Jev Model

What It Does

Jev Model is a specialized AI decision engine designed to turn unstructured context into fast, typed, structured decisions with probabilities. Unlike generative LLMs that produce open-ended text, Jev Model answers bounded questions with defined answer spaces — returning classifications, scores, and yes/no judgments that integrate directly into application logic, routing systems, guardrails, and automated workflows.

Who It's For & The Problem It Solves

Jev Model is built for developers, product teams, and AI engineers who need to make small, high-frequency decisions inside production systems without losing control. The hardest product work is often not generating a paragraph — it's making the right call on intent classification, urgency scoring, safety checks, or model routing thousands of times per second. Jev Model handles these "System One" decisions reliably and returns results in a format your code can act on immediately.

Key Features & Capabilities

• Three Question Types: Use Choice for classification (e.g., intent detection), Score for continuous assessment (e.g., urgency levels), and Noul for yes-or-no questions (e.g., "needs human review?").
• Multi-Question Requests: Ask up to eight typed questions against the same context in a single API call — get independent answers for intent, sentiment, urgency, and escalation at once.
• Probability & Confidence: Every answer includes a probability score (0–1), enabling threshold-based routing, quality gates, and human-in-the-loop fallbacks.
• Fast Latency: Typical decision latency around 120ms makes it viable for real-time classification, routing, and guardrails.
• Developer-First Integration: REST API, typed SDKs (Python, Node.js, Go, Java), clear JSON schemas, and manageable API keys take you from playground test to production integration quickly.
• Agent Skill Support: Install the Jev Model Agent Skill for Codex, Claude Code, Cursor, and compatible coding agents to use typed decisions for routing, verification, and completion checks.

Typical Workflows & Use Cases

Jev Model fits into several critical decision points:

• Model Routing: Assess task difficulty first, route simple requests to fast models, and escalate complex ones to larger LLMs.
• Tool-Call Safety Gates: Check intent and risk before a tool executes — ask for confirmation on destructive actions like deletion or payment.
• Support & Lead Triage: Classify intent, urgency, sentiment, and human-review needs together to route tickets into the right queue.
• Content Moderation & Guardrails: Use typed decisions to block spam, flag harmful content, or enforce policy before output reaches users.
• Context Compression: Decide which tool results or session facts still matter when condensing long conversation histories.

Integrations

Jev Model integrates via REST API, SDKs (Python, JavaScript/Node.js, Go, Java), and an Agent Skill for AI coding assistants. It accepts text, JSON objects, and arrays as state input. The playground is free with unlimited runs, and API plans include unlimited usage during their access period.

What Differentiates It

Jev Model is purpose-built for structured decision-making, not generative output. It separates state, questions, and actions — the model only handles the decision in the middle, leaving your business logic, permissions, and approval workflows intact. This makes it a complement to LLMs, not a replacement: use Jev for routing, guardrails, and classification; use LLMs for generation.
