How Jev is used
Cloudflare Workers AI exposes TypeSafe's Jev model under the id typesafe/jev. From a Worker you call env.AI.run with structured state and noul, choice, or score question shapes, same System One contract as the TypeSafe API.
Setup: Follow Cloudflare's Workers AI binding docs for model id typesafe/jev. Dollar pricing is managed in the Cloudflare dashboard rather than on the public model card.
When to use Workers AI vs TypeSafe direct
Pick this path when you already deploy on Cloudflare Workers and want Jev beside your other AI bindings without juggling a separate TypeSafe API key in every environment.
