What are the best tutorials for beginners to learn AI agents?
Where to start
The best beginner tutorials are the official quickstarts from OpenAI, Anthropic, and LangChain. They walk you through setting up an API key, making your first call, and adding tools. These are free and updated regularly.
YouTube channels like freeCodeCamp, sentdex, and AI Jason offer step-by-step video tutorials. Look for ones published in the last 6–12 months, since the field moves fast. Many use Python, but JavaScript options exist too.
- OpenAI API quickstart guide
- Anthropic's Claude tool-use tutorial
- LangChain's 'Build a simple agent' notebook
- freeCodeCamp's 'AI Agents for Beginners' video
- DeepLearning.AI's short courses (some free)
Hands-on projects
After the basics, build a few tiny agents. A weather bot that calls an API, a calculator agent that uses a tool, and a document Q&A bot that reads a PDF. Each teaches a core concept: tool use, memory, and retrieval.
Don't worry about using the fanciest framework. You can build all three with plain Python and an LLM API. The goal is to understand the loop: user input → LLM decides action → tool runs → result goes back to LLM.
Common mistakes
- Trying to learn every framework at once instead of mastering one simple agent first.
- Following outdated tutorials that use deprecated APIs or old model names.
- Skipping the fundamentals of API calls and tool use by jumping straight to complex multi-agent systems.
