Toby Ord: Logistic Benchmark Growth Means Success Odds Rise Exponentially Over Time

tobyordoxford · x · 2026-11-14

Toby Ord offers a mathematical observation in a discussion of AI capability trends: when the probability of success on a benchmark grows logistically over time, expressing it in odds means the odds rise exponentially. So, like task horizons, the odds of success on a random benchmark task are empirically observed to be improving exponentially with time — the logistic S-curve becomes a clean exponential line in odds space.
