 What is DALL E 2 AI ?

DALL-E 2 is the new Open source AI that can convert text to images. It allows users to create images based on text prompts. It’s the second in the series of text-to-image generation models. This generator uses an artificial intelligence called GPT-3, which is able to understand the meaning of input words (natural language inputs) and render them into images.  DALL-E 2 can create images that don’t exist on the internet, it’s more like an actual painter who can paint anything with his/her imagination.  By using this generator, users can turn their own creative ideas into vivid pictures.

How does DALL-E 2 work ?

The DALL-E 2 uses natural language processing and AI to take the information from a text prompt and convert it into a variety of images. In doing so, DALL-E 2 can control almost every attributes in an image just like any photo editing software would. For example, text description provided to DALL-E 2 is ‘A cactus wearing Hat and Sunglasses’ the following result will be shown





Deep Learning is used to teach the AI which connections it needs to make in order to generate the final product. For this learning process, DALL-E 2 uses the Deep Learning to teach the AI which connections it needs to make in order to generate the final product. For this learning process, DALL-E 2 uses the already existing technology of CLIP (Contrastive Language-Image Pre-training), which was also developed by OpenAI. CLIP manages to find matching text descriptions for an image based on text-image pairs on the internet.
the new image variation is created in a few steps:
 
1. First, you enter a text prompt into the text encoder. The text encoder is trained by the CLIP model to encode text-image pairs. 
2. Next, a so-called prior is used to establish a link between the CLIP text embedding (based on the text prompt) and a CLIP image embedding that reflects the information from the text prompt. 
3. Finally, a decoder is used to generate new image variations that visually represent the text prompt.

This allows you to create a variety of different images with different text inputs:




Comparison of DALL-E 2 and DALL-E

The advantages of DALL-E 2 are as follows:-

• The DALL-E 2 Image to text generator creates higher quality images which DALL-E was lagging to do. DALL-E 2 is also faster than DALL-E when it comes to processing images. 
• DALL-E 2 generates more realistic images. The images produced by DALL-E 2 are more multi-faceted and have more complex backgrounds and more realistic lighting conditions and reflections. This puts the final products of DALL-E 2 far ahead of DALL-E images, since DALL-E could only create cartoon-like images that often had plain backgrounds. 
• DALL-E 2 lets you add another image to the original and the artificial intelligence will combine the images and create a new variation out of them for you which we were not able to do in DALL-E.
• DALL-E 2 has a better understanding of Global Scenes. The text image generator understands what is happening in an image and retains important objects specified in the text input when creating new variations which DALL-E was not able to do.

What dangers could arise from DALL-E 2 ?

Unfortunately, it is often the case that innovative technologies such as DALL-E 2 also cause some dangers. Especially the possible misuse of the technology is one of the biggest concerns for the developers, which is why DALL-E 2 is not open source technology at this point and can only be used via an invitation from the developers.
The DALL-E 2 text to image generator has implemented some safeguards to help prevent any misuse. Input filters are designed to prevent people from creating certain types of harmful content (suggestive images of children, violent images, explicit political images, etc.). All text prompts that DALL-E 2 receives must be under strict guidelines. To ensure that DALL-E 2 cannot be abused to create violent and hateful content, dangerous weapons have been removed from the AI database.
The developers have promised that DALL-E 2 will be open publicly for all users once all threats have been eliminated.
