Key Info

Jev, a System One model by typesafeai, is now in beta on OpenRouter. Instead of generating plain text, it returns typed decisions with confidence probabilities for each option.

Highlights

  • Ask a question and get a clear probability breakdown, e.g. “billing 84%, technical 16%”.
  • You can ask several questions about the same input in a single call.
  • Jev uses your app's state plus a typed question to produce a typed decision.
