Jev AI: Frequently Asked Questions

Jev is TypeSafe AI's System One model. It returns typed decisions (Choice, Score, Noul) instead of generating prose. Unlike LLMs that produce text requiring parsing, Jev outputs structured, type-safe results perfect for classification tasks. Learn more at console.typesafe.ai.

Jev charges $0.042 per million input tokens. Output tokens are free. For context: a typical customer message (50-200 tokens) costs less than $0.001. New users get $5 in free credits (≈120 million input tokens). JevKit adds no markup — you pay Jev's rates directly.
