Jev AI

About Jev AI

Jev AI is an independently operated platform providing access to Jev, TypeSafe's flagship System One model. Rather than generating text, Jev evaluates typed questions about any text and returns yes/no probabilities, choice selections with confidence scores, and numerical ratings—all processed in parallel and answered in about half a second.

The platform includes a browser-based playground for trying Jev interactively, batch processing tools for large datasets, and an API for integration. Users submit text (plain text or JSON) along with typed questions, and receive calibrated probabilities and confidence values suitable for routing decisions, evaluation tasks, and structured workflows.

Jev AI is independently operated by its own team, separate from TypeSafe which develops the model itself. The platform manages its own subscriptions, token balances, billing, and customer support.

FAQ

What is Jev AI?

Jev AI is an independent playground and API for Jev, the System One model from TypeSafe. You provide text and typed questions, and it returns yes/no probabilities, choices and scores with calibrated confidence.

What is the Jev model?

Jev is TypeSafe's flagship and the first System One model. It is trained for fast structured decisions instead of text generation: it evaluates many narrow questions about one state in parallel and reports how sure it is.

Can Jev read images or PDFs?

Native Jev accepts text only: a string, a JSON object or an array. For images, audio and short videos, select Jev-Omni in the Playground. PDF upload is not supported; convert PDF content to text first.

Which languages does Jev support?

English is Jev's primary language and where it is most accurate. Other languages work but less reliably, so you should test on your own data and watch the confidence value.

How does the Jev API work?

Create an API key and send the same JSON you would send to TypeSafe (state, model, questions) to https://jev-ai.pro/api/v1/systemone. API calls use the Token account first; model multipliers apply, and insufficient tokens switch the request to model-priced credits.
