What is generative AI?

Definition

Generative AI describes a category of machine learning systems trained to produce new content that resembles their training data, rather than only labeling, sorting, or analyzing existing content.

How image generation works

Most modern image generators are diffusion models, which learn to reconstruct images from progressively noisier versions during training and then reverse that process to generate new images from random noise. Earlier and still-used approaches include GANs (Generative Adversarial Networks), which pit a generator against a discriminator model during training.

• Text-to-image and image-to-image workflows

Why this matters for detection

Each generation approach tends to leave characteristic statistical and visual traces. Detection systems, including PhotoProof AI's visual pattern analysis layer, are trained to recognize these traces across multiple generator families rather than a single model.

Is generative AI the same as a deepfake?

No. Generative AI is the broader technology category. A deepfake is a specific, identity-focused misuse of generative or synthesis techniques.

Can generative AI outputs be detected reliably?

Detection is probabilistic, not certain, and accuracy varies by generator, image quality, and post-processing. It should be one input into a broader verification process.
