Yeah, same principle. If you're passing messages between things that will react exactly the same to the same prompt, there's not a lot of point (unless the parallelism is important). If you've got fine-tunes, the whole point is that they will be better at some questions than the baseline.

Mind you, there's another idea there about mixture of experts as implemented by deciding which fine-tune to load, depending on the prompt itself... I'm sure that's been looked at.
