DALL·E 2
A text-to-image model developed by OpenAI based on diffusion model architecture. It generates high-quality images from natural-language descriptions and is a representative application of diffusion models in the image generation domain.
Core Facts
Timeline (last 90 days)
The idea of diffusion models was first proposed in 2015, but it only took off after models such as DALL·E 2 demonstrated their results.
Papers similar to diffusion models appeared as early as 2015, but it was not until DALL·E 2 demonstrated stunning results in 2022 that they attracted large-scale attention.
Text-to-image technology entered the public spotlight in 2022 with the explosion of Stable Diffusion, DALL·E 2, and Midjourney.
Early Stable Diffusion and DALL·E 2 performed poorly in concept binding, while models such as SDXL, DALL·E 3, and Midjourney v5 significantly improved accuracy by introducing stronger text encoders and other strategies
The mathematical essence of diffusion models is based on stochastic differential equations and score matching theory, underpinning image generation systems such as Stable Diffusion and DALL-E.
