Learning artificial intelligence as a newcomer often begins with a simple question: where to start? AI now encompasses more than just machine learning models. Beginners encounter Generative AI, prompt engineering, neural networks, Python, AI agents, RAG, computer vision, and large language models. Trying to learn everything at once can lead to more confusion than progress.
A better approach is to build skills in layers. Start with the fundamentals, understand how AI can solve real problems, develop technical knowledge, explore newer areas like Generative AI and agentic AI, and then apply these concepts through projects.
Below are some free AI courses that cover different aspects of this skill set.
