"[GraphQL] meets a lot of our goals around authorization, and our desire to, as our CTO David Strauss would say, solve the 'confused deputy problem' once and for all," she said. This simplifies the process of moving data through APIs and significantly cuts down on the work required every time something new or changes crop up in the specifications. The problem is the same, the solution just looks a bit different. using Relay to get persisted Queries. If that's the case, the deprecation model of GraphQL doesn't help you at all.

As for your specific case, I would recommend to clarify your goal on using AI in your application. GraphQL is implemented with Graphene, you can check Graphene's docs for more details.. Waterfall network requests on nested data When it comes to user experience and ease of development, the BFF is the clear winner. In these cases you’ll likely want to use a full GraphQL client that handles the lifecycle of all your GraphQL operations.
