AI task length scaling

METR's scatter plot drew 141.6K views on X: 1.3x @metr_evals's median post and #326 of 1,162 AI chart posts we hold by views. Read Oct 10, 2026.

We estimate that Kimi K2 Thinking has a 50%-time-horizon of around 54 minutes (95% confidence interval of 25 to 100 minutes) on our agentic SWE tasks. Note that we conducted this evaluation through a third-party inference provider, which re

Why it spread

This post spread because it paired a hot topic that week with a chart that explains itself, reaching 141,614 views, 281 likes, 25 reposts, 12 quotes, and 44 saves, though likes stayed below the account's typical 523.

What worked

  • The post explains itself, so viewers could grasp the exponential growth of AI task time horizon with model release without extra context.
  • It rode a hot topic that week, which drove a quote rate above average and a source reach in the top quarter.
  • It was branded, showed a source line, and used high self labelling, which made the estimate easy to trust and share.

What to borrow

We could frame our own chart around a timely topic and let the chart explain itself, with clear self labelling and a visible source line, so the audience can read the trend without a long caption.

Careful

Do not over-read the like count as a win, since 281 likes came in below the account's typical 523, and do not treat the estimate as fully certain because it came through a third-party inference provider.

API · Max

Use this chart via API

On the Max plan you can pull this chart's numbers with the provenance of each one, as JSON or CSV, with its redraw spec, or call it from an agent over MCP. Chart id a5be200001c0.

Approximate values. Our two readings of this chart agreed only in part (confidence 0.43 of 1), so check the original before you quote a number. The API marks it lowConfidence, and ?min_confidence=0.5 leaves it out.
