New notebook example shows how to use decision model Jev as an agent's next-step judge
_nerdai_ · x · 2026-10-01
Author nerdai added a bonus example to Chapter 4 of his Manning early-access book Build a Multi-Agent System (From Scratch), answering how to actually use a decision model like Jev inside an agent: in the book's processing loop, the backbone LLM decides after every step whether to continue or return the result, with Jev serving as that next-step judge. The accompanying Jupyter notebook is open-sourced in the llm-agents-from-scratch GitHub repo.
