This is a round-up of free Udemy courses covering AI agents, Hermes AI, Copilot, Claude, RAG, Azure, Python and networking topics such as CCNA. It sits alongside Udemy’s usual mix of short, skills-focused classes and competes with the free tiers you will find on platforms like Coursera, edX and YouTube, with the difference that Udemy courses often lean on practical demos and downloadable resources rather than formal assessment.
Who is this list best for?
Most useful if you like learning in small chunks and want to sample a topic before committing to a longer programme. AI tooling courses can help you understand current workflows (prompting, agent set-ups, retrieval augmented generation) while Azure and Kubernetes content is better suited if you already have some IT basics and want job-relevant context.
- AI and agents: good for seeing how modern assistants are wired into tools and data
- Cloud and DevOps: helpful if you want a clearer picture of Azure services and container workflows
- Python and networking: better when you want fundamentals that support everything else
