How AI Image generators work

Most modern tools use diffusion models: neural networks trained to reverse a process of adding noise to images. Starting from random noise, they iteratively refine output to match your prompt.

Common generation modes include:

• Text-to-Image: Generate visuals from prompts.
• Image-to-Image: Transform existing images with text guidance.
• Inpainting: Edit specific regions of an image.
• Outpainting: Extend scenes beyond original borders.
• Style Transfer: Apply artistic styles consistently.

Prompt understanding is powered by models like CLIP, which aligns visual output with semantic intent, making results more accurate and context-aware.
