🚀Function Overview

A text-only decision model for ranking, routing, filtering, scoring and other bounded choices where compact calibrated probabilities are more useful than generated prose.

Key Features

Current dated model ID jev-1.13.0
Moving alias jev-latest currently points to Jev 1.13
POST /v1/systemone request surface
Typed Choice, Score and Noul decision primitives
Text, strings, JSON-like state and arrays as input; no image, audio or video input
Probability and typed decision output; no prose, code or reasoning explanation generation
64,000-token overall request limit documented by TypeSafe
32,000-token state budget plus the longest question
$0.042 per million input tokens with no output-token charge
English is the primary language; CJK support is documented as uneven
Customer requests and responses are not used for training; zero-data-retention is an enterprise option
Group-level calibration requires task-specific thresholds and fallbacks

Use Cases

•Rank candidate actions, documents, code paths or search results
•Route a request to a model, tool, workflow or human reviewer
•Filter browser content and agent tool output
•Score policy, relevance, quality or safety criteria
•Choose navigation edges in browser, desktop and graph agents
•Triage cases before a slower reasoning or generative model

Input Parameters

{
  "model": "jev-1.13.0",
  "state": "The user asks the agent to summarize a public document and provides a valid URL.",
  "questions": [
    {
      "type": "choice",
      "prompt": "Which route should handle this request?",
      "options": [
        "read-only fetch",
        "write-enabled browser",
        "human review"
      ]
    }
  ]
}

Output Results

A typed probability distribution over the allowed routes. Application code must choose and validate the threshold; Jev does not execute the route or explain the decision.
