What does Clef Omni do?

It turns a state and typed questions into decisions, returning a probability for every allowed option. It is a decision model, not an open-ended chat LLM.

What inputs can Clef Omni process?

It accepts plain text or structured JSON state, with optional embedded PNG, JPEG, or WebP images, audio, and video.

What question types are supported?

The API supports noul, choice, and score questions. Answers are returned under the same question IDs.

Is Clef compatible with Jev and System One?

Yes. Clef uses the same state and noul, choice, and score question shape, so an existing integration can switch endpoint and model.

How much does the API cost?

Prepaid packs are $5 Developer, $20 Production, and $100 Scale. One credit is approximately one input token; output probabilities are not billed.

Can it process images, audio, and video?

Yes. Clef Omni supports embedded media. The API allows up to four images, four audio files, and two videos per request, subject to the documented size and duration limits.

Is there a free way to try Clef?

Guests receive three free playground runs, and registered users receive 10,000 one-time welcome credits. Identical cached playground and API hits are free.

A demo playground and hosted API for Clef Omni, a multimodal decision model that reads text, images, audio or video and returns probabilities for each allowed option. Free anonymous runs; prepaid packs from $5.

What Clef Omni Demo does

Typed decision questions: Use noul, choice, or score questions and receive probabilities for the defined options.
Multimodal inputs: Evaluate plain text or JSON state with optional embedded images, audio, and video.
Agent routing: Score a closed list of tools or branches and apply confidence thresholds before routing.
System One compatibility: Use the same state and noul, choice, and score question shape as System One and Jev.
Hosted REST API: Send authenticated requests to the hosted decide endpoint with TypeScript, Python, or curl.
Online playground: Prototype support triage, incident response, content gates, and other decisions in the browser.

Who it's for

Developers and teams building agent workflows that need classification, routing, scoring, moderation, or other structured decisions.

Why people use Clef Omni Demo

Generic chat models can be costly or unsuitable for simple, closed-list routing and classification decisions.

Clef accepts context and typed questions, then returns structured probabilities for the available answers so workflows can route or score based on thresholds.

It combines multimodal inputs with typed decision questions and a System One / Jev-compatible schema.
