Alessio Garau examines TypeSafe AI's Jev, explaining how System One models replace autoregressive text generation with decision primitives. He critically reviews reported latency and hallucination claims.

Jev replaces token-by-token text generation with predetermined decision primitives that return probability distributions and confidence scores.
Vendor claims of low hallucination rates stem from constrained output spaces rather than infallible reasoning, meaning miscalibration remains possible.
A practical architecture delegates routing, tool selection, or game actions to fast System One models while reserving full LLMs for text generation.
Worth knowing
All benchmark latency, cost, and accuracy numbers originate from TypeSafe's proprietary announcements rather than independent evaluations. Italian-language video.
