Generative AI
Generative AI creates new text, images, audio, video or code based on learned patterns and user instructions.
Short definition
Generative AI is a category of AI systems that produce new content. Instead of only classifying or ranking existing data, these systems can write text, generate images, compose audio, create video, draft code or synthesize structured outputs.
How it works
Generative models learn patterns from training data and then produce outputs that fit a prompt or context. A large language model generates text by predicting tokens, while image models generate visual data from text prompts, reference images or both.
Example
A marketing team can use generative AI to create headline options, summarize customer interviews and draft campaign variants. A product team can use it to generate code snippets, support replies or documentation drafts.
Why it matters
Generative AI reduces the cost of first drafts and rapid experimentation. The tradeoff is quality control: generated content can be wrong, generic, biased or legally sensitive. Strong workflows combine generation with review, source grounding and clear usage policies.
