- Frozen
- Retired versions keep their scores forever. A score is a statement about one model at one point in time, so it is never rewritten to match a newer release.
- Pricing
- Per-million rates come from the provider, but the cost shown on an entry is computed from the tokens its run actually consumed.
- Sweeps
- When a version ships, the registry reruns the top entries against it and publishes what moved in the changelog.
