Quick Start 2024: Stable Diffusion for Superior AI Imagery

Intrigued by how AI models breathe life into static text, transforming them into vivid visuals? Meet "Stable Diffusion," an innovative AI model making waves in image generation. This guide takes you on a journey through the inner workings of Stable Diffusion and introduces AI tools that utilize this model to create stunning images. Ready to unlock the potential of AI in image creation? Let's get started!

1. Introduction to Stable Diffusion Model


The Stable Diffusion model, an advanced deep generative neural network, was conceptualized and brought into existence by a collaborative effort from the CompVis Group at Ludwig Maximilian University of Munich, Runway, and Stability AI. This model, released in 2022, operates under the principles of diffusion models, a class of models used in deep learning to generate new data that resembles the provided training data.

The core concept that drives this model is diffusion, akin to its namesake process in physics, which involves the spreading or dispersion of particles. In the context of Stable Diffusion, the image undergoes diffusion: transforming from an initial state to a final state through a series of small, incremental changes. The model, therefore, begins with a target image, applies random noise or perturbations, and gradually evolves the image from its original state to a final state, producing high-quality, photorealistic images conditioned on text inputs.

Stability AI, acknowledged for making Stable Diffusion an open-source image generator in August 2022, uses it as a competitor against existing image generators such as OpenAI's Dall-E and MidJourney. The unique selling point of Stable Diffusion in this competition is its status as an open-source model. Its code and model weights are publicly available, making it easily accessible to anyone equipped with basic GPU consumer hardware, given it has a minimum of 8 GB VRAM.

Key features 

The deployment of Stable Diffusion involved a cross-disciplinary effort from the legal, ethics, and technology teams at HuggingFace and the engineers at CoreWeave. Key features include:

i) The model is available under a Creative ML OpenRAIL-M license, a flexible license permitting both commercial and non-commercial uses. The license highlights the ethical and legal responsibilities associated with the model's usefulness.

ii) The model also includes an AI-based Safety Classifier as part of its package. This classifier understands concepts in generated images and prevents the production of potentially unwanted outputs. It allows user-driven parameter adjustments to fine-tune the model's performance.

The model's training data comes from the 2b English language label subset of LAION 5b, a substantial internet crawl created by the German charity LAION.

Hence, Stable Diffusion can foster creativity in generating impressive visual imagery.  

2. Capabilities of Stable Diffusion

Stable Diffusion exhibits a range of robust capabilities, mainly hinging on its adeptness at handling text prompts.

Image Generation: 

Stable Diffusion is proficient in crafting brand-new images from scratch. The model can generate images according to textual cues, including which components to incorporate or exclude.

Guided Image Synthesis: 

Beyond creating images, Stable Diffusion can also re-sketch existing images to incorporate new elements dictated by a text prompt. 

For example, you can upload a picture of the sky with a text instruction: "Add some clouds and birds to this picture." This feature, also known as "guided image synthesis," is supported by the model's diffusion denoising mechanism.

Image Alteration: 

Stable Diffusion can partially modify existing images by applying inpainting and outpainting techniques. This is executed in response to text prompts. To use this functionality, you need a user interface that supports such functionality and several open-source implementations that are readily available. The good news is that some AI image creators have already implemented this, allowing users to edit the images that have been generated.

Overall, Stable Diffusion goes beyond simply generating images, demonstrating a versatile capacity to synthesize, alter, and recreate images based on user-guided textual prompts.

3. How Stable Diffusion Model Works in Image Creation

The Stable Diffusion model works by starting with a target image and then applying a series of random perturbations or 'noise' to it. This noise is carefully calibrated so that it spreads or 'diffuses' across the image in a controlled manner. Over time, these random perturbations cause the image to evolve or 'diffuse' from its initial state to a final state that is a plausible sample from the data distribution. The process is reversed during sampling: starting with noise and progressively removing it to generate the final image.

"Stable" means that the model's diffusion process is stable so that the image generation results do not appear chaotic and distorted. The amount and nature of the noise applied at each step must be carefully controlled to achieve this.

You can apply Stable Diffusion Model in two ways:

  1. AI Image Creators that use Stable Diffusion Model: Several AI image generators online use Stable Diffusion Model. You usually input some prompts or initial images, and the AI will apply the diffusion process to generate a new image. Some platforms require a subscription or payment to access, while others are free to use.

  2. Downloading Stable Diffusion on Your Computer: Another way is to install stable diffusion directly on your computer. This method involves many steps. Also, rather than using the image generator directly, you may need to train the model on an image dataset before using it to generate images. Training is typically done by feeding the model many images for it to learn the patterns and mechanisms. The time required for training is variable, but it usually takes a long time and requires high computer functions and configurations.

Next, we will introduce these two methods in detail.

6. Limitations of Stable Diffusion

Despite its impressive capabilities, Stable Diffusion exhibits shortcomings that may influence its efficiency and effectiveness.

Image Quality and Resolution: 

The model was initially trained on a dataset comprising images of 512x512 resolution. As a result, image quality noticeably degrades if user specifications deviate from this resolution. However, a subsequent update (version 2.0) has improved the native image generation resolution to 768x768.

Human Limb and Face Generation: 

Another challenging area to generate stable diffusion results is human limbs and faces. Due to the poor representation of these features in the LAION database used to train the model, Stable Diffusion is prone to significant inaccuracies when dealing with prompts related to human limbs and facial images.

Inability to Achieve Perfect Photorealism: 

Although Stable Diffusion can generate impressively realistic images, it falls short of perfect photorealism. 

Stable Diffusion still has room for improvement in terms of image realism, although its current generation results are already impressive. This photorealistic imperfection also has implications for completing more compositional prompts, potentially causing the model to underperform when handling such instructions.

For example: let's use "green cube on top of red sphere" as the prompt.

Stable Diffusion Online:

Midjourney Green Cube On Top Of Red Sphere

Algorithmic Bias: 

An inherent limitation of Stable Diffusion lies in its algorithmic bias. The model was primarily trained on images accompanied by English descriptions, leading to an inherent Western bias in the generated images. Consequently, prompts in languages other than English are likely to yield less accurate results, with Western or white cultures often being the default representation.

Data Loss and Memorization: 

The model’s autoencoding mechanism is lossy, which can degrade image quality. Moreover, no measures were taken to deduplicate the dataset during training, leading to the potential memorization of duplicated images.

Safety Considerations: 

The model was trained on the large-scale dataset LAION-5B, which contains adult material. As a result, the model may not be suitable for product use without additional safety mechanisms and considerations.

These limitations underline the need for further improvements in Stable Diffusion to ensure it can handle a broader range of tasks while mitigating biases and enhancing data safety. 

7. Comparison: Midjourney vs. Stable Diffusion (consider using a table here)

Here's a summarized comparison between Midjourney and Stable Diffusion, two popular AI image generators:
