Vercel Developers announced that Jev from TypeSafe AI is now available on Vercel's AI Gateway. The post positions Jev for building agents that decide, route, score and stop in milliseconds, and shows it being called through an evaluate function with the model identifier typesafe-ai/jev plus state and questions arguments.
The call shape suggests Jev is meant for fast control decisions inside an agent loop, such as whether to continue or which path to take, rather than for generating long responses. The post gives no latency measurements, accuracy figures or pricing, so the millisecond claim is not substantiated in the source.
