DALLE is OpenAI's groundbreaking texttoimage generative AI system that uses diffusion models and transformer architectures to create photorealistic images from natural language descriptions. Named after artist Salvador Dalí and Pixar's WALLE, the system represents a major advancement in multimodal AI, combining natural language understanding with visual synthesis. DALLE 2, released in April 2022, introduced hierarchical textconditional image generation using CLIP (Contrastive LanguageImage Pretraining) latents, enabling unprecedented semantic accuracy and artistic control. The architecture employs a twostage process: a prior network maps text embeddings to image embeddings, then a decoder diffusion model generates images from these representations.
