Model versions

A dated identity for the model package that produced a specific forecast record.

In plain language

A model version helps distinguish one issued forecast from another. A newer version may use updated inputs or implementation, but newer does not automatically mean more accurate.

What to check

  • Keep the issued date and model version together when comparing forecasts.
  • A historical or archived estimate is not the current model release.
  • Forecasts remain uncertain regardless of their model version.
