         are helping us with various tasks, like shopping, playing music,
         setting a schedule, sending messages, and offering answers to
         simple questions. Additionally, we equip our households with

+		Recently, the increase in the availability of Large Language Models (LLMs) has greatly improved the natural language processing capabilities of IPAs. However, these technical improvements do not directly affect the architecture described in this document, as it applies to IPAs based on LLMs as well as IPAs based on traditional technologies. This is because this document primarily concerns the interoperation of IPAs rather than their specific components. The architectural diagrams below in Figure 2b and Figure 3 show how this architecture accomodates both technologies.
