LLM

aka large language model... A language model is a probability distribution over sequences of words.[1] Given any sequence of words of length m, a language model assigns a probability... to the whole sequence. Several modelling approaches have been designed to surmount this problem, such as applying the Markov assumption or using neural architectures such as recurrent neural networks or transformers. https://en.wikipedia.org/wiki/Language_model (see GPT)
