not over-read the engagement as proof the chart design alone drove it, since the big source and the alert framing likely carried much of the spread, and do not copy the alarm tone without the same evidence.

We have not read this chart's numbers yet
Its own maker appears here once its numbers are read. Until then, these are other real charts in a similar format: each data page starts from that chart's numbers and takes yours.
API
Not in the API yet
We have not read this chart's numbers yet, so the API has nothing to return for it. Charts with numbers read are on the data page, and each one can be called by id.
