DALL-E is an artificial intelligence program developed by OpenAI that generates images from textual descriptions. It uses a neural network to understand the details in the text and create corresponding visuals, allowing users to see their ideas come to life in unique and creative ways. The name DALL-E is a combination of the famous artist Salvador Dalí and the animated robot WALL-E from Pixar. This reflects the program's ability to produce imaginative and artistic images while also being rooted in technology. Users can input various prompts, and DALL-E will generate a wide range of images based on those descriptions.
