What it does

Jev is TypeSafe’s model for structured judgments inside software. Applications submit a state and a set of questions, then receive typed answers rather than generated prose. Choice questions select an option, Score questions evaluate a rubric and Noul questions return a value for whether a statement holds; the returned probability and confidence fields depend on the question type.

Developers can call Jev through an API, supported SDKs or a browser playground, and an agent skill helps coding assistants build an integration. The model is intended for narrow decisions that software can combine through explicit logic. Break broad judgments into well-scoped questions and decide in code when uncertainty requires review. Current pricing and allowances were not established from the reviewed public documentation, so check the console before committing to a workload.

What it can do

  • Typed choice judgments

  • Developer SDKs
  • Browser playground

Before you choose

  • Confidence is returned for some question types, not every answer.
  • Calibrated probabilities still require task-specific evaluation and decision thresholds.
  • Public recurring or usage prices were not confirmed.
