System One Decision Models with Jev
System One Decision Models with Jev is a practical guide to using structured decision models alongside generative LLMs in AI agents. It covers Jev and open-weight alternatives, LangChain integration, local use with Ollama, classification, scoring, routing, and confidence-based controls for agent actions.
At a glance
- Explains how structured decision models can return probabilities, scores, and classifications instead of free-form text.
- Describes combining Jev and open-weight alternatives with generative LLMs in agent workflows.
- Covers LangChain integration and running models through hosted APIs or locally with Ollama.
- Includes examples involving classification, scoring, triage, routing, and confidence-threshold gating.
