Vercel reports that Jev, a probabilistic decision model from TypeSafe AI, became the fastest-adopted model on AI Gateway within 24 hours of launch, reaching more than twice as many paid teams as any previous model. By hour 24, nearly 13% of paid teams were using it, outpacing GPT-5.6 and Fable 5.1. TypeSafe AI states Jev is up to 194 times faster and 445 times cheaper than language models in its own evaluations.
