I don't know how much this API churn is going to help developers who are trying to integrate OAI into real, actual, non-wrapper products. Every vendor-managed state machine that handles conversation, messages, prompt hand-off, etc., has ultimately proven inadequate, presumptive or distracting for my use cases.

At the end of the day, all I ever seem to use is the chat completion API with structured outputs turned on. Despite my "basic" usage, I am employing tool use, recursive conversations, RAG, etc. I don't see the value in outsourcing state management of my "agent" to a 3rd party. I have way more autonomy if I keep things like this local.

The entire premise of these products is that you are feeding a string literal into some black box and it gives you a new string. Hopefully, as JSON or whatever you requested. If you focus just on the idea of composing the appropriate string each time, everything else melts away. This is the only grain that really matters. Think about other ways in which we compose highly-structured strings based upon business state stored in a database. It's literally the exact same thing you do when you SSR a webpage with PHP. The only real difference is how it is served.
