What it is
Write the decision once. Run it on any System One provider.
The homepage listed on the repository, iamaamir.github.io, puts it like this: A provider-neutral TypeScript runtime for System One decisions. Use TypeSafe Jev, Reflex, compatible /v1/systemone endpoints, or your own provider. Includes direct Pi integration.
Getting started
From the README:
npm install system-one-coreWhere the decision sits
system-one 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.
How active it is
Created 2026-09-22, last pushed 2026-10-08, 75 stars and 6 forks when we read it on 2026-11-02. Everything in this category is weeks old at most, so a stale push date means something different here than it would on a mature project. Check the repository before you depend on it.
Find out what your data actually supports
We turn your historical decisions into a frozen test set, then tell you which model, which threshold, and how much of it you can safely automate.
