From the creators of Openjourney

Create custom
AI models & LoRas
by fine-tuning
Stable Diffusion to your own images

Learn how to train your own models to replicate any style or subject, including artists and photorealism. On top of it, you'll learn what Dreambooth is and how to use it, for example, to make your own AI avatars. We'll cover important training techniques like LoRa and Textual Inversion that you'll use to create your own fine-tuned models. Build photorealistic models that will leave everyone speechless by generating images no one will be able tell apart from real pics.

Create your own styles. Learn how to train your own models, like Openjourney.

Here at PromptHero we created Openjourney, an open-source custom model that generates images in the style of Midjourney. People love it, and it has been downloaded millions of times already since it launched. Want to know how we made it? We'll tell all our secrets in this course.

Learn advanced techniques like Textual Inversion and LoRa.

Create characters and styles you can just drop-in in your images. We'll guide you through another custom model we made: Fashion Diffusion, a fine-tuned model we created trained on fashion imagery.

Stable Diffusion can only do so much.
Now take it to the next level.

Don't get us wrong – Stable Diffusion is a great generalistic model. It can create good enough images of almost everything – but it fails at certain tasks like creating photorealistic images, particularly humans. To make realistic-looking images of any kind, you need to train it for it.

None of these images are real or edited. They have all been created by AI using the techniques we cover in depth in this course.

Learn Dreambooth

Dreambooth is a technique used to train Stable Diffusion to learn to draw new things (like your face, your dog or even your backpack!) You feed it a few images of what you want it to learn, and it learns to generate images of that particular thing. To use it well and achieve good results, you'll need specific know-how – which we'll be covering in this course.

Learn to create your own AI avatars

Just so you get an idea of what you can end up doing, Dreambooth is the technology behind AI avatar craze. If you've seen people using any kind of app to generate an AI avatar of themselves, Dreambooth was the underlying technique across all apps. And yes, rest assured you'll be generating your own AI avatars in this course, too! (for free!)

Supercharge your AI workflow.
Get AI superpowers.

Get immediately differentiated

Stop using Stable Diffusion – everyone else is using it. Create your own secret sauce and build a model only you have access to.

Repurpose Stable Diffusion

Move from generalistic images to industry-specific images. Generate the perfect images for architecture, design, arts, videogames...

Future-proof and 10x what you can do with AI

Break free from the chains imposed by Stable Diffusion. Make AI do anything you can do. The only limit is your creativity and imagination.

Who is this for?

We have all types of people join, from hobby artists to renowned creative professionals in industries like interior design, architecture, photography and writing.


If you come from an artistic background, you'll find this course highly interesting. Painters, game makers, digital artists... master AI generation and take your art to the next level.


If you're a designer (fashion, graphic...), a copywriter or do any other sort of creative job, you'll find in AI fine tuning the perfect skill to get your work differentiated from the competition.


Architects, interior designers and photographers are already incorporating AI generated images into their workflow to provide clients with breathtaking results that no one else can give.

It's highly recommended that you've taken our crash course in generative AI before taking this advanced course. We'll assume you have a solid understanding of basic concepts in generative AI and common prompting tools like A1111.

It's not strictly necessary to have any coding experience or knowledge before enrolling. While we'll get quite technical, we'll make it easy to understand so you can follow along effortlessly. However, some familiarity with programming is highly recommended, as we'll make extensive use of code through the course. You'll be learning bleeding-edge techniques, and these are only available through code. If you're brave enough not to run away when you see a few lines of code on the screen, you'll have a lot of fun!
