DeepFloyd IF is a revolutionary text-to-image model that has been making waves in the AI community. It is an open-source version of Google’s Imagen, which was recently demonstrated to outperform OpenAI’s DALL-E 2 in terms of accuracy and quality of text-to-image synthesis.
DeepFloyd IF is capable of generating text in images, a feature that no other open-source model has been able to do reliably.
One of the key advantages of DeepFloyd IF is its architecture, which is similar to that of Google’s Imagen.
It relies on two super-resolution models that bring the resolution of the images to 1,024 x 1,024 pixels, and offers different model sizes with up to 4.3 billion parameters.
In tests, it even outperforms Google Imagen, achieving a Zero-Shot FID score of 6.66 on the COCO dataset, ahead of other available models such as Stable Diffusion.
However, there are also some limitations to DeepFloyd IF. For the largest model with an upscaler to 1,024 pixels, the team recommends 24 gigabytes of VRAM, which may not be feasible for some users.
Additionally, the first version of the IF model is subject to a restricted license, intended for research purposes only.
| Feature | Description |
|---|---|
| Architecture | Similar to Google’s Imagen |
| Super-resolution models | Bring resolution to 1,024 x 1,024 pixels |
| Model sizes | Offers different sizes with up to 4.3 billion parameters |
| Performance | Outperforms Google Imagen and other available models |

FAQ
DeepFloyd IF is a modular neural network based on the cascaded approach that generates high-resolution images in a cascading manner.
DeepFloyd IF is built with multiple neural modules that join forces within a single architecture to produce a synergistic effect. It uses diffusion models to introduce random noise into the data, before reversing the process to generate new data samples from the noise.
The IF-4.3B base model is the largest diffusion model in terms of the number of effective parameters of the U-Net. The IF-4.3B model achieves a state-of-the-art zero-shot FID score of 6.66, outperforming both Imagen and the diffusion model with expert denoisers eDiff-I.
A deep text understanding is achieved by employing a large language model T5-XXL as a text encoder, using optimal attention pooling, and utilizing the additional attention layers in super-resolution modules to extract information from the text.
DeepFloyd IF can handle different texts, styles, textures, spatial relations, and concepts fusion.
Yes, DeepFloyd IF can achieve image-to-image translation by resizing the original image to 64 pixels, adding some level of noise via forward diffusion, and denoising the image with a new prompt during the backward diffusion process.
DeepFloyd IF has a special affection for text and can embroider it on fabric, insert it into a stained-glass window, include it in a collage, or light it up on a neon sign. It can also perform other tasks such as image generation, style transfer, and image super-resolution.
The success rate of DeepFloyd IF varies depending on the input image and prompt. The website provides a gallery of images and their success rates as examples.
