Official path: TypeSafe console
The source of truth is typesafe.ai and console.typesafe.ai. Create a key, store it as TYPESAFE_API_KEY, and call POST https://api.typesafe.ai/v1/systemone. Do not paste keys into frontend bundles.
Early access opened with the 15 September 2026 launch. Checked 21 September: typesafe.ai/join-the-waitlist is a 404, the homepage CTA is Sign up, and the Console has Playground plus Create key. Recap: /jev-api-open.
Gateway path: Vercel AI Gateway
If you already ship on Vercel, the Gateway model ID is typesafe-ai/jev. Published input pricing matches TypeSafe’s $0.042 per million tokens. This is useful when you already have Vercel billing and do not want another vendor account yet.
What “access” does not include
A key does not make Jev open source, on-prem, or multimodal. Current docs describe text state. Image, audio, and video are out of scope. You still need a generative model for anything a person will read.
- Official: console.typesafe.ai
- HTTP: POST https://api.typesafe.ai/v1/systemone
- Gateway: typesafe-ai/jev
- Pin jev-1.13.0 once thresholds are tuned
FAQ
How do I get access to Jev?
Sign in at console.typesafe.ai, create an API key under API Keys, and set TYPESAFE_API_KEY. As of 21 September 2026 the waitlist URL 404s and the Console is a public login.
Is there a Jev playground with no signup?
TypeSafe’s official playground is in the console after you sign in. Independent playgrounds exist, with their own keys and limits. This site’s homepage demo is a local shape example, not a live Jev call.
Can I use Jev without a TypeSafe account?
Vercel AI Gateway lists the model as typesafe-ai/jev at the same published input price. OpenRouter and Cloudflare have also listed Jev. Those are gateway paths with their own billing.
