Judges page

A judge scores the runs of other agents. You’ll come to the Judges page to register a judge or to open one that exists.

Each judge appears as a card with its status, name, and description, and View details opens its Judge page. Judges are grouped by team the same way agents are. In the sidebar, the Judges item expands to list judges without a team first, then a heading for each team with that team’s judges under it. A team heading filters the page to that team.

Register judge opens a form with a name, an optional description, a team, and an owner. Judges take no risk profile. The button is unavailable until your account has an LLM provider with at least one model, and a note above the list links to account settings to add one. After you register a judge, Prefactor opens it on its Configuration tab with the Create judge dialog already open, because a hosted judge cannot score anything until it has a version.

Judges registered here are hosted: Prefactor runs them on a model from one of your LLM providers. A remote judge, whose logic runs in your own infrastructure, is registered from the CLI or the API with its execution mode set to remote; see Run a remote judge.
