@ArtificialAnlys scatter plot: AA-WER Streaming Index vs Time to First Partial

A scatter plot of 30 models on streaming transcription performance drew 1.3K views and a 1.06% engagement rate.

What happened

On September 18, 2026, @ArtificialAnlys posted a scatter plot of AA-WER Streaming Index vs Time to First Partial, showing 30 models. It was one of 10 posts from the account that day.

The numbers

The post reached 1.3K views, ranking #1,116 of 1,162 AI chart posts by views. Its score of 27 ranked #976 of 1,162 AI chart posts and #351 of 491 @ArtificialAnlys posts.

The lesson

A 30-model scatter plot drew a 1.06% engagement rate against a 0.15% save rate. The gap between engagement and saves shows readers interacted but did not keep the chart.

What it means

At #351 of 491 @ArtificialAnlys posts by score, this chart sits below the account's own median. The 0.12x gap to the account's 11.4K median views shows the scatter plot format drew less reach than the account's typical post.

On the Max plan you can pull this chart's numbers with the provenance of each one, as JSON or CSV, with its redraw spec, or call it from an agent over MCP. Chart id a55350d1d144.

Approximate values. Our two readings of this chart agreed only in part (confidence 0.30 of 1), so check the original before you quote a number. The API marks it lowConfidence, and ?min_confidence=0.5 leaves it out.
