Pictures of the model, including a video with comments from President Eyring, are available at the Mormon Newsroom article linked above, as well as the Deseret News.
It's great to be able to see some pictures of the interior. There are seven levels, and each one has different rooms: the first floor (basement) has the baptistry, the main floor has the offices, the third floor has the locker rooms, the fourth floor has the endowment rooms, the fifth floor has mechanical ducts and vents, the sixth floor has sealing rooms, and the final floor has the priesthood assembly hall. By looking at the pictures, I could see how big the assembly room is (very big!). I also learned that the mural that was recently installed at the front of the Provo Temple's chapel was also installed on the third floor of the Washington D.C. Temple (which you can see in the fifth photo on the Mormon Newsroom article).
Perhaps the Church will make some more cutaway models for other landmark temples. I think it's a great idea!
