Jev for startups
Startups should treat Jev as a narrow production habit: pin a model, freeze five questions, log traces, abstain. Not as a branding layer called “our AI brain.”
Unofficial startup notes — not fundraising advice, not a key desk. Access is waitlist/console; we do not issue keys. docs.typesafe.ai. Replicas are not Jev and not endorsed.
First 30 days
- One door (channels).
- One questions module in git.
- Dual-stack smoke if you ship Py and TS.
- Gold JSONL with 50 ugly real tickets.
- Fail closed on 401/422/timeout.
What to skip
Multi-door abstractions, custom fine-tunes (not offered), and generating user-visible copy with Jev.
Risks if you skip the boring parts
A startup that pastes Playground output into production without a pin will retune floors after every alias move. A startup that asks Jev to write onboarding email will hit jaggedness (generation) and still need an ESP. Keep the first production loop boring: one door, one questions file, one gold set, one fail-closed default.
Vendor list price is cheap per call at $0.042 / M input — until you send the whole CRM row. Filter. Official: unused state still bills and hurts jev-1.13 accuracy.
If you only have OpenRouter or Vercel credentials this week, use that door’s model id. Do not copy first-party noul examples into a boolean schema.
Two pins the 30-day list forgets
Add these to the first-month loop, not instead of it:
- Put instructions, criteria, and floors in one questions file.
- Filter
stateto the fields you judge. Official: unused state still bills and hurtsjev-1.13accuracy. - Pin
jev-1.13.0the moment a floor exists.jev-latestcan move. - Official SDKs retry 429/529 only — fail-closed is still your default when retries end.
Confirm list price on the models page (they have described output as free). Treating SemIf as “Jev we can run on a laptop” is out of scope — not Jev and not endorsed.
Then graduate with implementation checklist. Enterprises later: for enterprises. Hello-world access: getting started.
When not to use this page’s advice
Do not build an “AI platform” narrative for a seed deck on the back of one Noul. Do not skip gold because you are three people. Do not buy keys from a guide site. Schema-safe ≠ your first customer’s ticket is correct. Do not use Jev as persistence, math, or the ESP.
What this page does not claim
- Not fundraising advice.
FAQ
Is Jev cheaper than GPT for everything? Only if you stop generating on decide-only traffic. Measure. Vendor list price is $0.042/M input.
OpenRouter for speed to hello-world? A documented door — different model id and errors (402). Don’t mix schemas.
Can we fine-tune Jev on our tickets? Public docs we used say no customer LoRA. Do not plan a seed milestone on it.
Is OpenJev fine for the MVP? It is not Jev. If you use it, label it. Floors will not transfer.
