Jev versus text-generating models
Jev does not generate free-form text. A side-by-side video compares parallel decision-making with token-by-token text generation.

The author shares a decision hierarchy: deterministic problems get code, small bounded classification, routing, scoring, or fuzzy decisions use Jev, and generation, task completion, or moderate reasoning use a cheap API model.
My current hierarchy is becoming: Deterministic problem? -> Write code. Small, bounded classification, routing, scoring, or fuzzy decision? -> Use something like Jev. Generation, task completion, or moderate reasoning? -> Use a cheap API model like Luna or DeepSeek Flash.
