# What are large language models doing **Opening (not a real abstract):** imagine that if you graduate from medical school, then you secretly hope that one day your skills will be called upon in some dramatic way. On a plane or at the theatre, the call will go out for a doctor, and you will shout, “I am a doctor!”. And you will step in and save the day. I doubt if many philosophers harbour such fantasies, but this might be the moment when society makes a similar dramatic call upon their services. For recent developments in artificial intelligence raise questions that are distinctively philosophical in nature. I am thinking, of course, of large language models (LLMs), such as OpenAI’s GPT-3 and GPT-4. These are massive neural networks that have been trained to perform text-completion tasks on vast quantities of human-produced text.
