Once the basics are comfortable.

Build an agent from scratch, then rebuild it with LangGraph, adding search tools, persistence and human-in-the-loop steps.

DeepLearning.AI and LangChain

Use function calling and the LangChain Expression Language to build tool-using conversational agents.

DeepLearning.AI and LangChain

A free course that goes from agent fundamentals to building agents with smolagents, LlamaIndex and LangGraph, with a certificate.

Hugging Face

LangChain's free academy course on building controllable agent workflows with LangGraph: state, memory and human-in-the-loop.

LangChain Academy

Build agents that play Connect Four, starting with heuristics and minimax and moving on to reinforcement learning.

Kaggle

Design teams of role-playing AI agents that collaborate on research, writing and analysis tasks.

DeepLearning.AI and crewAI

Research-level depth and specialist material.

Train agents with Q-learning, policy gradients, PPO and more, and pit them against each other in game environments.
