Natural Language Processing (NLP) and Generative AI have become critical fields within artificial intelligence. Both focus on enabling machines to interact with language in ways that feel natural and engaging. While they share many similarities, they serve distinct purposes and work differently. This article unpacks the differences, highlights the overlaps, and shows their impact on real-world applications.

What is NLP?

NLP stands for Natural Language Processing. It focuses on enabling machines to understand and process human language. This includes analysing and interpreting text or speech using machine learning and deep learning methods. NLP plays a significant role in applications like customer service, translation systems, and voice assistants.

NLP systems rely on labeled data for training. Algorithms are designed to identify patterns in syntax, semantics, and grammar. This allows them to process text-based tasks, such as sentiment analysis or keyword extraction.

For example, in text generation, NLP ensures a chatbot can respond appropriately by understanding the user’s intent. It handles tasks that require a clear understanding of natural language rules.

What is Generative AI?

Generative AI refers to systems designed to create new content, such as text, images, or even audio. Generative AI models work by learning from vast amounts of training data. They predict patterns and generate new outputs based on learned relationships.

One of the key technologies behind this is language modelling. A large language model, like GPT, uses billions of data points to generate coherent and realistic text. Similarly, image generation tools create pictures from scratch.

Generative AI works differently from traditional systems. It focuses on creating realistic outputs rather than just processing or interpreting input. For instance, it generates responses in a conversational style or creates entirely new visuals based on prompts.
