A typed decision layer for real workflows
Watch how the playground turns a plain text description into structured decisions your application can act on immediately — no prompt engineering needed.
Jev Model use cases
Use Jev AI where products need a decision, not a paragraph
Jev AI is strongest when a workflow needs a compact, auditable answer: route this ticket, moderate this post, classify this chatbot intent, score this lead, approve this agent action, or decide whether a request should continue. Each use case gets a typed JSON response — no free-text parsing, no prompt tuning, just decisions your code can act on.
Jev AI moderation gates
Return approve, block, escalate, or review decisions before content, transactions, or agent tool calls reach production systems.
Jev API agent workflows
Give agents a narrow typed decision contract before they change billing data, issue refunds, call tools, or contact customers.
Jev Model scoring
Turn free-form sales, support, risk, and onboarding text into labels, routes, confidence scores, and audit-friendly explanations.
Typed JSON decisions
Keep downstream code simple by asking Jev AI for stable JSON fields such as decision, confidence, reason, and answers.
API resale foundation
Sell Jev API credits, issue user API keys, meter calls with credits, and keep the public JevModel endpoint stable for customers.
Typed schemas
Define your own decision vocabulary
A Jev Model request describes the state, asks one narrow question, and defines the decision vocabulary your application can safely execute. The response echoes every question key with the label the model chose, so there is nothing to parse out of free text. That keeps Jev AI fast, predictable, and audit-friendly — a solid foundation for API resale or internal workflow automation.

Jev Model FAQ
Questions about Jev AI and Jev API access
Is Jev Model a chatbot?
No. Jev Model is better positioned as a fast typed decision layer for labels, routes, scores, and workflow gates.
How is Jev AI different from a normal LLM answer?
A normal answer explains. A Jev AI decision returns a compact decision object your product can route, meter, log, and execute.
What does a Jev API response look like?
Every response returns structured JSON with a decision label, a confidence score whenever the model provides one, a reason, and an answers map keyed by your question keys — ready for your application logic without any text parsing.
Can I use Jev API without signing in?
The homepage Jev Model playground gives 10 free decisions a day, signed in or not. A Google account adds an API key, 100 decisions a day on the public API, and 1,000 gift credits.
How do I get a Jev API key?
Sign in with Google, open Settings, create an API key, buy Jev API credits, and call the /api/v1/decisions endpoint.
How are Jev API credits measured?
Each decision call consumes 1 credit, regardless of the number of questions. Responses include remaining credit balance for easy monitoring.
Does the Jev API expose your supplier?
Yes, for traceability. Every response includes the upstream provider, the exact model build, and the upstream request id, so you can verify which model answered. Routing itself stays behind the JevModel endpoint and response contract.
Can Jev Model power API resale?
Yes. JevModel includes Stripe credit packs, API key management, credit metering, and a stable Jev API endpoint.
