TypeSafe AI launches Jev, a transformer that outputs probabilities, not text

TypeSafe AI released Jev, a transformer-based model that is not a large language model. It does not output text but produces probabilities described as calibrated decisions. TypeSafe states users define Jev's outputs in advance, so it cannot hallucinate. The company classifies Jev as a System One model for programmatic decisions. Announced September 15, 2026, in San Francisco.
