Jev and LangGraph for AI workflows that keep control in code
LangChain says Jev was 5–6x faster than Sonnet at classifying pages in its document-review demo, with LangGraph routing pages to an LLM or an attorney when needed.
TLDR
LangChain describes pairing TypeSafe AI’s Jev decision model with LangGraph: Jev returns structured answers with probabilities instead of generating text, while LangGraph manages which step runs next. In its litigation document-review demo, Jev classifies pages, an LLM redacts personal information, and potentially privileged pages trigger a pause for attorney review. LangChain reports Jev was 5–6x faster than Sonnet on the classification step across trials. The article emphasizes that Jev does not fully replace an LLM for most use cases, describing an approach that reserves LLMs for open-ended reasoning and decisions Jev is unsure about.
