Jev
Explain how Jev, a decision model rather than a chat model, takes application state and a structured question, then returns typed probabilistic judgments for routing, scoring and classification.
Jev comes from TypeSafe AI and is the first public model on its System One path. The difference from GPT or Claude shows up in the output: instead of writing a paragraph, it maps application state and a structured question onto typed decisions with probabilities attached. OpenRouter lists Jev Latest and Jev 1.13 with a 32K context window, aimed at the routing and classification nodes inside ordinary software.
