AI generates realistic human images mainly through Generative Adversarial Networks (GANs) and Diffusion Models. GANs have two models that “compete” — one creates images and the other checks if they look real, which pushes the quality higher. Diffusion models start from random noise and refine it step by step into a detailed image from your text prompt. Because they’re trained on huge datasets of real photos, they can reproduce fine details like skin, lighting, and natural expressions that make the results look almost real.
I’ve also experimented with this for one of my projects. For example, I used AI to generate images for a site about pregnancy tracking: calculadora de idade gestacional. It turned out to be a great way to get professional-looking visuals that matched the theme, without needing a photographer or stock images.
