Automated README summary
Automatically summarized from the README on 3 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
ComfyUI nodes that let a workflow branch on natural-language judgments from System One decision models (Laya, Jev, Clef). Useful for ComfyUI users who want to route or gate generation based on prompt or image content.
How it uses Jev
Jev is one of three interchangeable backends. Nodes send a state (usually the prompt) and typed questions (Choice, Yes/No, Score) to Jev via its hosted API. The returned label, probability, or score, with confidence, is used to route branches, gate generation, or swap prompts.
Primitives:choicescorenoul
Technique worth stealing
Use a confidence threshold with fallback to avoid branching on uncertain model answers.
Try it
Install via ComfyUI Manager or `comfy node install comfyui-systemone`; set `TYPESAFE_API_KEY` for Jev.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
