The recent emergence of impressive generative artificial intelligence models is capturing attention as well as raising questions. In order to explore the potential of this technology, it is essential to determine concrete use cases that can be resolved through the use of large-scale language models. I have the privilege of presenting to you our attempt to create business value by exploiting generative artificial intelligence through our corporate ChatBot through the following subjects: - Generative artificial intelligence and how to meet its challenges - The architecture of the ChatBot and the augmented recovery generation (RAG) - The use of generative artificial intelligence beyond ChatBot
