One of the biggest differences is the conditioning signal. Genie 3 and similar input raw keyboard commands (WASD + arrow keys), while Atlas inputs camera poses. This small difference means that Genie 3 has no 3D whatsoever; the model needs to learn an internal mapping between keyboard commands, world states, and pixels; and with Genie 3 there is no clear way to control the generated world aside from the input image and text prompt. Since Atlas makes camera pose explicit it can use posed input frames to shape the generated world, giving you a lot more creative control.

Another big differentiator is multimodality. Genie 3 only outputs pixels. Atlas also outputs pixels, but it can also output explicit 3D for the cases where you need it (such as plugging into game engines, simulators, or VFX workflows)

Thanks, those are great points, now I'm definitely excited for the full release to try it out
