Why do I need a bridge instead of calling Jev directly?

Routers and IDE agents only speak OpenAI-style APIs while TypeSafe serves its own decision endpoint without streaming. The bridge translates requests locally so existing tools can call Jev unchanged.

Should my agent use Jev for writing code too?

Keep them separate: the chat model writes code and prose while Jev answers what-is-true decisions like verify, triage, rank, and route. Never route coding tasks to Jev.

Does my TypeSafe key leak to every connected client?

Your TypeSafe key stays in the bridge environment file and clients use a placeholder or shared bridge token. The bridge binds loopback only, guards Host headers, and allow-lists browser origins.

What happens when Jev is unsure about a routing call?

Below the confidence threshold the CLI flags low confidence and exits nonzero so scripts can react. Yes-or-no answers in the middle band mean uncertain, so gather more evidence.

How do I start the bridge?

Node 18+ and a TypeSafe API key; npm run setup asks for the key, starts the bridge on http://127.0.0.1:8399/v1 and smoke-tests it. Then point any OpenAI-compatible tool at that base URL with the placeholder key sk-typesafe-bridge.

Which endpoints does it expose?

POST /v1/chat/completions and POST /v1/responses, including SSE streaming, both translated into TypeSafe /v1/systemone calls, under the model ids typesafe/jev-latest and typesafe/jev-preview.

What protects the bridge?

It binds loopback only and rejects non-loopback Host headers, origin-checked browser requests are rejected unless allow-listed in BRIDGE_ALLOWED_ORIGINS, and BRIDGE_TOKEN can require a shared secret; the CLI redacts secret-like values before sending.

About this project

Most AI models generate text. Jev doesn't — it answers typed questions with calibrated probabilities: a yes/no likelihood (noul), a choice among options, or a score on a rubric you define. You give it state (any text or file) plus questions; it gives your code answers it can act on. It's fast and cheap, and it says "I'm not sure" when it genuinely is — instead of making something up.

Highlights

Translates chat completions and responses requests, including streaming, into decision calls.
CLI asks choice, score, and yes-or-no questions with confidence and distributions shown.
Loopback-only service with origin allow-list, optional shared token, and secret redaction.
Works with routers, IDE agents, or any OpenAI SDK without global installs.

C# client for Jev, TypeSafe AI's System One model. Typed Noul, Choice and Score questions go out with one state in a single round trip and come back with a value, a probability distribution and a confidence number. Choice questions can be built from an enum, so the compiler finds the switch branch you forgot.
