This is an excellent book which takes readers on a journey through all that is useful and interesting in what data analysis is possible with the OpenAI API and Python tools, including a nod to other frameworks such as LangChain. It includes all the modalities one could wish for; I especially liked the chapter on audio data. If you are looking for a well-written and comprehensive guide to the many possibilities that LLMs present for analysing data, then this fine book should be high on your list.
