Paperback. Condizione: new. Paperback. If your AI application is calling a large language model for every routing decision, tool choice, safety check, evaluation step, and automation trigger, you may be paying for far more reasoning than the system actually needs.Jev AI Decision Models in Practice shows you how to redesign that architecture around fast, bounded System One decision models-using heavyweight LLMs only when the task genuinely requires deeper reasoning or generation.This is a practical engineering book for developers who already know how to work with LLM APIs and now need to make their systems faster, cheaper, safer, easier to evaluate, and more predictable in production.You will learn how to identify decisions that do not require a full generative model and move them into a dedicated decision layer. Using Jev's Choice, Score, and Noul primitives, you will build systems that classify requests, estimate difficulty and risk, select tools, evaluate outputs, enforce guardrails, and decide when a task should continue automatically or escalate.The book develops one production-oriented architecture from beginning to end. You will learn how to: design bounded decisions instead of oversized prompts;route requests between deterministic code, tools, smaller models, reasoning models, and human review;build fast AI model routers based on intent, difficulty, and risk;select tools without giving the model uncontrolled execution authority;separate tool selection from argument generation and authorization;place decision-based guardrails before consequential actions;evaluate relevance, completeness, groundedness, and policy compliance;use confidence without confusing it with correctness;choose automation thresholds from measured behavior rather than arbitrary numbers;compare Jev against rules, classifiers, embeddings, and LLM-based alternatives;measure latency, escalation, review workload, and cost per successful task;regression-test model and decision changes before they reach production;design timeouts, bounded retries, circuit breakers, LLM fallbacks, and human escalation paths;observe exactly what the model saw, what it decided, which policy fired, and what happened afterward;secure the decision boundary around sensitive context and irreversible actions;keep the architecture model-agnostic so individual decision models can evolve without rewriting the entire agent.The examples are built around the problems that appear after an AI prototype starts becoming a real system: excessive model calls, unpredictable tool use, weak failure handling, arbitrary confidence thresholds, expensive evaluation pipelines, and too much authority concentrated inside one generative model.By the final chapter, you will have assembled a reusable production System One decision layer that can sit in front of agents, tools, workflows, and larger models-making routine decisions quickly, escalating uncertain cases deliberately, and keeping application code in control of what actually happens.This is not a book about replacing LLMs.It is about knowing which decisions deserve an LLM, which do not, and how to build the architecture that makes that distinction reliably.
