Jev from Typesafe generates structured output instead of text for fast, cheap classification tasks
LangChain · x · 2026-09-19
LangChain is amplifying a 20-second explainer from @sydneyrunkle on Jev, a tool from @typesafeai. Unlike LLMs that generate text, Jev emits structured output directly, making it a strong fit for classification-style workloads: model routing, tool selection/search, and many kinds of guardrails. The pitch is that it's dramatically faster and cheaper than using an LLM for these same tasks.
