AI model task length scaling
METR's scatter plot drew 258.6K views on X: 1.7x its typical post and #9 of 26 METR charts we track by views. Read Oct 10, 2026.
We estimate that Gemini 3.1 Pro with thinking level `high` has a 50%-time-horizon of around 6.4 hrs (95% CI of 4 hrs to 12 hrs) on our suite of software tasks.
Why it spread
The post spread because it explained itself clearly and drew an unusually high rate of quotes, with 445 likes, 30 reposts, 22 quotes, 56 saves and 258,613 views, even though likes ran a bit below the account's typical 523.
What worked
- The post text states the headline finding directly, giving a 50%-time-horizon of around 6.4 hrs with a 95% CI of 4 hrs to 12 hrs, so readers did not need the chart to grasp the claim.
- The chart is a scatter that shows AI model task length growing exponentially over time, a simple and self-explanatory form with high self-labelling and low unusual form.
- It is branded and shows a source line, and it landed with top quarter source reach and a top quarter quote rate, which helped it travel beyond the account's usual audience.
What to borrow
We could pair a single plain-language headline number with a simple scatter of our own data, label it heavily, and add our brand and a source line so the chart stands alone when quoted.
Careful
Do not over-read the likes, since 445 is below the account's typical 523, and do not treat the quoted time horizon as precise given the wide 95% CI of 4 hrs to 12 hrs.
