A large language model (LLM) is an AI system trained on vast text datasets to understand and generate human-like language. These models recognise patterns across billions of words, enabling them to respond to prompts, summarise information, draft content, and support a wide range of language-based tasks. Their ability to understand context makes them significantly more capable than earlier rule-based or keyword-driven systems.
In marketing, LLMs support everything from research and content development to data extraction and workflow automation. They help teams analyse large volumes of information, identify trends, generate campaign ideas, and streamline production of assets such as emails, landing pages, and nurture sequences. Beyond creation, LLMs also enhance personalisation by tailoring messaging to specific audiences, buying stages, or intent signals with far greater speed and consistency than manual methods.
When used ethically and strategically, they augment creativity and efficiency, freeing marketers to focus on insight and strategy rather than repetition.
