About this course

Curious about how AI can perform tasks on its own? This course demystifies the world of AI agents and gives you the foundational skills to build them from scratch, even with no prior experience in AI. You will go from understanding the basic theory behind Large Language Models (LLMs) and agentic workflows to writing your first functional AI agent in Python. This course focuses on core principles, enabling you to design simple agents that can reason, plan, and use tools to accomplish goals. What you'll learn: - Understand the core concepts of AI agents, including planning, memory, and tool use - Learn fundamental prompt engineering techniques to guide agent behavior - Build a simple AI agent using Python and popular open-source libraries - Implement basic Retrieval-Augmented Generation (RAG) to give your agent access to external knowledge - Practice defining and integrating custom tools for your agents to interact with external systems - Set up a modern Python development environment for your AI projects The course starts with the essential terminology and architecture of AI agents before guiding you through hands-on exercises to build your own. You will learn by reading clear explanations and applying concepts in practical coding tasks. This course is designed for absolute beginners. No prior experience in AI or machine learning is required, though a basic familiarity with Python will be helpful to complete the exercises. Start your journey into the exciting field of autonomous AI today.

Eindelijk snap ik hoe AI-agents tools gebruiken.

الكورس شرح فكرة الوكلاء الذكية بطريقة سهلة جدًا، من كتابة الأوامر الأولية إلى ربط الأداة الفعلية اللي يقدر الوكيل يستخدمها لتنفيذ مهمة حقيقية. أكثر جزء أعجبني كان لما شفت الوكيل يقرر بنفسه متى يستدعي الأداة بدل ما يكون مجرد رد نصي عادي. خلصت الكورس وعندي أول agent شغال فعليًا، وحسيت بإنجاز حقيقي.

Наконец понял, как агент выбирает нужный инструмент.

AIエージェントがどうやってツールを選んで実行するのか、仕組みがようやく理解できました。特にプロンプトの組み立て方の説明がわかりやすかったです。ただエラー処理の部分はもう少し具体例が欲しかったです。

ปกติผมใช้ AI แค่ถามตอบทั่วไป ไม่เคยรู้เลยว่าการสร้าง agent ที่เรียกใช้เครื่องมือเองได้มันทำงานยังไง คอร์สนี้อธิบายตั้งแต่พื้นฐานของการเขียน prompt ไปจนถึงการต่อ tool ให้ agent ใช้งานจริง เข้าใจง่ายกว่าที่คิดไว้มาก ส่วนที่รู้สึกว่ายังไม่ค่อยลงลึกคือตอนจัดการ error เวลา agent ทำงานผิดพลาด แต่โดยรวมพอเรียนจบก็สร้าง agent ตัวแรกของตัวเองได้จริงและรู้สึกภูมิใจไม่น้อย

Solide Einführung, nur das Debugging war knapp.

I've dabbled with AI tools before but never actually understood how an agent decides which tool to call and when, and this course finally made that click. The breakdown of prompt engineering specifically for agent behavior, rather than just chat responses, was the most valuable part for me. Watching the instructor walk through a failed tool call and explain why the agent got confused taught me more than any of the successful examples did. By the end I had built a small agent that could actually complete a multi-step task on its own, which felt like a genuine milestone. I'd already started sketching ideas for a second, more complex agent before I even finished the last lesson.

Enfin compris comment un agent choisit ses outils.

I went into this course with almost no background in agent-based systems, just some basic prompting experience from using chatbots casually. The early lessons on how an agent plans out steps before acting were surprisingly clear, breaking down something that sounded abstract into a process I could actually follow. Connecting a tool for the first time and watching the agent decide on its own when to call it was honestly a bit of a wow moment. My only complaint is that the final project felt a little open-ended without much guidance on how to structure a more complex agent from scratch. That said, I now feel like I could keep building on what I made instead of just closing the course and forgetting about it.

পাইথন মোটামুটি জানতাম, কিন্তু এআই এজেন্ট জিনিসটা কীভাবে কাজ করে তা নিয়ে সবসময় ধোঁয়াশায় ছিলাম। এই কোর্স এজেন্টের লুপ আর টুল ব্যবহারের ধারণাটা একদম পরিষ্কার করে বুঝিয়ে দিয়েছে। নিজের হাতে প্রথম একটা ছোট এজেন্ট বানানোর অংশটা সবচেয়ে ভালো লেগেছে, কারণ কোডটা সাথে সাথেই চলেছে। প্রম্পট ইঞ্জিনিয়ারিংয়ের অধ্যায়টা আরেকটু গভীর হলে ভালো হতো বলে মনে হয়েছে। তবু একজন শুরুর দিকের ডেভেলপার হিসেবে এটা দারুণ একটা সূচনা ছিল।

Kurs dobrze tłumaczy podstawy budowania agenta AI, od projektowania promptów po podpinanie narzędzi, którymi agent może się posługiwać. Trochę zabrakło mi głębszego wytłumaczenia obsługi błędów, gdy agent robi coś nieoczekiwanego. Mimo to po ukończeniu miałam działający, prosty projekt, co samo w sobie było satysfakcjonujące.

AI agent कैसे खुद decide करता है कि कब कौन सा tool इस्तेमाल करना है, यह समझाने का तरीका बहुत क्लियर था।

The hands-on project where you connect the agent to an actual external tool instead of just simulating it made the whole concept finally make sense.

Good breakdown of how an agent loops through reasoning and tool calls instead of just answering once. The middle section on error handling could use another example or two since that's where I got stuck longest. Still ended up with a working agent by the last lesson, which is more than I expected going in.

Penerangan tentang cara agent guna tool untuk buat kerja sebenar sangat jelas, cuma bahagian troubleshooting bila agent buat silap rasa agak ringkas.

Sinubukan ko itong kurso dahil gusto kong maintindihan kung paano talaga gumagana ang mga AI agent, hindi lang basta chatbot na sumasagot. Malinaw ang paliwanag tungkol sa prompt engineering at kung paano ikonekta ang agent sa mga tool para makagawa ng aktwal na aksyon. Medyo mabilis ang takbo sa bahagi ng debugging kaya kailangan kong i-rewind ilang beses para masundan. Sa huli, natapos ko ang sarili kong maliit na agent na nakakapagsagawa ng simpleng gawain, at proud ako dun.

Programuję w Pythonie od jakiegoś czasu, ale temat agentów AI zawsze wydawał mi się magią, dopóki nie trafiłem na ten kurs. Wreszcie zrozumiałem, na czym polega pętla agenta i jak podpiąć narzędzia, żeby model mógł sam wykonywać akcje. Najbardziej spodobało mi się budowanie pierwszego prostego agenta krok po kroku, bo wszystko działało od razu. Sekcja o projektowaniu promptów dla agentów rozjaśniła mi wiele rzeczy, których nie ogarniałem z dokumentacji. Po zajęciach od razu zacząłem pisać własnego asystenta do zadań. Świetne wprowadzenie dla kogoś, kto zna podstawy kodu.
