TypeSafe launched Jev on 2026-09-15, though direct access still appears uneven rather than broadly open to every account. The Ofox.ai Jev guide documents a hosted endpoint and API-key flow, while the access walkthrough says signing in alone may not be enough to actually send requests through TypeSafe.
Jev is positioned as a low-cost decision layer for narrow tasks such as routing, scoring, classification, workflow continuation, and guardrail checks. Instead of a chat-style prompt that returns prose, it uses a typed request format built around state and explicit questions, then returns structured outputs. The reported direct price is $0.042 per million input tokens, with no output-token charge.
For builders, that makes Jev more useful ahead of expensive generation than as a replacement for it. Teams can use it in shadow mode for triage or policy gating, but should still calibrate thresholds on their own labeled data and keep a fallback for risky decisions.
