In this book, I have attempted to provide an explanation that guides the reader from merely using large language models via API to defining large solutions where these models play a significant role. To achieve this, various techniques are explained, including prompt engineering, model training and evaluation, and the use of tools such as vector databases. The importance of these large language models is not only discussed, but great emphasis is also placed on the handling of embeddings, which is essentially the language understood by large language models.
