Overview

Jev Agent (jev-agent.com): the independent guide to Jev. It answers typed questions about a state and returns decisions with probabilities, not text. Measured cost and latency, API access, and where it fails.

AI summary

Jagent serves as an independent guide to Jev, a decision model by TypeSafe AI that processes typed questions and returns structured decisions with associated probabilities, rather than generating text. It is designed for applications requiring quick and reliable decision-making without the overhead of traditional language models.

Sources behind this listingSee source links, recorded dates and owner corrections.

Observed facts come from public pages. Founder-edited facts are supplied by the verified owner. AI-inferred facts are model interpretations; derived facts are calculated from other data. A source link lets you check the current page. It does not guarantee the fact is still current.

Dates show when a record was saved. Some older records use the listing’s update date; they are not proof of a fresh check. Missing source records are shown explicitly.
