So, that is a GPT interface. You can create text. Basically, let's say your job is a newsletter editor. You could automate it to pull down your file, submit your file to GPT, and spit out the response. But I don't see an announcement for PAD co-pilot just yet. I'm just going to cheat and use GPT for Power Automate because it can explain better and faster than I can:
Yes, Power Automate is available for Microsoft 365 users, but it comes with certain limitations. Users with the free plan or a Microsoft 365 license can only access standard connectors. Most of the other license plans provide access to premium connectors. If the flow doesn't use a premium connector, such as calling Dataverse in the full production environment (not the Microsoft Teams environment), having a Microsoft 365 license is enough. Microsoft 365 customers can also create solution-aware flows if the environment in which they create the solution-aware flow has a Dataverse database attached to it.
However, if users want to use premium features such as the ability to automate legacy apps on a desktop via robotic process automation (RPA) or get more AI Builder credits, they will need to purchase a separate Power Automate subscription plan. The pricing for these plans start from $15 per user per month for a per-user plan, $100 per flow per month for a per-flow plan, and $0.60 per flow run for a pay-as-you-go plan.
In essence, Power Automate without the license for connectors is pretty useless, IMO. The connectors is what give you the ability to get things going, and for $15/mo, it's not bad.
