AI model task length
METR's scatter plot drew 88.7K views on X: 0.6x its typical post and #20 of 26 METR charts we track by views. Read Oct 10, 2026.
We estimate that Claude Opus 4.1 has a 50%-time-horizon of around 1 hr 45 min (95% confidence interval of 50 to 195 minutes) on our agentic multi-step software engineering tasks. This estimate is lower than the current highest time-horizon
Why it spread
This post spread because it put a hot topic that week into a single self-explaining number, drawing 88,680 views, 296 likes, 27 reposts, 14 quotes and 78 saves, even though the account's typical likes are 523.
What worked
- The post explains itself: the text states the estimate, the confidence interval and the comparison to the highest point estimate, so the chart needs no extra context.
- It rides a hot topic that week, and the account is branded with a source line, which together with a top quarter source reach and a top quarter quote rate helped it travel.
- The framing is a simple scatter showing AI model task length growing exponentially over time, with high self-labelling and low unusual form, so the message lands fast.
What to borrow
We could take one headline estimate from our own data, state it plainly with its uncertainty and its comparison point, and let a simple scatter carry the exponential trend.
Careful
Do not over-read the likes as a win against the account's typical likes of 523, and do not copy the low comment and points fields as if they were measured here.
