Is Jev 1.13 going away?

TypeSafe has said 1.13 remains available for a while with deprecation notice before removal. Optio keeps this page even while the default upstream points at 1.14.

Should new projects start on 1.13?

No — start on Jev 1.14 unless you have a hard pin. Use this page when you must match an existing 1.13.0 log line or compare versions.

Does 1.13 support Box or images?

Not on the path documented here. Experimental image input and Box questions are called out on the Jev 1.14 landing.

Is Optio the official TypeSafe site?

No. Optio is an independent gateway for calling Jev and is not affiliated with, endorsed by, or an official product of TypeSafe.

Jev 1.13 — the previous stable System One decision model

Jev 1.13 (jev-1.13.0) remains documented here for version pinning and migration. Optio's default upstream is now Jev 1.14 (typesafe/jev-1.14.0). Same $0.042/M input pricing family, text Noul/Choice/Score, no experimental Box or image path on this page.

What 1.13 is

Jev 1.13 is TypeSafe's prior official System One release: typed Noul, Choice and Score questions over a text or JSON state, returning calibrated probabilities and confidence. It is the version many existing integrations logged as jev-1.13.0 before 1.14 shipped.

How it sits next to 1.14

1.14 keeps the same core question types and list price ($0.042 per million input tokens, output free) and adds experimental image input and Box questions, plus TypeSafe's 262K long-context danger zone. Prefer /models/jev-1-14 when you want those capabilities; stay on this page when you are documenting or comparing a 1.13 pin.

Calling through Optio

Optio's hosted default now targets typesafe/jev-1.14.0. This landing stays so search and bookmarks for 1.13 do not 404, and so migration notes have a stable URL. Re-run your ten calibration cases before moving confidence thresholds from 1.13 to 1.14.
