Is Jev Free? Free Tiers and Trials for the Jev API
Last checked · Independent guide, not affiliated with TypeSafe AI
Not really. TypeSafe charges $0.042 per million input tokens and nothing for output, and OpenRouter charges the same with no free tier. The closest thing to free is Vercel AI Gateway, which listed Jev as free under a promotion ending September 25, 2026 and gives every team $5 of monthly credit, but it requires a card on file and throttles free-tier requests hard.
Jev has one unusual pricing rule that makes it cheap even when it is not free: output tokens cost nothing. You pay only for the text you send in. Beyond that, whether you can use it for free depends on where you call it.
Free options by channel (as of September 19, 2026)
Section titled “Free options by channel (as of September 19, 2026)”| Channel | Free? | The catch |
|---|---|---|
| TypeSafe API | No published free tier or trial | Access is early access through a waitlist; pricing is $0.042 per million input tokens |
| Vercel AI Gateway | Listed as free for input and output; $5/month free credit per team | Promotion ends Sep 25, 2026; a card must be on file; free-tier requests are heavily throttled |
| OpenRouter | No | Needs prepaid credits; $0.042 per million input tokens, $0 output |
| Cloudflare Workers AI | Not stated | Price for Jev is only shown in the Cloudflare dashboard |
The Vercel route in practice
Section titled “The Vercel route in practice”Vercel’s free tier works for trying Jev, with two conditions. First, the Vercel team needs a payment card on file; without it, calls fail with customer_verification_required. You do not have to buy credits. Second, free-tier requests are rate-limited per model. In our testing, a batch of 131 questions took about an hour and a half because Vercel let a few through at a time.
Do not buy credits just to lift the limit unless you mean to: Vercel’s pricing docs say that purchasing credits moves the team to the paid tier and ends the monthly free credit. Step-by-step setup: Jev on Vercel AI Gateway.
How much does Jev cost if you pay?
Section titled “How much does Jev cost if you pay?”Very little per request. A short customer message with three questions used 451 input tokens in our test, which is about $0.000019. One dollar covers roughly 50,000 requests of that size. A 26,000-token document costs about a tenth of a cent per call. Details and more examples: Jev API pricing.
Is there a free trial on TypeSafe itself?
Section titled “Is there a free trial on TypeSafe itself?”TypeSafe’s website and documentation do not advertise a free trial or free credits as of September 19, 2026. Once your account is approved, the console includes a Playground for trying questions in the browser; TypeSafe does not say whether Playground calls are billed.
Free ways to experiment without Jev
Section titled “Free ways to experiment without Jev”- Open-source lookalikes. Several community projects imitate Jev’s interface with small open models you can run yourself. They are not Jev and their quality claims are their own. See Jev alternatives.
- TypeSafe’s own adapter. TypeSafe publishes an open-source Python package that answers the same Noul, Choice and Score questions using an LLM from OpenAI or Anthropic instead of Jev. It is meant for comparing the two, and you still pay the LLM provider.
Bottom line
Section titled “Bottom line”If you want zero cost, the Vercel promotion is the only no-charge route to the real model, and it has an end date. If you just want low cost, any channel works: at Jev’s prices, most prototypes spend less than a dollar.
