It isn't even vaguely a distill of o1. The reasoning models are, from what we can tell, relatively small. This model is massive and they probably scaled the parameter count to improve factual knowledge retention.

They also mentioned developing some new techniques for training small models and then incorporating those into the larger model (probably to help scale across datacenters), so I wonder if they are doing a bit of what people think MoE is, but isn't. Pre-train a smaller model, focus it on specific domains, then use that to provide synthetic data for training the larger model on that domain.
