Stable Diffusion and DALL-E 3 are both advanced AI image generators but differ in their approaches. Stable Diffusion uses positive and negative prompts to control what elements appear or are avoided in the image, enabling precise control over the output. DALL-E 3, developed by OpenAI, is known for its high level of creativity and realism, leveraging GPT-4’s advanced language understanding to produce varied and vivid images based on detailed prompts.
