Course Overview
Explore key concepts in applied AI engineering to build and operate reliable AI applications. Understand how to integrate models, tools, and data for performance, security, and scalability. Gain insights into managing multi-modal inputs, deployment practices, and safeguarding user data in real-world systems.
Welcome to Applied AI Engineering.
Applied AI engineering turns AI capabilities into applications that solve real problems reliably. It brings together models, software, data, tools, and infrastructure to build and operate complete applications.
When building an AI application, we need to decide how the model accesses information, uses tools, and communicates with other components. We also need to understand how data moves through the system, which types of input it handles, and how it performs as demand grows.
As applications become more complex, these decisions must account for performance, scalability, cost, reliability, and security.
In this course, we'll work through these challenges step by step. We'll build systems that retrieve information, use tools, process text, audio, and visual inputs, and connect with other application components. We'll also explore how to deploy, monitor, evaluate, and secure these systems, including how to handle failures and unexpected model behavior.
By the end of the course, you'll understand how the parts of an AI application fit together and how engineering decisions affect its operation in production.
Why take this course?
Modern AI development has moved beyond making basic API calls to constructing complete application systems. Today's applications must coordinate multi-step tasks, pull in context from various data sources, and operate within clear performance, cost, and security guidelines.
While base models are powerful, taking them to production introduces practical challenges:
Relevant information and accuracy: Standard prompts lack private domain knowledge, which can lead to incomplete or inaccurate outputs.
Tool and media workflows: Uncoordinated tool connections and combined audio or visual streams can cause timing issues, errors, or broken user experiences.
Latency and cost: Unoptimized pipelines can lead to slow response times, delayed playback, and higher operational expenses.
Security and privacy: Applications without defined boundaries are vulnerable to unexpected inputs, data leaks, and unauthorized access.
This course focuses on practical design choices, clean integrations, and deployment practices to solve these core engineering challenges.
What will you learn?
Here is an overview of what we'll cover across the course:
Core systems and information retrieval
To build reliable AI applications, we need strong foundations for fetching context and running tasks.
Combine keyword search with semantic search to pull accurate context.
Build multi-step agents that use tools reliably and operate within set boundaries.
Explore model selection, lightweight fine-tuning, and adaptation methods.
Deploy applications as reliable web services, using caching, usage limits, and automated tests to manage latency, cost, and quality.
Working with multiple media streams
Combining voice, text, and visual data requires managing input types, background coordination, and response speed.
Set clear data requirements for speech-to-text and text-to-speech features.
Balance bulk processing with real-time streaming to reduce initial audio playback delays.
Coordinate text, voice, and image capabilities into smooth workflows.
Keep user interfaces synced by using unique tracking IDs and reliable fallback behaviors when unexpected inputs occur.
Application security, privacy, and safeguards
Deploying AI systems requires proactive safeguards to protect user data and handle unexpected inputs.
Protect user privacy by identifying sensitive data, encrypting logs, and setting up automated data cleanup.
Turn general user feedback into specific, reproducible test cases with clear pass/fail criteria.
Set up pre-input checks, content filters, and live operational monitoring with emergency stop controls.
Who is this course for?
This course is designed for builders ready to move from initial experiments to working software:
