I don't think it currently learns new things. All of its learning and understanding is based on a fixed data set up to 2021. They (OpenAI who made it) will be bringing out new versions (such as ver 4 coming out soon and being integrated in BING search engine), which will be trained on more recent and other data sets. BUT any AI like ChatGPT can only work with the info it has been trained on, it has no in built ability to acquire new information. Yes, it can make new connections with that data, based on your prompts, and respond like a human would. BUT It only knows what it knows.
