AI Word Error Rate
Artificial Analysis's bar chart drew 23.8K views on X: 0.4x its typical post and #100 of 123 Artificial Analysis charts we track by views. Read Oct 10, 2026.
StepFun has released StepAudio 3 ASR, ranking #1 on the AA-WER Index for non-streaming Speech to Text with 1.7% WER, a notable improvement on StepAudio 2.5 ASR (4.7%)
Why it spread
This chart post spread because it landed on a hot topic that week and rode launch timing, with the account getting 259 likes against its typical 16, plus 12 reposts, 1 quote, 66 saves and 23,788 views.
What worked
- The post pairs a clear ranking claim with a concrete measured improvement, going from 4.7% to 1.7% word error rate, which gives people a reason to share it.
- The chart is a simple bar form showing word error rate across transcription models, with medium design polish and medium self labelling, so it reads quickly.
- It is branded and shows a source line, and the source reach sits in the top quarter, which helped it travel beyond the account's usual audience.
What to borrow
We could take our own benchmark result and frame it the same way: one headline ranking, one before and after number, a simple bar chart, and a visible source line.
Careful
Do not over-read this as proofAndy that the format alone drives reach, since the main reasons given are a hot topic that week and launch timing, and the quote rate sits in the bottom quarter.
