Microsoft Open-Source Generative AI Intro Course: 21 Lessons to Build AI Apps from Scratch

Microsoft Cloud Advocates have launched a free open-source introductory course on generative AI, covering 21 carefully designed modules from LLM basics to advanced topics like RAG, AI Agents, and fine-tuning. It supports dual-language code examples in Python and TypeScript, offers multilingual translation versions and active community support, helping developers systematically master generative AI application development skills.

• Original Author/Maintainer: Microsoft Cloud Advocates
• Source Platform: GitHub
• Original Title: Generative AI for Beginners (Version 3)

• Release Status: Continuously updated, currently Version 3

Against the backdrop of rapid development in AI technology, generative AI has become one of the core skills for developers, and this course provides a systematic learning path for beginners.

The course is designed around the core philosophy of "learning by doing", with each module divided into two categories: "Learning" (theory) and "Building" (practice). The 21 modules are arranged in a progressive knowledge sequence:

1. Basic Stage: Generative AI/LLM concepts, model selection, responsible AI, basic and advanced prompt engineering skills;
2. Practical Stage: Text generation, chatbots, vector database search, image generation, low-code AI applications;
3. Advanced Stage: Function calling, UX design, AI security, LLMOps;
4. Cutting-edge Stage: RAG, Hugging Face open-source models, AI Agents, LLM fine-tuning, SLM, Mistral/Meta model families.

• Multilingual Support: Supports translations in over 50 languages (including Simplified Chinese), with automatic synchronization to the original version via GitHub Actions;
• Community Support: Join the Azure AI Foundry Discord community for communication, or provide feedback via GitHub Issues/PRs;
• Technical Platform: Supports three runtime environments: Azure OpenAI Service, GitHub Marketplace Model Catalog, and OpenAI API;
• Programming Languages: Provides code examples in Python and TypeScript; .NET developers can choose the dedicated version;
• Teaching Format: Each module includes short videos, written tutorials, runnable code, and extended resources.

Completing the course allows you to master the full skill set for building production-grade AI applications: from Transformer architecture and prompt engineering to RAG systems, AI Agent development, and model fine-tuning. For engineers transitioning careers or integrating AI capabilities, the course content is authoritative and aligned with industry practices. Learning mainstream tech stacks like Azure OpenAI and GitHub Models can enhance your professional competitiveness.

The course uses the MIT license, allowing free use, modification, and distribution, and has an active community of contributors. Currently in Version 3, it adds cutting-edge topics like Small Language Models (SLM), Mistral model family, and Meta model family compared to earlier versions. Continuous iteration ensures the content keeps up with technological developments.

This course embodies Microsoft's commitment to AI democratization, providing high-quality free resources for developers worldwide. Whether you are an AI novice or an experienced developer, you can build a solid foundation and advance through this structured course. In an era of rapid AI development, continuous learning is crucial—we recommend starting your generative AI learning journey immediately.
