An LLM (Large Language Model) is an overpowered language model. Unlike more conventional NLP models, it is trained on very large quantities of text and is not restricted to one type of task. LLMs are sometimes colloquially referred to as "statistical parrots", because they are trained to produce a probable sequence of words. This also explains their "hallucinations" and why some of the content they produce is false. The public release of GPT-3.5 in autumn 2022 allowed the general public to discover the power of large language models. Since then, an AI race has begun between the GAFAMs with the release of Meta's LLaMA, or Google's LaMDA, which powers the Bard conversational agent.
