Jev Notes: A Handbook for Typed Decisions
An unofficial handbook for Jev AI, a decision-model API that returns typed probabilities, classifications, routing choices, and scores instead of conversational prose.
- For
- Developers building routing and triage systems
- Worth noticing
- It documents three typed primitives: noul, choice, and score, with batch-question cost and latency examples.
Field notes
Jev Notes frames Jev AI as a first-hop decision layer: classify, route, score, then hand off to code, a person, or a conversational model. Its examples use a support email as state and return separate decisions for human support, department, and urgency. The site also records implementation details such as named question keys, server-side API-key handling, batching guidance, and a 32,000-token context window.
