Price per unit of capability (cheapest METR-hour on OpenRouter)
1What this measures
For each price date, the lowest OpenRouter prompt price (USD per million tokens) divided by the model's latest METR 50% time horizon in hours, across models present in both datasets. Derived metric frontier_price_per_horizon_hour.
Why it matters. Price per unit of capability is the lab layer's capture proxy. Falling means the surplus from better models is passed to applications and users; flat or rising means labs keep it.

2How we track this
- derived metric
frontier_price_per_horizon_hour(formula in the semantic layer)
Direction over 4 periods, dead-band $0.02; higher = concentrating.
Four price change-points; a move under two cents per million tokens per horizon-hour is noise. Rising = labs keeping the surplus from capability gains.
Applied to metric:frontier_price_per_horizon_hour.
3Tracker interpretation
The series records price change-points from 10 September 2026; a direction needs several months of them.
4Evidence
Direction over the last 4 periods; the band is ±$0.02 around the window's first point. Higher reads concentrating.
32 observations. Hollow points are disputed (see counterevidence). Every point links to its observation.

5Status and reasoning
First price snapshot, 10 Sep 2026: the cheapest METR-measured capability on OpenRouter costs about $0.30 per million prompt tokens per hour of 50% time horizon (16 models present in both datasets). The series records price change-points, so a direction needs four more of them; not yet measurable until then. Initial seed.

What cuts against this reading
One router's list prices, prompt tokens only; METR's horizon is software tasks under its suite, not general capability; the cheapest model per horizon-hour is a moving target as models are added.

9Confidence
40 / 95 — limited or vague evidence
Confidence is independent of status: 90–95 multiple strong independent sources; 70–89 good evidence, some ambiguity; 50–69 mixed or hard to operationalise; below 50 limited or vague.
