Jev · Yawn's reference model
What does TypeSafe say Jev does?
Provider description · reviewed 2026-09-23
TypeSafe describes Jev as a model for focused, typed judgments over text. Inputs may be text strings, objects or arrays; image, audio and video inputs are not supported in the reviewed documentation. The output is structured decisions and probabilities, rather than generated explanations.

Provider description · reviewed 2026-09-23
Choice returns an option, its option distribution and confidence. Score uses ordered levels and returns a score, level legend, distribution and confidence. Noul gives the probability of yes between zero and one; it has no separate confidence field. These are provider output contracts, not values observed in Yawn.

Provider description and documentation gap
TypeSafe describes Choice and Score confidence as a statistic derived from the distribution's concentration. The reviewed page does not specify its formula. Application thresholds depend on consequences and performance on the application's own examples; this reference adopts no numeric threshold.

Provider claim · local evidence unavailable
The provider describes calibration across groups of predictions and explicitly distinguishes it from an individual answer being correct. Yawn has no retained Jev evaluation population or outcomes in this reference, so its suitability for a Yawn decision remains unverified.

Yawn proposal · not implemented
Proposed contract: preserve the exact question and criteria, authorized source revisions, provider and model version, typed answer, full distribution when supplied, and any separate confidence statistic. Record human choices, corrections and outcomes independently. Test any decision threshold against relevant retained outcomes before adopting it.

No probability vector or provider confidence is reconstructed from a rank score or prose.
A later reference revision can correct this interpretation without rewriting the provider's historical response.

Cost not estimated.Is Jev connected or running here?
Integration unavailable
No. This is a public reference model. It has no provider credentials, live answer, calibration result or execution receipt. Inspecting it performs no Jev call and grants no model budget.
