This appears to be a new level of "missing the plot" to me. The push to make "ai for everyone" is now just blindly intertwined with hyper specialized "for ai engineers only" releases.

Or am I so far behind that "fine tuning your own model" is something a 12 year old who is married to chatGPT does now?

No, it's something a software engineer will do to create an app. React is not enough anymore.
