About this site
Jev Developer Platform (jevtypesafe.org) is an independent community resource and hosted tool host for developers building with Jev — TypeSafe AI’s System One decision model. We are not affiliated with TypeSafe AI.
What we provide
A free playground and ready-made decision tools, a metered hosted decide API with customer jv_live_ keys, prepaid input-token packs, unofficial developer docs (SDK concepts, System One, use cases, FAQ), and practical guides that focus on implementation tradeoffs — not product marketing copy.
Who operates it
The site is operated by Anderson (GitHub: anderson188). Editorial and engineering work for this host is attributed to that maintainer. For trust and support contact details, see the Contact page.
Affiliation & compliance
This is an unofficial community resource. We are not affiliated with TypeSafe AI. Jev model inference on this host runs through Cloudflare Workers AI / gateway on our servers. Buying packs here purchases prepaid capacity on this platform — not raw upstream vendor keys.
Source material
Definitions and product facts are rewritten from public TypeSafe materials for developers. Source reference: TypeSafe AI official announcement blog post on System One models and Jev. We add implementation notes, pitfalls, and hosted-product specifics that the announcement does not cover.
