Is this one of those ones where they'll drop the huggingface release a week later? Or do we know for sure that this is staying proprietary?

someone correct if i'm wrong, but I think the max models are usually non-open

The plus and max models have never been open as far as I know.

		With the 3.5 release, the Plus model was just a rebrand of the open weight 397B. But I suspect that will change going forward. They haven’t released the weights for 3.6 but they did make it available through a few US providers.
