Features

JevStation is a hosted workspace for typed decisions. You paste a state, such as a ticket, a review, a spec or a JSON record, ask up to 12 questions of the kinds Choice, Score or Noul, and get a typed value, its probability distribution and, for Choice and Score, a confidence value. Noul is a probability from 0 to 1. The workspace runs TypeSafe's System One model Jev together with Cloudflare Clef, Clef-flash, Perplexity Decider and OpenAI Luna Decisions on the same API key. Saved threads, the batch page at https://jevstation.com/batch, the docs at https://jevstation.com/docs and MCP at https://jevstation.com/api/mcp are part of the product. https://jevstation.com/about says JevStation is not TypeSafe and uses the TypeSafe API as a customer, so it cannot change the model, its price or its availability. The same page says the app runs as Next.js on Cloudflare Workers, and that evaluation content is not used to train models.

The pricing page, updated 2026-10-04, lists 50 credits on sign-up, valid for 30 days, and 3 playground runs each day without an account. Packs cost 9.90 USD for 5,000 credits and 15.90 USD for 12,000 credits, valid for 24 months, with no subscription. A standard run costs 1 credit when the state stays within 8,000 characters and the set stays within 5 questions; a larger run costs 3 credits. Clef costs 2 credits or 6 credits. Failed runs are refunded. The same page cites TypeSafe's list price as 0.042 USD per 1,000,000 input tokens, with output not billed, and says TypeSafe access is a waitlist without self-serve checkout. It also says the largest request the site accepts is 12 questions and 24,000 characters of state. Terms and privacy dated 2026-09-19 name the operator only as JevStation, with contact support@jevstation.com, and they publish no legal form and no address. The privacy policy describes stored state as up to 8,000 characters and attached context as up to 2,000 characters. The terms require the account holder to be at least 16. The playground is at https://jevstation.com/playground and sign-up is at https://jevstation.com/sign-up.
