Top 5 Free AI Courses: How to Master Neural Networks in a Weekend

Below is a selection of courses that will help you master AI tools in a single weekend.

Natural Language Processing with Deep Learning by Stanford University
This course is offered by one of the world’s leading technological universities. The program is designed for those who want to go beyond simply using chatbots and understand the architectural principles of large language models.

You will learn how to quickly fine-tune models for your specific tasks using SFT and LoRA methods, how to “compress” them via quantization for use on standard PCs, and how to apply RLHF and DPO techniques to ensure AI responses are accurate and concise.

A separate module focuses on creating AI agents. You will study the RAG technology, which allows neural networks to retrieve facts from your documents, and the ReAct method, which enables the model to “reason” first and then autonomously invoke the necessary programs.

Data Science and AI Principles by Harvard Online
A new offering for 2026, designed for those who need to understand AI capabilities without becoming developers. The course provides an overview of prediction systems, data visualization, and ethical considerations.

This course explains how data is transformed into AI products, the difference between supervised and unsupervised learning, and how organizations use LLMs to transform services. It is suitable for management and analysts. It teaches how to translate business tasks into data language, helping you understand where AI will truly generate profit and where its implementation would be excessive and costly.

Runway Academy
Runway is one of the leaders in the field of video AI. Its own academy offers free tutorials on working with Gen-2 and Gen-3 models.

This course covers creating videos from text descriptions, editing clips using AI, and professional video production for marketing. It is ideal for UX/UI designers and content creators who need to quickly integrate AI into their workflow.

Generative AI Studio by Google Cloud
Google provides access to introductory courses on generative AI. The program is designed for those who want to understand the technical “underpinnings” of neural networks without diving into complex mathematical code. In the course, you will learn about the basics of large language models, working with the Vertex AI platform, and the ethics of using artificial intelligence.

AI Fundamentals by Intel
A program from one of the world’s largest chip manufacturers. The course provides a systematic understanding of how data is transformed into AI solutions and what computing power is required for this. In the course, you will learn the difference between machine learning and deep learning, and get acquainted with computer vision and natural language processing. Upon completion, a certificate is issued that is recognized by the international IT community.
