Abstract: This paper deals with the possibility of application of LLM (ChatGPT) on the coffee bean roast process. To study the possibility for application of LLM on coffee bean roast process, Firstly, this paper reviews several LLMs on how LLM gives an influence in many areas because its area is so wide such as normal editing works, speak, many advises, and code development by using huge data like coffee flavor. Secondly, this paper reviews several processes of coffee from the seeding to drinking. There are many possibilities in application of AI for coffee process. However, this paper focuses on the roasting process of coffee bean because its impact is so important on coffee flavor. Finally, this study focuses on how to control the effective roast process of coffee bean by ChatGPT. This paper also implements several questions to the ChatGPT (Prompts) to confirm the possibility application of ChatGPT on coffee roast process. The results show the very useful possibility to apply for coffee bean roast process and can have many ideas.
