How AI Image Generators Work
Most AI image generators follow a simple process:
- Enter a text prompt , describe your vision in detail (e.g., “a cyberpunk Tokyo skyline at night, cinematic lighting”).
- The AI interprets your request using trained diffusion or transformer models.
- Multiple images are generated , you choose the one that fits your vision.
- Refine or upscale your chosen image (add more detail, adjust style, improve resolution).
Some tools also support style transfer (applying famous artistic aesthetics), image upscaling, and background editing. Advanced platforms even provide AI image generators from image features, letting you modify existing photos or sketches.
