What is Jev AI?

Jev AI is TypeSafe's structured decision model for applications that need fast, typed answers such as a selected category, a numeric score, or a yes-or-no judgment. It is built for product logic, routing, scoring, and classification rather than long-form text generation.

Jev AI Guides collects beginner explanations, API patterns, integration notes, model comparisons, and practical use cases in one tutorial hub for builders who want to understand where Jev AI fits inside real software workflows.

Jev AI Beginner Guide

Start here if you want the clean mental model: Jev AI handles bounded decisions, while generative models handle writing and open-ended reasoning.

1Learn the difference between structured decisions and free-form generation.
2Identify the state your application can safely send into a decision call.
3Choose a narrow question your code can act on immediately.
4Route the typed result into product logic, review queues, or analytics.
Read Full Guide

Jev AI API Quickstart

Follow a practical setup path for turning a product decision into a Jev AI request and reading the response in application code.

1Define the user input, event, document, ticket, or agent state to evaluate.
2Select the primitive that matches the output your application expects.
3Send the request through the TypeSafe API or supported provider route.
4Use the returned decision as a typed signal in your workflow.

Jev AI Decision Primitives

Understand the three core Jev AI primitives and the product situations where each one makes sense.

ChoicePick one option from a defined set such as ticket type, next tool, or moderation category.
ScoreRate an ordered scale such as urgency, quality, intent strength, or customer sentiment.
NoulAnswer a bounded yes-or-no question for filters, gates, checks, and simple classifiers.
BatchAsk several related decisions over the same input so the workflow can branch cleanly.

Jev AI Agent Routing

Use Jev AI as a fast decision layer inside agents where each step needs a bounded routing or evaluation choice.

1List the allowed tools, actions, or branches before the agent asks for a decision.
2Send compact state instead of a full conversation whenever the decision is local.
3Route to the selected tool, category, review path, or stop condition.
4Keep permissions, payments, deletion, and account changes behind application rules.
