As an AI language model, I undergo continuous training in order to improve and update my responses. The frequency of updates can vary depending on the developers who are responsible for my maintenance and development. Typically, major updates may occur a few times a year, while smaller, incremental updates may happen more frequently. It's also worth noting that my training data comes from various sources, so the frequency of updates can depend on how often those sources themselves are updated. In general, my training is designed to keep me up-to-date and as accurate as possible given the available information.
