Understanding LLMs: GenAI, RAG & Prompting Fundamentals

Unlock the potential of generative AI and LLMs with practical lessons on image generation, transformers, prompt engineering, and RAG. Learn how to refine prompts for real-world success in AI projects. This course introduces learners to generative AI, large language models (LLMs), and retrieval-augmented generation (RAG). Beginning with foundational AI concepts and practical applications, participants explore how generative AI tools like ChatGPT, Gemini, and Midjourney produce high-quality images and videos. The course then dives into the mechanics of transformers, helping learners understand how LLMs generate and process language. Focusing on practical techniques, students will master prompt engineering, including zero-shot and few-shot prompting, and learn how to evaluate and optimize AI models. Case studies provide real-world insights into refining prompts for different scenarios. The course also covers multimodal models and the transformative power of RAG in enhancing AI's capabilities. By the end, learners will be proficient in using LLMs, designing optimized prompts, and exploring cutting-edge applications of generative AI, making this course essential for professionals looking to leverage AI in real-world projects. This course is designed for technical professionals, AI enthusiasts, and individuals eager to dive into the rapidly evolving world of generative AI and LLMs. It's ideal for software developers, data scientists, machine learning engineers, and anyone interested in AI applications. No prior knowledge of AI is required, but a basic understanding of programming and machine learning concepts will be helpful. Participants should be motivated to learn practical skills for applying generative AI and prompt engineering in real-world scenarios. This course takes you on a comprehensive journey from foundational AI concepts to advanced applications. You'll dive into generative AI technologies, understand how large language models (LLMs) work, and master practical techniques like prompt engineering, all while exploring their real-world applications.
