14 measured metrics · 1 study
OpenRoutervsAnthropic
No row separates them: 14 ties.
The verdict
OpenRouter and Anthropic share 14 reported list prices from one study. No row names a winner: a reported list price has no interval, so each gap is stated, not ranked. Prices change often; the snapshot date is in each row’s context. The rows are 14 ties; each row says why.
Headline metrics
How far apart the two sides are on the headline metrics. Length is the ratio of the two values; it is not a winner.
Bar length is the ratio of the two values on a log scale, pointing to the larger one. Larger is not better for time, tokens or cost. A bar has a side’s color only when that side is ahead in the data; gray means the data does not separate them.

n is shown per side on every row
6 headline metrics as the ratio of the two values. None of them separates the sides in the data.
Metric by metric
Both values of a row come from the same chart in the same study. Each row has its own axis. The shaded band is where the two intervals or ranges overlap: a side is ahead only when they do not.

When to pick which
Only from the rows above. A tie is not a reason to pick either side.
When to pick OpenRouter
No row in this data puts OpenRouter ahead of Anthropic. Pick on other grounds (price, access, the tasks you run), or measure your own workload.

How a row is called
- AheadThe 95% intervals do not overlap, or the run ranges or p50–p95 bands do not overlap with at least 5 runs per side.
- TieThe values match, or both sit at the same ceiling.
- UnclearThe intervals or ranges overlap, too few runs were recorded, no interval was recorded, or more is not better (token counts are never a win).
- CalculationDerived from list prices and recorded counts. Not a bill and not a run.
The dataset compiler makes every call; this page only draws it. No composite score, no rank.
Questions
- Which is better, OpenRouter or Anthropic?
- OpenRouter and Anthropic share 14 reported list prices from one study. No row names a winner: a reported list price has no interval, so each gap is stated, not ranked. Prices change often; the snapshot date is in each row’s context. The rows are 14 ties; each row says why.
- How were OpenRouter and Anthropic measured?
- They share 14 measured metrics from 1 public study: Inference provider index: 27 models, 52 providers. Every row names its configuration, its sample size and its interval or range.
