He Helped Build ChatGPT. Now He Says It Was a Detour — Jev
This video breaks down TypeSafe AI's Jev decision model, contrasting its single-pass probabilistic architecture against autoregressive text models. It critically evaluates TypeSafe's RLCD claims, pricing assertions, and vendor caveats.

Jev replaces autoregressive text generation with a single-pass parallel sampler that outputs typed choices, probabilities, and scores.
TypeSafe's 0% hallucination claim is an enforced structural guarantee of schema matching, not verified factual correctness.
RLCD aims to produce confidence scores for automated routing, though external technical papers and independent benchmarks remain unreleased.
Worth knowing
TypeSafe's advertised speed evaluations were run internally near their servers, pricing may be subsidized, and no independent calibration benchmark or technical architecture paper has been published.
