There are 4 modules in this course

The Fine-Tuning Image Models with Diffusion course is designed for developers, engineers, and technical product builders who are new to Generative AI but already have intermediate machine learning knowledge, basic Python proficiency, and familiarity with development environments such as VS Code, and who want to engineer, customize, and deploy open generative AI solutions while avoiding vendor lock-in.

The course gives learners hands-on experience adapting generative image models for custom styles and applications. The course begins with the foundations of diffusion models, explaining forward and reverse diffusion processes and exploring the key components of Stable Diffusion architectures, including U-Net, VAE, and text encoders. Learners then apply Low-Rank Adaptation (LoRA) techniques to train efficiently on consumer hardware, comparing performance and trade-offs with full fine-tuning. In the second module, learners implement DreamBooth, a methodology for training on limited datasets to personalize models with custom concepts and artistic styles. Learners practice dataset preparation, hyperparameter tuning, and checkpoint management while preserving model generalization. The third module introduces ComfyUI, where learners design and execute node-based workflows that integrate fine-tuned models with advanced extensions like ControlNet. And, in the final module, learners will optimize fine-tuned diffusion models for production by systematically adjusting inference parameters to achieve optimal trade-offs between image quality, generation speed, and resource efficiency. By the end of the course, learners will have produced a custom fine-tuned diffusion model, integrated it into ComfyUI pipelines, and optimized it for production-quality image generation.

Learn the fundamentals of diffusion models and why they play such a critical role in modern image generation. You’ll explore the key architectural components of Stable Diffusion, U-Net, VAE, and text encoders, and see how LoRA adapts these models efficiently for fine-tuning. You’ll also analyze memory optimization techniques and compare LoRA with full fine-tuning approaches, giving you practical principles for deciding which method to use depending on your goals and constraints.

Frequently asked questions

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you enroll in the course, you get access to all of the courses in the Certificate, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
