Large language models (LLMs) like LaMDA, GPT-3, and ChatGPT have been the subject of widespread discussion. This workshop focuses on an analysis of interactions with LLMs. Assuming that not all interactions can be reduced to mere tool use, we ask in what sense LLMs can be part of a group and take on the role of conversational partners. Can such disparate partners as humans and smart machines form a group that takes not only linguistic actions (a conversation) but also other actions, such as producing text or making decisions? To address these questions, both the attributions of abilities to individual group participants and the ways in which the abilities of such groups can be described will be examined. This raises new questions for the field of social ontology, namely whether there are "social kinds" that are not exclusively constituted by humans. On the other hand, debates about the constitution of groups and their agency can contribute to analyzing the interactions of humans and smart machines. We expect to promote a dialogue among philosophers dealing with social groups, linguists, and artificial intelligence, respectively.
