GPT-4 model serving costs
Epoch AI's line chart drew 27.7K views on X: 0.4x its typical post and #76 of 97 Epoch AI charts we track by views. Read Oct 10, 2026.
Frontier language models used to grow larger every year. Since the release of GPT-4 in March 2023, they’ve instead been shrinking.
Why it spread
This post spread because it landed on a hot topic that week and benefited from launch timing, reaching 27,724 views, 181 likes, 20 reposts, 6 quotes and 70 saves, well above the account's typical 114 likes.
What worked
- The post text leads with a clear, surprising reversal: frontier language models used to grow larger every year, but since GPT-4 in March 2023 they have been shrinking.
- The chart is a simple line chart with medium design polish and medium self labelling, branded and showing a source line, which made the claim easy to trust and share.
- The post ties the chart to a longer explainer in the same week's Gradient Updates issue, giving readers a reason to save and follow up.
What to borrow
We could pair one of our own charts with a short, plain-language claim about a trend reversing, then link it to a fuller write-up so the chart acts as the hook and the article carries the detail.
Careful
Do not over-read the spread as proof the chart design alone drove it, since the facts point to a hot topic that week and launch timing, and the quote rate being above average does not tell us whether the quotes were positive.
