What is DeepFloyd?
DeepFloyd is a research project by Stability AI. This company develops AI solutions for various domains like healthcare, education, and entertainment. DeepFloyd aims to create a new state-of-the-art in text-to-image synthesis, a challenging task that requires both high-level language understanding and low-level image generation.
DeepFloyd comprises three main components: a text encoder, a base model, and two super-resolution models. Let’s take a closer look at each of them.
The text encoder is responsible for extracting meaningful features from the input text. DeepFloyd uses a frozen text encoder based on the T5 transformer, a powerful natural language processing model that can perform multiple tasks such as translation, summarization, and question answering.
The text encoder takes the input text and encodes it into a fixed-length vector representation that captures its semantic and syntactic information. This vector is then fed into the next component, the base model.
Based on the text vector, the base model generates a low-resolution image (64×64 pixels). DeepFloyd uses a pixel diffusion model, a novel image generation technique that iteratively refines an image from noise using probabilistic modeling.
The base model consists of a UNet architecture, a convolutional neural network with an encoder-decoder structure with skip connections. The UNet is enhanced with cross-attention and attention-pooling modules, allowing the model to attend to the text vector and image features at different scales.
The base model produces a realistic and diverse image that matches the input text but at a low resolution. To improve the image quality, the next component comes into play: the super-resolution models.
The super-resolution models increase the image’s resolution generated by the base model. DeepFloyd uses two super-resolution models: one that upscales the image to 256×256 pixels and another that upscales it to 1024×1024 pixels.
The super-resolution models also use pixel diffusion models with UNet architectures, cross-attention, and attention-pooling modules. However, they are trained separately from the base model using different datasets and loss functions. This allows them to focus on enhancing the details and textures of the image without changing its content or style.
The super-resolution models produce high-quality images that are sharp, clear, and realistic. They also preserve the diversity and creativity of the base model, resulting in stunning images that can impress anyone.

How to Use DeepFloyd?
DeepFloyd is available on Hugging Face, the AI community platform that hosts thousands of pre-trained models for various tasks. You can access DeepFloyd’s models by visiting their profile page on Hugging Face.
To use DeepFloyd’s models, you must first accept their usage conditions. You can do this by creating a Hugging Face account (if you don’t have one already) and logging in. Then, you must accept the license on each model card by clicking the “Accept” button.
Once you have accepted the license, you can use DeepFloyd’s models in different ways:
- You can use their online demo to generate images from text prompts interactively. You can choose from Dream, Style Transfer, Super Resolution, or Inpainting modes. You can also adjust some parameters, such as temperature or truncation, to control the randomness and diversity of the generated images.
- You can use their Jupyter notebooks to generate images from text prompts programmatically. You can install their Python package deepfloyd_if and import their models using huggingface_hub. You can also customize the image generation process using different stages of their cascaded diffusion models.
- You can use their Diffusers library to generate images from text prompts using Hugging Face’s inference API. Diffuser is a library that wraps around DeepFloyd’s models and provides an easy-to-use interface for text-to-image synthesis. Using a single line of code, you can use Diffusers to generate images from text prompts.

Why is DeepFloyd Important?
DeepFloyd is an important contribution to the field of text-to-image synthesis for several reasons:
- It achieves a new state-of-the-art in terms of photorealism and language understanding. DeepFloyd outperforms previous models such as DALL-E, VQGAN, and CLIP on the COCO dataset, a benchmark for text-to-image synthesis. DeepFloyd achieves a zero-shot FID score of 6.66, which measures the similarity and diversity of the generated images compared to the real ones.
- It introduces a novel architecture that combines pixel diffusion models with UNet architectures, cross-attention, and attention-pooling modules. DeepFloyd shows that larger UNet architectures in the first stage of cascaded diffusion models can significantly improve image quality and diversity. DeepFloyd also shows that cross-attention and attention-pooling modules can enhance the model’s language understanding and image generation capabilities.
- It provides an open-source and research-permissible model that other researchers and enthusiasts can use. DeepFloyd releases its models on a non-commercial, research-permissible license that allows anyone to examine and experiment with their approach. DeepFloyd also provides various tools and resources to make their models accessible and easy to use.
