SwiftJev

What it is

SwiftJev is the TypeSafe Jev provider for SwiftDecision. It sends typed Noul, Choice, and Score prompts to the hosted System One API and returns validated probability distributions through SwiftDecision's DecisionBackend protocol.

Getting started

From the README:

import SwiftDecision
import SwiftJev
let backend = try SwiftJev.JevDecisionBackend()
let engine = DecisionEngine(backend: backend)

Where the decision sits

SwiftJev calls the hosted decision API rather than running its own weights. That keeps the project small and means its behaviour moves whenever the vendor ships a new model version. It also means an API key and a network round trip sit in the path of every decision.

Models it references: Jev, jev.
