Hey @broad-angle-94955 will jump in here as the team is back later on in the day. In short, you don't need to upgrade to the 'Teams' plan to start using GPT-4. The 'Teams' plan is basically designed for agencies who receive high volumes of interactions with their chatbot, so they can save money ($500) by upgrading. I asked them yesterday, currently, you can only use GPT-4 with the KB answering. Of course, your AI token usage will be higher if you select this option! They are working on introducing GPT-4 to AI Task and AI Generate as well.
