Typesafe.ai System One Model Jev navigating a Neo4j graph by using a classifier over neighbouring relationships

What it is
A demo application that navigates a Neo4j graph one hop at a time using TypeSafe's (typesafe-sdk) systemone structured-decision API instead of free-text LLM generation. At each visited node, the outgoing relationships are presented as Choice options (relationship type, relationship properties, target node label/properties), and the API returns a full probability distribution over which relationshi
Where the decision sits
neo4jev 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 2026-09-16, last pushed 2026-09-18, 47 stars and 5 forks when we read it on 2026-09-20. 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.
What we have not checked
Whether it works. We have not run this project, measured the model behind it, or verified any performance claim in its README. This page records what the repository says about itself, read on 2026-09-20. The one model we have measured end to end is Jev.
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.
