The use of chat bots is becoming increasingly popular as they can be programmed to assist with a wide range of tasks, from answering simple questions to providing in-depth explanations and discussions on a wide range of topics. One example of a chat bot is the one used by Graham Allen, which is likely based on a language model such as GPT-3. These language models are able to generate human-like text based on the input they receive, allowing them to engage in natural-sounding conversations and provide relevant and coherent responses.
