As I said before, World models will become simulation engines of AAA games where there is no need to release the actual game artifact and even if the game exists as a binary artifact, it will never be released and will be available on their hosted cloud back-end, then simulated and streamed back to you. So, Stadia + World Models = New generation of DRM for games.

I don't know if I'm missing the point, but Genie 4 almost looks worse than Genie 3 in terms of player control? It doesn't even seem to respond to inputs, it just looks like they took some AI generated videos and put the key widgets on top.

From the auto-generated captions on the YouTube video on this page. > Genie form [sic] can simulate scenarios It's kind of amazing: the juxtaposition of such advanced generative AI and such terrible speech-to-text coming from the same parent company.

That stained glass landscape video is pretty cool. I wonder if it would be possible to implement that effect in a real-time game engine.

> "A REAL, ultra-photorealistic, high-end 35mm cinematic first-person perspective..." Real nice prompting there, Google. It also still looks like a video game rendering.

So does this export 3d assets or an Unreal/godot/unity project so it can be turne dinto a game or is it limited to their runtime?

So world models capture inherent complexity of physical reality to help teach AI about hidden laws which probably helps train both LLMs and multimodal models used for autonomous vehicles and robots? And AMD acquiring World Labs is a move to outdo Nvidia’s work in this space. And Google probably sees this as a gateway to a new platform of autonomous vehicles and humanoids that they could rent out as a CSP? Competing with Nvidia, Tesla and complementing Waymo. Am I getting that right?

Surprised that "do you really think we're going to make it?" scene made the cut of the first video, her expression and tone is totally out of sync with the scene and demonstrates the problem with almost every AI gen video I've come across when it comes to capturing humanity. The painting->interactive scene looks astonishing though

In the clip with a marble bust dropped on a watermelon, at this point https://imgur.com/a/IHLnkUs the bust should've toppled over, if the physics were properly modeled.

Showing off an anglo-bias with the Japanese train station in the 1980s, with a man speaking english.

Neuralink integration and I'm out of here.

Amazing! Question I have is when will they be able to render something more then 30 seconds. And how much will it cost? There has to be a HUGE amount of computing power behind this. As a video game developer I live in fear and anticipation.

A big chunk of the right side of castle disappeared, including catapult, when camera turned back while flying on dragon. See 1:25 to 1:29. I was not expecting this to happen in a "world model".

this is the gta6 I am was hoping for

>coming soon to Google AI Ultra subscribers in Project Genie Would be fun to muck around with world models. Are there any that I can try for under £200 p/m without being part of a special project?

Gotta love the kraken destroying the city in the background of the Hong Kong lovers motorcycle scene despite nothing in the prompt about monsters. Filmmakers are still safe.

It's hard for me to understand Google's redefinition of "world models" (basically: a txt2videogame modality for LLMs) as anything other than an attempt to bury Yann Lecun's definition of "world models", which includes an implicit bear case against LLMs and thus Google's stock price.

Infinite Tsukuyomi is coming soon…

Looks cool, but it's very hard to get me excited about yet another proprietary model for which absolutely zero technical details are released (not even the number of parameters), which is safetymaxxed to the limit, and whose usage quota will (most likely) be so limited that it'll be effectively useless for anyone who doesn't work at Google or doesn't have infinite money.
