JevStation

JevStation is a development workspace where users run Jev to evaluate text states and receive typed answers with confidence scores.

JevStation is a workspace for running Jev, TypeSafe's System One model, along with Cloudflare Clef, Perplexity Decider, and OpenAI Luna Decisions. Users paste text states such as support tickets or reviews, add up to twelve Choice, Score, or Noul questions, and receive structured answers complete with probability distributions and confidence scores. The platform stores evaluation threads with auto-derived titles, supports reusable question sets and playbooks, and provides credit metering where standard runs cost one credit and larger runs cost three. It is built for developers and teams who need direct judgments for code branches rather than generated text. JevStation offers 50 free credits upon sign-up and one-time credit packs starting at $9.90.
