What is Judgment Labs?
Judgment is built for agents whose runs are long rather than short, where a single task can span hundreds of steps and the stored trace runs to a very large amount of text. Storage and indexing are shaped around that, so a billion tokens of agent data stay searchable. Background agents read the stored runs and report the failure patterns nobody was looking for, with findings written in plain terms, for example a repeated lookup after an empty result, a confirmation sent before the step that justifies it returned, or a case that should have been escalated. The open-source judgeval SDK is Apache 2.0. Billing runs on monthly credits against data ingested and evaluator runs.
