DALL-E 2: AI generates and edits images based on text description only

DALL-E 2: AI generates and edits images based on text description only

[17:22 sun,10.April 2022   by ]    

A little over a year ago, OpenAI had (launched) the first version of DALL-E www.slashcam.de/news/single/KI-erfindet-Bilder-nach-Textbeschreibung---DALL-E-16275.html, a neural network that can generate images using only simple text descriptions. Now the latest version has been introduced, which has numerous improvements.

DALL-E 1 and 2 in comparison

For example, DALL-E 2 not only generates better and also faster images, but also with a four times higher resolution (1,024 x 1,024) than before. And for the first time, images can not only be generated, but also edited specifically by text - individual image elements can now be both added and removed.

Some examples

DALL-E 2 (a portemanteau of Salvador DALI and WALL-E) was trained using images including image descriptions. In addition, the neural network learned the relationship between images and the text describing them. For those interested in the technical details, here is the research paper.

How does DALL-E 2 work? Examples

The input is a description of what should be in the image to be generated - not only objects that should appear in the image can be named, but also relations to other objects or even actions, so for example "a hedgehog operating a calculator" or "rabbit detective sitting on a park bench reading a newspaper in a Victorian setting".

The style of the picture can also be defined, because DALL-E 2 can reproduce photorealistic pictures as well as cartoons or abstract painting styles (like psychedelic, wax crayon or oil painting) or styles of famous painters (like Dali, Monet, Picasso and others).

Illustrator jobs at risk?

The results are amazing - after all, there are no limits to the imagination. Potentially any image can be created that one can think up and describe, no matter how fantastic or absurd the motif. It is already feared - should the algorithm be generally accessible and the image quality still somewhat better - that illustrators could lose their jobs, since also completely special picture motives can be produced completely simply after free description with DALL-E 2 in seconds - together with an immense number of picture alternatives to the selection.

Change images via DALL-E 2

The new possibility of the subsequent editing ("Inpainting") of pictures by DALL-E 2 works quite simply - thus first roughly an image area is marked, at which the change is to be accomplished and then by text described which is to be changed. For example, a hat can be put on a person, an object can be added or removed, or the background can be changed.


The special thing about this is that shadows, reflections and textures of the objects and the background are automatically taken into account during these operations, and the style (whether photorealistic or alienated) of the object is adapted to that of the image.

DALL-E 2 can also generate variations of an image.



The OpenAI team has restricted direct access to DALL-E 2&s API, i.e. the ability for (potentially) anyone to freely generate images with it, and has only released it to a small group of selected users. The possibilities of misuse are considered too dangerous - be it pornographic or violent images.

For this reason, the researchers have made an effort to filter out sexual and violent content from the training data for DALL-E 2. In addition, filters for text input and uploaded images are intended to ward off abuse of the system. Similarly, the training process has been modified to limit the ability of the DALL-E 2 model to remember faces from the training data to prevent the model from faithfully reproducing images of celebrities and other public figures.


However, if you take a closer look at the generated images, you will sometimes notice a number of image errors that are not so easy to spot from a distance: some parts of an object are often somewhat strangely distorted and indistinct.

Similarly, DALL-E 2 cannot represent objects it does not know i.e. with which it has not been trained.


The team at OpenAI hopes. that DALL E 2 will also help understand how advanced AI systems see and understand our world. This is important because DeepLearning systems are a kind of black box, since they are self-learning and it is often impossible to understand what exactly has been learned. Using DALL-E 2 the images it generates - and also the failed ones - there is the possibility to gain some deeper insights into the inner workings of the neural network.

The new version of DALL E confirms us in our already for the first generation made assumption that the next logical step, the generation and also the changing of moving images according to description, will not take much longer - at least this was already the case with many other AI algorithms for image manipulation, because videos as sequences of single images are just another, more computationally intensive dimension.
