Typed decisions on CPU, in milliseconds - Jev-compatible, plugin-routed, open.

Sabaki routes an unstructured state to the right tiny classifier and returns a typed answer (choice / score / noul) with calibrated confidence - over an HTTP API that speaks the System One contract. No GPU, no API key, no per-call cost.

import { Sabaki } from "sabaki";
import mail from "@sabaki-js/mail";

const sabaki = new Sabaki().register(mail).setFallback(generalist);
await sabaki.decideAsync({ state: "Invoice charged twice, need a refund", question: "bucket" });
// { decision: "billing", confidence: 0.89, domain: "mail", plugin: "@sabaki-js/mail" }

Live: https://sabaki.fox3000foxy.com/v1/systemone - or self-host in one line: await sabaki.serve({ port: 8000 }). See the GUIDE.

Specialists answer their trained questions; the generalist answers anything (instructions + criteria, truly read by the model). The model field always names the actual responder.

* the served generalist (mini, 22.7M) scores 0.536 on the typed-decisions test split (vs 0.29 for v4) plus phishing recall 0.616 on 2,000 held-out emails — measured, preliminary, improving.

* own split per run (not comparable across rows). PhishNChips (2,000 held-out emails) and the typed-decisions test split are identical for every row. †n=200 subset.

sabaki generalist is 22.7M — about 6.5× smaller than the smallest model below, and the smallest general-purpose decision model in this list (Cua-S1's 706K scorer is smaller but form-specific). Figures below are self-reported by their authors unless noted; protocols and splits differ.

A few points less for 1000× lower latency: nano ~18 000 req/s, mini ~71 req/s (1 thread) - a 35 Hz game tick fits on any CPU. See @sabaki-js/doom: the same stack exits MAP01 end-to-end (video in repo).
