Genie delivers on-the-fly generated video that responds to user inputs in real time. Marble renders a static Gaussian Splat asset (like a 3D game engine asset) that you then render in a game engine. Marble seems useful for lots of use cases - 3D design, online games, etc. You pay the GPU cost to render once, then you can reuse it. Genie seems revolutionary but expensive af to render and deliver to end users. You never stop paying boatloads of H100 costs (probably several H100s or TPU equivalents per user session) per second. You could make a VRChat type game with Marble. You could make a VRChat game with Genie, but only the billionaires could afford to play it. To be clear, Genie does some remarkably cool things. You can prompt it, "T-Rex tap dancing by" and it'll appear animated in the world. I don't think any other system can do this. But the cost is enormous and it's why we don't have a playable demo. When the cost of GPU compute comes down, I'm sure we'll all be steaming a Google Stadia like experience of "games" rendered on the fly. Multiplayer, with Hollywood grade visuals. Like playing real time Lord of the Rings or something wild. Interestingly, there is a model like Google Genie that is open source and available to run on your local Nvidia desktop GPU. It's called DiamondWM [1], and it's a world model trained on FPS gameplay footage. It generates a 10 fps 160x160 image you can play through. Maybe we'll develop better models and faster techniques and the dream of local world models can one day be realized. | ||
