Jev in production › SDKs and workflow integrations
n8n node calls Jev System One models to evaluate or route workflow items with typed yes/no, pick-one or scale questions.

This n8n community node lets your workflows call TypeSafe AI's System One models. You give a System One model a state, which is the content you want judged, plus typed questions about it. The model returns a structured answer to each question, with probabilities. Jev is TypeSafe's flagship model and the first System One model.
The node has two operations. Evaluate adds the answers to each item. Route picks an output for each item based on the answer to one question.
