Jev 1.14 from TypeSafe AI is now available on AI Gateway. Jev is a decision model for software. You pass it state and a set of questions, and it returns typed Choice, Score, and Boolean answers with probabilities instead of free-form text. It answers every question in one request, in parallel, for classification, routing, scoring, and automated verification.
Jev 1.14 accepts images as part of the state, and has an experimental long-context mode for documents, logs, or conversation histories that are too long for a standard request.
Use typesafe-ai/jev-1.14.0 as the model name.
Pass an image as a file part alongside text in state. This example reads a local PNG and asks a Boolean question about its color:
Enable long-context mode with providerOptions.typesafe.longContext: true. This example reads a support log and checks whether it reports a damaged delivery:
Jev supports Zero Data Retention and No Training, which you can enable per request. Decision calls also appear in logs and custom reporting, count toward budgets, and accept other Gateway provider options in the same providerOptions.gateway object.
