What Is Generative AI and How Does It Work?

Definition and Key Principles of Generative AI

Generative AI is a type of artificial intelligence that generates new content, including text, images, code, and audio, by learning from large datasets. It recognises patterns and uses machine learning techniques like neural networks and deep learning to produce realistic outputs. Generative AI can produce:

  • Text (e.g., chatbot responses, content creation)
  • Images (e.g., UI designs, graphics)
  • Code (e.g., automated coding, debugging)
  • Audio (e.g., voice assistants, music generation)

It works by using machine learning techniques, such as:

  1. Neural networks – Mimic the way human brains process information.
  2. Deep learning – Analyses massive amounts of data to generate realistic outputs.
  3. Transformers – AI models that understand context and generate accurate responses.

Generative AI can automate app development, enhance user interactions, and improve efficiency by learning from data. According to McKinsey, generative AI could automate up to 30% of work hours by 2030.

How Generative AI Differs from Traditional AI in App Development

Generative AI creates new content, such as text, images, and code, while traditional AI follows predefined rules to analyse data and make decisions. Traditional AI is commonly used for automation and predictive analytics, while generative AI powers chatbots, content generation, and AI-driven design. According to Gartner, generative design AI will automate 60% of the design effort for new websites and mobile apps by 2026.

Traditional AI and generative AI serve different purposes in app development:
