Jev, a probabilistic decision model from TypeSafe AI, became the fastest-adopted model in AI Gateway history, reaching 13% of paid teams within 24 hours—twice the adoption of GPT-5.6 and six times that of Fable 5.1. Launched September 15, Jev is designed for structured decision-making in software, returning typed choices and probabilities rather than text, and reportedly performs up to 194 times faster and 445 times cheaper than general-purpose language models.
