AI benchmark progress
Epoch AI's line chart drew 151.7K views on X: 2.2x its typical post and #28 of 97 Epoch AI charts we track by views. Read Oct 10, 2026.
Has LLM progress slowed?
Why it spread
It spread because it answered a hot question that week about whether LLM progress has slowed, and it did so with a chart that explains itself, reaching 151,738 views, 507 likes, 80 reposts, 23 quotes and 128 saves.
What worked
- The post opens with a direct question, "Has LLM progress slowed?", which names the hot topic that week and gives people a reason to stop and read.
- The chart is a line chart that explains itself, with high self labelling and a source line shown, so viewers can grasp the GPT-5 versus GPT-4 story without extra context.
- It is branded and comes from an account whose source reach and quote rate both sit in the top quarter, so the framing carried weight and invited discussion.
What to borrow
We could take a live question our audience is already asking, answer it with one self explaining line chart, label the series clearly, show our source line, and keep the takeaway in the post text so the chart and caption reinforce each other.
Careful
Do not over read the raw totals as proof of quality, since views, likes, reposts, quotes and saves reflect a hot topic and a top quarter source reach, and the design polish is only medium with low unusual form, so the format itself is not the main driver.
