A Large Language Model, or LLM, is an artificial intelligence system trained on massive amounts of text data to understand and generate human language. These models are characterized by their enormous size, with billions or even trillions of parameters, and their ability to perform a wide range of language tasks such as answering questions, writing text, and translating languages. Transformers are the revolutionary neural network architecture that powers ChatGPT and other modern language models. The key innovation is the self-attention mechanism, which allows the model to weigh the importance of different words in relation to each other. Unlike older architectures, transformers can process input sequences in parallel, making them much more efficient for training on large datasets.
