Jev figures from its public documentation, September 2026.
When layahost is the better fit
- Longer texts. Jev charges per input token, layahost per decision. With one question per request, flat pricing is cheaper above about 119 tokens: support tickets, emails, reviews and documents.
- EU data residency. Requests are processed on servers in the EU and the text is not stored by default.
- An open model. Laya is Apache-2.0. If you outgrow a hosted API you can run the same model yourself, with no change in behaviour.
- Ready-made decisions. Moderation, spam, routing, intent, sentiment, priority and language as one-line calls to
/v1/decide.
When to stay with Jev
- Very short texts at high volume. Below about 119 tokens per request, Jev’s per-token price is lower.
- Accuracy is everything. Independent tests put Jev ahead of Laya on some tasks. Measure both on your own data first.
- You need higher default limits than 600 requests per minute and can’t wait for a raise.
Switch in three steps
- Create an account and verify your email ($1 of credit to test with), then create an API key.
- Set
TYPESAFE_BASE_URL=https://layahost.comandTYPESAFE_API_KEYto your layahost key. - Replay a sample of real traffic and re-check any probability thresholds before moving production.

Is layahost affiliated with TypeSafe AI?
No. layahost is an independent service. “Jev” is TypeSafe AI’s product name, used here only to describe API compatibility.
Will my probabilities be the same?
No. Answers have the same shape, but a different model produces them, so the numbers differ. Treat thresholds as something to re-tune.
Can I use layahost and Jev side by side?
Yes. Because the API is the same, you can route a share of traffic to each and compare answers before deciding.
