Jev Fundamentals: Decision AI for Beginners

Udemy Instructor

This course contains the use of artificial intelligence.What if your AI application could do more than generate answers? What if it could decide which model should handle a task, whether a tool call is safe, and when a human needs to step in?Welcome to Jev Fundamentals: Decision AI for Beginners, a hands-on introduction to Decision AI, AI agents, and intelligent automation. You'll explore how Jev by TypeSafe supports structured decisions inside real-world software, and learn to combine those decisions with clear business rules, confidence thresholds, and human oversight.Rather than watching disconnected demos, you'll build an evolving case study called BrightDesk DecisionOps. Starting with a simple customer-support classifier, you'll progress toward an AI decision engine that can route requests, evaluate risk, check evidence, and support safer agent workflows.What You'll Build and LearnYou'll begin with Python, the Jev API, and core decision concepts such as classification, scoring, and probability-based decisions. Then you'll learn how to design useful decision questions, interpret model outputs, set confidence thresholds, and handle uncertain results without treating every prediction as fact.Next, you'll explore LLM routing and AI model selection. Build workflows that choose between smaller and larger large language models (LLMs) based on task type, cost, and complexity. Integrate decision logic into LangChain and LangGraph, using structured application state, conditional branches, and human-in-the-loop approvals.You'll also tackle a critical challenge in agentic AI: deciding when an agent should be allowed to act. Build tool-call gating and AI guardrails that flag risky actions while enforcing permissions through deterministic code. Investigate prompt injection detection, AI safety, hallucination detection, citation verification, and retrieval-augmented generation (RAG) evidence checks.How do you know whether a decision model is actually improving your system? You'll create an AI benchmarking workflow that compares Jev with LLM classifiers and rule-based baselines, measuring accuracy, precision, recall, F1 score, latency, and inference cost. You'll learn why evaluation datasets, false positives, and confidence calibration matter more than flashy performance claims.Finally, we'll cover production AI engineering: model version pinning, API integration, fallback strategies, observability, audit logging, enterprise data security, privacy, and AI governance. Your capstone brings these skills together in a practical, reviewable Decision AI application.Who Should Take This Course?This course is designed for beginners, Python developers, AI engineers, software architects, automation builders, and professionals exploring generative AI or enterprise agent systems. Basic Python familiarity helps; prior Jev experience isn't required.Most examples use approachable code and synthetic business data. Optional local models can support comparisons, while live Jev exercises require access to TypeSafe's service. Because frameworks evolve, you'll also learn patterns that remain useful when SDKs and APIs change.You will leave with reusable project ideas for customer support automation, enterprise copilots, document review, and intelligent workflow orchestration. Whether you want to improve existing AI agents or prototype new applications, this course gives you a foundation.By the end, you won't just know the terminology. You'll have hands-on experience building AI systems that can route intelligently, verify evidence, measure performance, and escalate uncertainty—instead of blindly trusting every model response.

AI Security Fundamentals: Secure LLMs and AI Applications

Udemy Instructor

This course contains the use of artificial intelligence.AI is transforming software development, but every intelligent application introduces new security challenges. From chatbots and large language models to autonomous AI agents, organizations need professionals who understand how AI systems can be attacked—and how to defend them.Welcome to AI Security Fundamentals: Secure LLMs and AI Applications, a practical course covering AI cybersecurity, Generative AI security, LLM security, and the controls used to protect real-world AI applications. You'll move beyond theory to explore common vulnerabilities, implement defenses, and test your work through guided, hands-on labs.What You'll LearnYou'll start with AI security fundamentals, AI threat modeling, attack surfaces, and trust boundaries. Then you'll investigate the risks highlighted by the OWASP Top 10 for LLM Applications, including prompt injection, indirect prompt injection, sensitive data disclosure, data leakage, model supply chain attacks, and data poisoning.You'll also explore Retrieval-Augmented Generation (RAG) security, vector database security, access control, insecure output handling, and system prompt leakage. As AI applications become more autonomous, you'll learn to reduce AI agent security risks, excessive agency, tool-calling vulnerabilities, and unauthorized actions through least-privilege access, authorization checks, and human approval workflows.Security isn't only about finding vulnerabilities. You'll build defenses using input validation, output validation, PII redaction, authentication, API security, rate limiting, model integrity verification, and defense-in-depth architecture. You'll practice secure AI development, DevSecOps for AI, security testing, AI security monitoring, and incident response.Learn by BuildingThroughout the course, you'll work with BrightDesk, a fictional enterprise AI customer-support assistant. Step by step, you'll assess its architecture, identify threats, protect sensitive data, secure retrieval workflows, validate model artifacts, and control AI agent permissions.Hands-on exercises use accessible tools such as Python, FastAPI, Ollama, FAISS, and pytest. You'll learn how to perform controlled tests in a local environment, evaluate defenses, and document residual risks. No paid AI API subscription is required, and starter examples make the practical work approachable.You'll also become familiar with widely used guidance including NIST AI Risk Management Framework (AI RMF), MITRE ATLAS, and OWASP LLM security resources.The final capstone connects everything: you will create a security checklist, map AI application vulnerabilities, add practical safeguards, run security regression tests, and present findings to stakeholders. This mirrors how real teams collaborate across engineering, architecture, privacy, and security—not by promising perfect protection, but by continually improving measurable controls over time.Who Should Enroll?This course is designed for software developers, AI engineers, solution architects, cybersecurity analysts, security engineers, DevSecOps professionals, and technical leaders responsible for deploying AI safely. Beginners are welcome; basic Python familiarity is helpful for coding exercises but not mandatory.By the end, you'll have more than a vocabulary of AI threats. You'll have practiced applying security controls, producing an AI security risk assessment, and building a portfolio-ready secure AI application prototype. Whether you're securing your first LLM-powered chatbot or reviewing an enterprise AI architecture, you'll leave with a practical foundation for making AI applications more resilient.Enroll and start building AI systems with security in mind from day one.
