Thank you. In my mind, "planning" doesn’t necessarily imply higher-order reasoning but rather some form of search, ideally with backtracking. Of course, architecturally, we know that can’t happen during inference. Your example of the indefinite article is a great illustration of how this illusion of planning might occur. I wonder if anyone at Anthropic could compare the two cases (some sort of minimal/differential analysis) and share their insights.
