Stable Diffusion Vs latent diffusion

Share this article

In the dynamic realm of technology, artificial intelligence (AI) and machine learning (ML) have emerged as key players in the art industry, birthing groundbreaking tools like Stable Diffusion and Latent Diffusion models. However, many users want a showdown between Stable Diffusion vs Latent Diffusion.

This article presents an elaborate discussion of these two types of diffusion, their workings, differences, and future implications.

Understanding Stable Diffusion

Stable Diffusion Public Release — Stability AI

Image generated via Stable Diffusion

Stable Diffusion is a model used for generating virtual creations through AI. It stands apart from other models due to its open-source nature, meaning anyone can access and analyze its code.

Stable Diffusion employs a frozen CLIP ViT-L/14 text encoder, enabling it to generate images based on text prompts. Additionally, the model operates through a process known as “diffusion.” It begins only with noise and gradually improves an image until there is no noise left, thus bringing the image much closer to the provided text description.

Moreover, are you wondering if Midjourney makes use of Stable Diffusion? Uncover the answers in our blog.

Delving into Latent Diffusion

On the other hand, Latent Diffusion is another text-to-image model that produces impressive images based on text prompts. It was developed by CompVis and trained on the LAION-100M dataset.

However, one must note that the model outputs content that reinforces or exacerbates societal biases. Moreover, the deep learning (DL) modules in Latent Diffusion typically produce or exacerbate biases that are already present within the data.

Stable Diffusion vs Latent Diffusion: A comparative analysis

Stable Diffusion and Latent Diffusion are both probabilistic generative models used in machine learning and deep learning for tasks like image generation and data synthesis. They have some key differences that set them apart. 

Here is a showdown between Stable Diffusion vs Latent Diffusion:

1. Stable Diffusion vs Latent Diffusion: Objective function

Stable Diffusion: Stable Diffusion uses a learned energy-based model (EBM) to estimate the likelihood of generated samples. It minimizes the Kullback-Leibler (KL) divergence between the model’s and target distribution, often chosen as a Gaussian distribution.

Latent Diffusion: Latent Diffusion directly models the data likelihood by estimating the conditional distribution of data given noise vectors. It minimizes the negative log-likelihood of the data, which is similar to maximum likelihood estimation.

2. Stable Diffusion vs Latent Diffusion: Modeling strategy

Stable Diffusion: Stable Diffusion focuses on modeling the energy or density of the data distribution. Adding noise uses a diffusion process to gradually transition from a simple distribution (e.g., Gaussian) to the data distribution.

Latent Diffusion: Latent Diffusion models the data likelihood in the latent space by sequentially updating the latent variables using a diffusion process. It learns the evolution of the latent variables to match the data distribution.

3. Stable Diffusion vs Latent Diffusion: Noise handling

Stable Diffusion: Stable Diffusion adds noise directly to the data during training, gradually increasing the noise level to match the complexity of the data distribution.

Latent Diffusion: Latent Diffusion applies noise to the latent variables and uses a diffusion process in the latent space. This means the noise is injected before the data is generated.

4.  Stable Diffusion vs Latent Diffusion: Sampling strategy

Stable Diffusion: In Stable Diffusion, the sampling process involves iteratively updating the generated data with noise and gradually reducing the noise level until a sample is generated.

Latent Diffusion: Latent Diffusion involves sampling noise vectors in the latent space and updating them iteratively to generate data samples.

5.  Stable Diffusion vs Latent Diffusion: Use cases

Stable Diffusion: Stable Diffusion is often used for tasks like image synthesis and data generation, where the focus is on capturing high-dimensional data distributions and generating high-quality samples.

Latent Diffusion: Latent Diffusion is primarily used for density estimation and likelihood-based generative modeling. It is particularly useful when the likelihood of the data is the main concern, such as in density ratio estimation and likelihood-based anomaly detection.

In summary, Stable Diffusion and Latent Diffusion differ in their objective functions, modeling strategies, noise handling, sampling strategies, and use cases. Moreover, the choice between them depends on the specific goals of the generative modeling task at hand.

Implications of AI-generated art

The implications of these AI models on the art industry are immense. Some artists and creators argue in favor of unrestricted access to image generation, as it allows them to create artworks that might have been nearly impossible for them given their skill level.

However, others argue that AI could harm the art industry, as generators are becoming so good that differentiating a real hand-drawn digital artwork from one generated by AI is becoming increasingly difficult.

Limitations of these models

Despite the advancements in AI-generated art, these models have their limitations. Take a look at them:

  • Lack of creativity: AI art generators can create images that are visually appealing, but they often lack the creativity and originality of human-created art.
  • Bias: AI art generators are trained on large datasets of images, which can reflect the biases that exist in the real world. This means that AI art generators can produce images that are sexist, racist, or otherwise discriminatory.
  • Copyright infringement: AI art generators can be used to create images that are based on copyrighted works. This can lead to copyright infringement claims.
  • Lack of control: Artists have little control over the images that are created by AI art generators. This can lead to frustration and dissatisfaction.
  • Technical limitations: AI art generators are still under development, and they can sometimes produce images that are blurry, unrealistic, or otherwise flawed.

Overall, AI art generators are powerful tools that create visually appealing images. However, it is important to be aware of their limitations before using them.

In the labyrinth of the digital cosmos, let’s journey down the constellation of AI image-generation tools that will illuminate your creative path.

Summing up

In the final showdown of Stable Diffusion vs Latent diffusion, it is evident that both the models have strengths and weaknesses. Stable Diffusion is faster and generates more complex images.

In contrast, Latent Diffusion is more suited for research purposes due to the biases it introduces. Moreover, as AI continues to evolve, we can expect these models to improve and become even more efficient in generating high-quality images.
