Getting Started with Stable Diffusion 3: What's New & How To Use It

Stability AI has just released a new and exciting tool called Stable Diffusion 3, which is a big step forward in using artificial intelligence to create images. Here's a simple and detailed explanation of what it's all about:

What is Stable Diffusion 3?

Stable Diffusion 3 is a super-smart computer program that can make pictures for you. It's like having a magic artist that can draw anything you can imagine. It's the newest and best version from Stability AI, and it's even better than the ones that came before it.

Detailed Technical Improvements

Enhanced Text Generation Capability

Stable Diffusion 3 has made significant strides in text rendering, capable of generating high-quality images containing long sentences, which was not possible with previous models.

Improved Prompt Following

Stable Diffusion 3 has significantly improved its adherence to user prompts through training with highly accurate image captions, matching the performance of DALL-E 3.

Speed and Deployment

Stable Diffusion 3 can be run locally on the largest model with a graphics card featuring 24 GB of RAM. Initial benchmark tests indicate that generating a 1024×1024 image (50 steps) on an RTX 4090 graphics card takes 34 seconds, suggesting substantial room for future optimization.


Stable Diffusion 3 is likely to generate only safe-for-work (SFW) images. Additionally, artists who do not wish their work to be included in the model have the option to opt out.

New Features of the Stable Diffusion 3 Model

Noise Predictor

A notable change in Stable Diffusion 3 is the shift away from the U-Net noise predictor architecture used in Stable Diffusion 1 and 2. Instead, it employs a repeating stack of Diffusion Transformers, which, like transformers in large language models, offer predictable performance improvements as the model size increases.


Stable Diffusion 3 utilizes Rectified Flow sampling, essentially a direct path from noise to a clear image—the most efficient route. The team also discovered a noise schedule that samples the middle part of the path more frequently, resulting in higher-quality images.

Text Encoders

Stable Diffusion 3 employs three text encoders, an increase from its predecessors:

  1. OpenAI’s CLIP L/14
  2. OpenCLIP bigG/14
  3. T5-v1.1-XXL (This larger encoder can be omitted if text generation is not required)

Better Captions

Stable Diffusion 3 also uses highly accurate captions during training, similar to DALL-E 3, which contributes to its strong prompt-following capabilities.

How to Download the Stable Diffusion 3 Model?

As Stable Diffusion 3 is not yet publicly available, you will need to join the waitlist to gain early access. Once the model is released, you will be able to access it through Stability AI's membership program, which is reasonably priced for small businesses.

How to Try Stable Diffusion 3 Early

Early Preview: In February 2024, Stability AI let some people start trying out Stable Diffusion 3 before everyone else. They did this to make sure it's as good as it can be when more people get to use it.

Join the Waitlist: If you want to try it out early, you can sign up on Stability AI's website. They'll let you know when you can start using it and give you a chance to help make it better by sharing what you think.

Public Release: We don't know exactly when Stable Diffusion 3 will be available for everyone, but Stability AI is making sure it's perfect before they let more people use it.

How It Works and What's New

How It's Built: Stable Diffusion 3 uses a special mix of two things: diffusion techniques and transformer models. Think of it like having the best parts of two different magic tricks to make even better pictures.

Different Sizes: There are different versions of Stable Diffusion 3, from small ones that are quick and easy to use, to huge ones that can make super detailed pictures. This means no matter what you're trying to create, there's a version that will work best for you.

New and Improved: Stable Diffusion 3 can understand even the most complicated ideas you have and turn them into pictures. It can also use both words and pictures to help make something new and amazing. Plus, it's gotten better at making everything look really, really good.

Who Can Use It and How

Stable Diffusion 3 is for everyone who loves to create things. People who make ads, design video games, plan buildings, or even teachers who want to make learning more fun can all use it. It's a tool that can help you bring your ideas to life in a whole new way.

How to Get Access

Announcement: Stability AI is really excited about their new tool and wants to make sure it's the best it can be. They're letting a small group of people try it out early to give feedback.

Free Trial: If you want to try Stable Diffusion 3 for yourself, you can go to and use for a free trial. This will let you play with the tool and see how it can help you make amazing pictures.


The launch of Stable Diffusion 3 not only provides artists and designers with powerful new tools but also opens up new application prospects for developers. With this guide, you should have a deeper understanding of Stable Diffusion 3. As the model is officially released and optimized, we can expect to see more innovation and breakthroughs in the field of text-to-image generation.
