> I want to click together a model that is laser-focused on what I am doing

This is roughly what multi-agent systems are built for.

This is possible with models too, but "making one on the fly" is much easier with agent coordination rather than model weights, since they all speak the same language.

There is an IBM Mainframe vs Google Distributed system division here. Like Seymour Cray said - two oxen or 1024 chickens.

Chickens are harder to harness, so a lot of my work is in sled-dog territory for agent harnesses & command structures.
