Muse Spark benchmark performance
Epoch AI's benchmark bar chart drew 87.6K views on X: 1.3x its typical post and #40 of 97 Epoch AI charts we track by views. Read Oct 10, 2026.
We had pre-release access to Meta’s new Muse Spark model and evaluated it on FrontierMath. It scored 39% on Tiers 1-3 and 15% on Tier 4. This is competitive with several recent frontier models, though behind GPT-5.4.
Why it spread
It spread because it landed on a hot topic that week and rode launch timing, with 87,566 views, 370 likes, 40 reposts, 8 quotes and 47 saves, well above the account's typical 114 likes.
What worked
- Pre-release access to Meta's new Muse Spark model gave the post a genuine news hook, and the benchmark bars made the tier comparison easy to read at a glance.
- The framing was competitive but honest, noting the model was behind GPT-5.4, which kept the claim credible rather than overhyped.
- The chart was branded and carried a source line, and the account's reach sits in the top quarter, so the post reached an audience already primed for frontier model news.
What to borrow
We can pair our own charts with a timely launch or news moment, show a clear tiered benchmark comparison, and state plainly where our result stands relative to a named leader.
Careful
Do not over-read the quote rate, which was below average, and do not assume the numbers came from the chart design alone; the hot topic and launch timing did much of the work.
