TypeSafe.Jev

How it uses Jev

Jev is TypeSafe AI's System One model. You hand it some state and a set of small typed questions, and it answers each one with a value, a probability distribution and a confidence score . No prompt engineering, no "please respond only with JSON", no stripping code fences off the reply.

Highlights

• Your enum is the question. Declare the options once, get that enum back, and let the compiler find the
• Confidence is a first-class number. Auto-approve above your threshold and route the rest to a human.
• One dependency. Microsoft.Extensions.Logging.Abstractions , and nothing else. CI reads the packed
• Trim- and Native AOT-safe. A native binary is published and run on every build to prove it.
• Retries that match the official SDKs. 408/429/5xx, backoff with jitter, Retry-After , per-attempt
• Logging and OpenTelemetry built in , through ILogger , ActivitySource and Meter — no extra packages.

Getting started

Questions are independent and answered in one round trip, so ask everything about a state together: the state is tokenized once, and you get one consistent read of the same text.
