Vercel reports that Jev, a specialized probabilistic decision model from TypeSafe AI, became the fastest-adopted model ever on AI Gateway: within 24 hours it reached 13% of paid teams — 2x the GPT-5.6 family and 6x Fable 5.1, with 10% penetration in just 18 hours. Jev takes context plus questions and returns typed choices, scores, or booleans with probabilities that code can consume directly, useful for agent decision points. Rauch Guajardo notes its adoption is amplified by the "AI is too expensive/slow" zeitgeist driving demand for optimization.
