Generative AI

Generative AI refers to AI systems that create new content, such as text, images, audio, or code, rather than just analyzing or classifying existing data.

Key takeaways

  • Generative AI creates new content, like text, images, audio, or code, rather than just analyzing existing data.
  • Large language models and diffusion models are both examples of generative AI.
  • Generative models learn statistical patterns from training data and use them to produce new, similar output.
  • Generative AI differs from traditional discriminative AI, which classifies or predicts rather than creates.
  • Many products combine generative models for content creation with traditional models for filtering and ranking.

What is generative AI?

Generative AI is a broad category of AI systems designed to produce new content — writing an essay, drawing an image, composing music, or writing code — rather than performing a narrower task like classifying an email as spam or predicting a number. Large language models, diffusion models, and other generative architectures all fall under this umbrella.

How generative AI works

Generative models are trained on huge amounts of existing content and learn the underlying statistical patterns of that content, whether that's how sentences are structured, how pixels form recognizable images, or how musical notes typically follow one another. At generation time, the model uses those learned patterns to produce new output that resembles, but doesn't copy, what it was trained on.

What generative AI is used for

Generative AI powers chatbots and writing assistants, AI image and video generators, code-completion tools, and voice synthesis. It has moved from a research curiosity to a mainstream part of software products across nearly every industry since the early 2020s.

Generative AI vs traditional AI

Traditional, or discriminative, AI systems are typically built to make a decision or prediction about existing input, such as detecting fraud in a transaction or recognizing a face in a photo. Generative AI instead creates new output. Many modern products actually combine both: a generative model to produce content, and traditional classification models to filter, rank, or moderate that output.

Frequently asked

What is generative AI in simple terms?
Generative AI is AI that creates new content, such as text, images, or audio, based on patterns it learned from training data, rather than just analyzing existing content.
Is ChatGPT generative AI?
Yes. ChatGPT is a generative AI application built on a large language model that generates new text in response to prompts.
What is the difference between generative AI and machine learning?
Machine learning is the broader field of systems that learn from data; generative AI is a subset of machine learning focused specifically on creating new content rather than making predictions or classifications.
