Jev Decision Engine

Jev acts as a decision engine, determining when to use an LLM for writing tasks, with user code controlling the execution gate.

TakeReplace the LLM call only where it was picking, rating or judging.

Jev cannot write a sentence. That part is true. Four things the tutorials still get wrong: → Not multimodal. Text only — no image, audio, video. → Noul has no confidence field. One bare probability. Wire a boolean into a confidence gate and that gate does not exist. → Two context ceilings, not one. 64k per request, 32k for state + your single longest question. Nothing is reserved — but a big state plus one long question hits 32k while you're nowhere near 64k. → 193.6x / 444.6x are TypeSafe's own workflow evals. A vendor ceiling, not your workload. Replace the LLM call only where it was picking, rating or judging. Never where something has to be written. Jev decides. The LLM writes. Your code holds the gate.
