Artificial intelligence (AI) is one of the most exciting and impactful fields of technology today. AI is enabling new applications and possibilities across various domains and industries, such as healthcare, education, entertainment, and more. AI is also advancing the frontiers of human creativity and expression, by allowing us to generate novel and realistic content from data or prompts.
One of the most fascinating and challenging tasks in AI is natural language generation (NLG), the task of creating coherent and meaningful texts from data or prompts. NLG has many applications, such as summarizing information, writing captions, generating headlines, and more. But one of the most impressive and creative applications of NLG is generating images from text descriptions. Imagine being able to create any image you can think of, just by typing in a few words. For example, you could type in “a cat wearing a hat” and get an image of a cat wearing a hat.
This may sound like science fiction, but it is actually possible thanks to three groundbreaking AI models: DALL-E, Midjourney AI and Stable Diffusion. These models can generate realistic and diverse images from text descriptions, demonstrating a high degree of creativity and flexibility. But how do these models work, and which one is better? In this blog, we will compare DALL-E, Midjourney AI and Stable Diffusion, and show you how you can use them to create your own images with ILLA CLOUD.
DALL-E is an AI model that was introduced by OpenAI earlier this year. DALL-E is a variant of GPT-3, a large-scale language model that can generate texts on almost any topic given a prompt. DALL-E extends the capabilities of GPT-3 by enabling it to generate images from text descriptions, such as “an armchair in the shape of an avocado” or “a snail made of a harp”. DALL-E can produce multiple images for each prompt, demonstrating a high degree of creativity and flexibility.
DALL-E uses a neural network architecture called Transformer, which consists of layers of attention mechanisms that learn to encode and decode sequences of data. DALL-E uses a single Transformer model that can process both text and image tokens as inputs and outputs. DALL-E also uses a technique called VQ-VAE to compress high-resolution images into discrete tokens that can be fed into the Transformer model.
DALL-E can generate images at 64x64 pixels resolution, which is relatively low compared to other image generation models. However, DALL-E can still produce impressive results that capture the essence and details of the text descriptions. DALL-E can also handle complex and abstract concepts, such as “a painting of a capybara sitting in a field at sunrise” or “a diagram explaining how DALL-E works”.
Midjourney AI is an AI model that was developed by an independent research lab called Midjourney Lab. Midjourney AI is also a variant of GPT-3, but it uses a different approach to generate images from text descriptions. Midjourney AI uses a technique called CLIP to guide the image generation process.
CLIP is another AI model that was introduced by OpenAI earlier this year. CLIP stands for Contrastive Language-Image Pre-training, and it is a model that can learn to associate texts and images across different domains and tasks. CLIP can perform various image-related tasks, such as classification, captioning, retrieval, and more.
Midjourney AI uses CLIP as a feedback mechanism to optimize the image generation process. Midjourney AI starts with a random noise image and then iteratively modifies it until it matches the text description as closely as possible according to CLIP’s evaluation. Midjourney AI also uses another technique called StyleGAN2 to inject style and diversity into the generated images.
Midjourney AI can generate images at 256x256 pixels resolution, which is higher than DALL-E’s resolution. Midjourney AI can also produce realistic and diverse images that reflect the style and mood of the text descriptions. Midjourney AI excels at generating artistic and expressive images, such as “a portrait of Frida Kahlo with flowers in her hair” or “a surreal landscape with floating islands”.
Stable Diffusion is an AI model that was developed by Stability ai, a startup that focuses on building and sharing state-of-the-art natural language technologies. Stable Diffusion is based on two breakthroughs in generative modeling: diffusion models and DALL-E. Stable Diffusion combines these two techniques to create a model that can generate images from text descriptions using diffusion models instead of GPT-3.
Diffusion models are a class of generative models that learn to reverse a stochastic process that gradually corrupts an image or a text until it becomes pure noise. By reversing this process, diffusion models can generate high-quality samples from noise by applying a series of learned denoising steps. Diffusion models have been shown to outperform other generative models such as GANs and VAEs in terms of fidelity and diversity.
Stable Diffusion uses a diffusion model that is trained on a large dataset of images and their corresponding text descriptions, which are obtained from DALL-E. Stable Diffusion uses the same text encoder as DALL-E to encode the text descriptions into latent vectors, which are then used to condition the diffusion model. Stable Diffusion also uses a technique called annealed sampling to improve the quality and diversity of the generated images.
Stable Diffusion can generate images at 256x256 pixels resolution, which is higher than DALL-E’s resolution. Stable Diffusion can also generate more diverse and realistic images by leveraging the strengths of diffusion models. Stable Diffusion can handle various types of text descriptions, such as “a photo of a dog wearing sunglasses” or “a sketch of a dragon breathing fire”.
Now that we have introduced the three models, how can we compare them and decide which one is better? Well, there is no definitive answer to this question, as each model has its own strengths and weaknesses, and different use cases and preferences. However, we can use some criteria to evaluate and compare them, such as:
Resolution: This refers to the size and quality of the generated images. Higher resolution means more details and clarity. Among the three models, Midjourney AI and Stable Diffusion have higher resolution than DALL-E.
Diversity: This refers to the variety and uniqueness of the generated images. Higher diversity means more options and creativity. Among the three models, Stable Diffusion and Midjourney AI have higher diversity than DALL-E.
Realism: This refers to the degree of similarity between the generated images and real-world images. Higher realism means more accuracy and plausibility. Among the three models, Midjourney AI and DALL-E have higher realism than Stable Diffusion.
Style: This refers to the aesthetic and artistic aspects of the generated images. Higher style means more expression and mood. Among the three models, Midjourney AI has higher style than DALL-E and Stable Diffusion.
Speed: This refers to the time and resources required to generate images. Higher speed means more efficiency and convenience. Among the three models, DALL-E has higher speed than Midjourney AI and Stable Diffusion.
Based on these criteria, we can see that each model has its own advantages and disadvantages, depending on what you are looking for. For example, if you want high-resolution, diverse and realistic images, you might prefer Midjourney AI or Stable Diffusion over DALL-E. If you want fast and simple image generation, you might prefer DALL-E over Midjourney AI or Stable Diffusion. If you want artistic and expressive images, you might prefer Midjourney AI over DALL-E or Stable Diffusion.
Of course, these criteria are not exhaustive or objective, and you might have other factors or preferences that influence your choice. The best way to compare these models is to try them out yourself and see which one suits your needs and tastes better.
