A Large Language Model (LLM) is a type of machine learning model that is trained on a vast amount of text data. Essentially, these models learn patterns in human language and generate text that mimics human-like writing. They are designed to improve performance in Natural Language Processing (NLP) tasks such as language translation, question answering, summarization, and more.
How Large Language Models work
Large Language Models learn from the statistical patterns in the data they are trained on. Typically, they are trained on entire internet text or sizable subsets of it. These models utilize algorithms such as the Transformer architecture, which allows them to understand the context in text data.
The models are trained to predict the probability of a word given its preceding words in a sentence, a process called autoregression. This way, they learn grammar, facts about the world, reasoning abilities, and also unfortunately, any biases in the data they were trained on.
For instance, models like OpenAI's GPT-3 consist of 175 billion machine learning parameters, enabling them to generate impressively human-like text. When given a prompt, these models can generate coherent and contextually relevant sentences. Furthermore, they can be fine-tuned for specific tasks, increasing their versatility and utility in various domains.
