jev current - Vainona

Conformance run pending. This version becomes active, and GET /engines lists it, once it passes the conformance suite.

Use this version with "engine": {"name": "jev", "version": "current"}. current runs whichever Jev version the provider serves. Every answer records the epoch of model behaviour that produced it; a new epoch begins only when we detect a change, and then we re-check quality against the conformance suite.

Data handling


Hosted by	TypeSafe AI, in the US
Region	us
Subprocessor	TypeSafe AI operates the model. The full list of subprocessors is in the data processing agreement.
Customer data	The compiled context is sent to the engine provider’s API with zero data retention requested on every call.
Version retirement	Version `current` is not pinned: it is whatever model the provider serves now, and that can change without notice. Every answer records the epoch of model behaviour that produced it: `engine_version` is `current+` the date the epoch began and its number, such as `current+2026-09-24.1`, or `current+pending` in the first minutes after a new deployment. A new epoch begins only when we detect a change. The model’s answers vary slightly between identical calls, so we probe it every 30 seconds and compare 10-minute averages; when its behaviour changes we start a new epoch, with the next number, and every answer from then on records it. Answers already computed keep the epoch they were computed under. `current` itself is never retired: a change of model starts a new epoch instead. If the provider stopped serving Jev altogether, judgments on it would fail with `engine_version_unavailable`; we never re-pin a judgment silently.

Conformance

No conformance run is recorded for this version yet. Every version passes the same suite before it becomes active: 500 human-labelled items per type from a fixed golden set that no engine is tuned to. This page shows the results, with the date and the golden set version, once the run exists.
