For that matter, we may have models/tooling that are smaller that are designed for say identification model first, then handoff to a context specific model that is optimized for a specific domain... where the two calls through tooling are more optimal than a single call to a much large model. We're already kind of close to this with how the likes of claude code work with handoffs to other tools/modules.

I can see a LOT of room to explore and partition domains into more specified models still.
