LangGraph maps well onto Jev, TypeSafe's new decision-making AI model

TypeSafe AI last week released Jev, a new kind of model that doesn't generate text — it outputs decisions your code can act on directly. A new article shows how to build production apps with Jev and LangGraph.
Josh Rosen argues LangGraph's core abstraction — putting decisions into state, then routing based on them — maps naturally onto Jev. He speculates LangGraph may come to be seen less as agent orchestration and more as simply how you build software with composable models. LangChain founder Harrison Chase amplified the thread.
