Dall-e 3 is a generative AI system created by OpenAI that enables users to create images from language-based descriptions. It is based on a transformer-based model architecture, which is a type of neural network that processes data in sequence. Dall-e 3 is an improved version of the original Dall-e 2 system, allowing for larger and more detailed images to be generated. It can be used for image generation for various applications, including artistic creations and scientific illustrations.
