Understand Jev (the only video you need)

ZazenCodes demonstrates how to query TypeSafe's Jev model using the Python SDK. The tutorial covers Jev's core decision primitives—Noul, Choice, and Score—along with parallel multi-question evaluation and an automated support ticket triage loop.

What you’ll find in the video

  1. Jev is a non-generative, System 1 decision model that enforces schema adherence across core primitives like Noul, categorical choices, and ordinal scores.
  2. Multiple questions of differing types can be evaluated against input state in a single parallel call, returning probability distributions.
  3. Autonomous triage workflows can use Jev's output confidence scores to trigger deterministic actions or escalate low-confidence cases to reasoning agents.
Worth knowing

Auto-generated English captions reviewed with Gemini. The triage loop uses mock actions rather than live production integrations, and Jev lacks built-in web search, meaning out-of-the-box knowledge is constrained by its training cutoffs.
