Agency is really tricky I agree, and I think there is maybe a spectrum. Some folks seem to be really internally driven. Most of us are probably status quo day to day and only seek change in response to input.

As for multi-modal not being strictly word prediction, I’m afraid I’m stuck with an older understanding. I’d imagine there is some sort of reconciliation engine which takes the perspective from the different modes and gives a coherent response. Maybe intelligently slide weights while everything is in flight? I don’t know what they’ve added under the covers, but as far as I know it is just more layers of math and not anything that would really be characterized as thought, but I’m happy to be educated by someone in the field. That’s where most of my understanding comes from, it’s just a couple of years old. I have other friends who work in the field as well.
