## What Jev is

Jev is TypeSafe AI's first System One model. It takes a state plus typed

questions whose answer space is fixed in advance and returns constrained

answers with probability distributions, rather than generating text. The

primitives are Choice, Score and Noul. Endpoint: POST

https://api.typesafe.ai/v1/systemone, model jev-latest.

## Evidence grades

- official: published by TypeSafe AI itself

- observed: found used in real code, or its own text cites the API

- inferred: declared in a repository name or an explicit topic tag

- unverified: matched on vocabulary alone

The grade describes how much was verified, not how good a project is.
