GPT-5 FrontierMath performance
Epoch AI's grouped bar chart drew 60.9K views on X: 0.9x its typical post and #53 of 97 Epoch AI charts we track by views. Read Oct 10, 2026.
Let’s take a look into GPT-5’s record-setting performance on FrontierMath. How did it perform on the holdout vs. non-holdout set, how did it do across tiers, and what new Tier 4 problems did it solve? 🧵
Why it spread
This post spread because it landed on a hot topic that week and rode launch timing, reaching 60,936 views, 328 likes, 40 reposts, 8 quotes, and 59 saves, with likes running well above the account's typical 114.
What worked
- The post framed the chart around a record-setting performance on FrontierMath, which matched a hot topic that week and the launch timing of GPT-5.
- The grouped-bar chart broke the story into clear questions: holdout versus non-holdout, performance across tiers, and which new Tier 4 problems were solved.
- The post was branded, showed a source line, and came from an account whose source reach sits in the top quarter, which helped the chart travel.
What to borrow
We could take a timely launch or record moment and structure our own chart post as a short thread that answers a few concrete questions about our data, using a grouped bar to compare segments.
Careful
Do not over-read the spread as proof of chart quality alone, since the main reasons were a hot topic that week and launch timing, and the quote rate was below average.
