Large Language Models (LLMs) are artificial intelligence models developed to understand and generate human-like text. They’re often an important component in chatbots, search engines, and language translation apps, among other AI systems. In a tech interview setting, LLMs-related questions test a candidate’s knowledge in natural language processing (NLP) and deep learning algorithms. The discussion would likely revolve around how these models are trained, their uses in diverse applications, and the common challenges linked with large language models - in particular, their handling of context, bias, and ethical considerations.
