Jev: a model that decides, with the output side priced at zero
The first of TypeSafe's System One models. It does not write prose — given a decision to make, it returns a typed result your code can consume directly, with no parsing or fallback layer around it. Because the output is not long-form text, the output side is priced at zero: you pay only for what goes in ($0.042 / 1M), with a 32K context. It fits wherever your system has to judge something and then branch — intent detection, content triage, ticket routing, tool selection.
