OpenAI posts Common Voice WER comparison bar chart

The December 15, 2025 bar chart drew 227K views and a 0.54% engagement rate, with saves at 1.6x the AI chart median.

What happened

OpenAI published a bar chart on December 15, 2025 comparing WER for gpt-4o-mini-tts models, one of 3 charts in the post. It was the account's only post that day.

The numbers

The post reached 227K views, #241 of 1,162 AI chart posts, against a 39.9K median among AI chart posts. Its score of 71 ranks #200 of 1,162 AI chart posts and #13 of 74 OpenAI posts.

The lesson

A 0.12% save rate, 1.6x the AI chart median, shows readers kept this bar chart even as its 0.54% engagement rate sat below the median. The 3 charts in the post share its numbers, so the save rate is the post's, not one chart's.

What it means

At #13 of 74 OpenAI posts, this chart sits well inside the account's own range, while its 0.12% save rate runs 1.6x the AI chart median. The 227K views against a 39.9K median show reach and saves moving apart.
