Large Language Models (LLMs) are transforming how organisations use data, automation and artificial intelligence. But what exactly is an LLM, and how does it work in practice?
In this video, BCN breaks down what an LLM is, how Large Language Models are trained using vast datasets, and why tools like ChatGPT, Microsoft Copilot and other AI assistants rely on LLM technology.
