What is the difference between text-to-image and image-to-image generation?

Asked on Oct 22, 2025

Answer

Text-to-image and image-to-image generation are two distinct processes in AI image creation, each serving different purposes. Text-to-image generation involves creating images from textual descriptions using models like DALL·E or Stable Diffusion, while image-to-image generation modifies or enhances existing images based on input parameters or additional guidance.

Example Concept: Text-to-image generation translates descriptive text into visual content, often requiring detailed prompts to guide the AI in creating the desired image. In contrast, image-to-image generation takes an existing image and applies transformations such as style transfer, inpainting, or resolution enhancement, often using models like Stable Diffusion's img2img feature.

Additional Comment:

Text-to-image models are useful for creating entirely new visual content from scratch, based on user-provided descriptions.
Image-to-image models are typically used for editing, enhancing, or transforming existing images while retaining some of the original content.
Both methods can be combined in workflows where initial images are generated from text and then refined or altered using image-to-image techniques.
