Text To Image: Definition and Examples

Text To Image is a branch of generative AI that allows creating original images from written instructions in natural language. The user writes a prompt describing the scene, style, colors or desired atmosphere, and the model produces a corresponding image in seconds. This technology mainly relies on diffusion architectures (like Stable Diffusion) or transformer models.

Text To Image models are trained on billions of image-text pairs from the internet. They thus learn the correspondences between linguistic concepts and their visual representations. During generation, the model starts from random noise and gradually refines it, guided by the prompt, until a coherent and detailed image is obtained.

Applications are vast: artistic creation, graphic design, rapid prototyping, editorial illustration, generation of marketing visuals or concept art for video games and cinema. Tools like DALL-E, Midjourney, Stable Diffusion or Flux have made this technology accessible to the general public.

The quality of the result strongly depends on the precision and structure of the prompt. This is why prompt engineering applied to Text To Image has become a skill in its own right, combining artistic vocabulary, technical understanding of models and mastery of generation parameters.
