CJ explains TypeSafe AI's Jev model as a fast System 1 classifier rather than a generative LLM. He demonstrates its API schema, reviews community implementations in routing and moderation, and builds an LLM-free chatbot executing deterministic tool calls.

Model intent and tool selection as bounded questions rather than requesting a free-form agent response.
The walkthrough replaces a long routing prompt with explicit categories that application code can branch on.
CJ’s chatbot demonstration selects tools and parameters for Home Assistant and Wikipedia; those applications still execute the selected operation.
Worth knowing
Tool-call classification still relies on clear parameter options and matching logic; deterministic branching does not guarantee correct real-world decisions if inputs are ambiguous.
