What does it take to train cutting-edge AI?

Posted on X by @EpochAIResearch (Epoch AI), Sep 13, 2025. Source: x.com · See its data

Why it spread

It spread because a top quarter source reach met a self explaining chart about the largest training run to date, drawing 69,934 views, 194 likes, 35 reposts, 12 quotes, and 74 saves.

What worked

  • The post frames a concrete question about what it takes to train cutting edge AI and answers it with Grok 4, the largest training run to date.
  • The chart compares training Grok 4 against common benchmarks in cost, energy, water, and emissions, so it explains itself without extra reading.
  • It is branded, carries a source line, and comes from an account in the top quarter for source reach and quote rate, which helped it travel.

What to borrow

We could take one notable run or model of our own and compare it against familiar benchmarks across several resource measures, with a clear source line and a question led opening.

Careful

Do not over read the quote rate or reach as proof of chart quality, and do not copy the benchmark bar form if our data cannot support a like for like comparison.
