How does ChatGPT handle user input that requires a long-term memory or context?

ChatGPT has a long-term memory that allows it to remember information from previous interactions with the user. This helps ChatGPT maintain context and continuity in conversations, even if there are gaps in the conversation or the user returns to the conversation after some time. Additionally, ChatGPT uses a technique called "attention" to give more weight to certain parts of the conversation history that are more relevant to the current context. This helps ChatGPT focus on the most important information in order to generate a response that is relevant and accurate.
