I was impressed with their video of a drone race on Mars during a sunset. In part of the video, the sun is in view, but then the camera turns so it’s out of view. When the camera turns back, the sun is where it’s supposed to be.
there's mention of memory in the post — the model can remember where it put objects for a short while, so if it pans away and pans back it should keep that object "permanence".
