These LLMs are first created with billions of words drawn from a variety of textual sources. There is no supervision required in this initial phase. They learn the language complexities such as grammar, dialects, patterns, and contextual meaning. The resulting model is highly versatile and can undertake various tasks or a language.&nbsp;<\/p>\n\n\n\n<p>Few examples include, OpenAI\u2019s ChatGPT, Google Gemini, and Meta\u2019s LlaMA are few popular examples.
