Why is this labeled a Beta? What can I expect during the Beta phase?

It is important to provide faculty, staff and students with swift access to this powerful emergent technology in a secure sandbox environment that protects sensitive data from leakage and where you can use your own data and work output without it becoming part of OpenAI’s model training. We have released our WashU ChatGPT instance while still in Beta in order to make a secure tool available to the university community as soon as possible. As a Beta, it may break or behave sub-optimally – a few hiccups are expected and we ask for your feedback and your patience as we continue to optimize the tool.
