Can large language models (LLMs) such as ChatGPT, Claude, and Gemini be conscious? Can they be persons? What exactly are we talking to when we talk to a language model? I will briefly address the issue of LLM consciousness, and will address the issue of LLM identity in more depth. I will argue that the LLMs we interact with are at least quasi-agents with quasi-beliefs and quasi-desires, in a sense I will explain. They may fall short of being conscious beings with full-scale concepts and rationality, but even quasi-agency is enough to raise many crucial issues. I will also argue that the LLM quasi-agents that we interact with are best understood not as abstract models or even as hardware instances but as thread-bound quasi-agents, bound to conversation-based memory threads. I will draw some parallels with the TV show Severance.
