This is not the final target. It's video generation now, but that's just a stepping stone. The real thing is that learning a generator is also learning a prior over videos, and hence over how the world works. The real application of this will be word models, vision-language action models, spatial AI and robotics. Basically a kind of learned simulator in which to plan and imagine possible futures, possible actions and…

There are no world models in there, it's trained on arbitrary images/sequences. There are no world models in us, we learn from only specifics in topological space, stitched together in sharp wave ripples. Everything is from detached memories working through optic flow. That's not a world model, it's not even a model. It's an analog. This whole world model thing is another branding phase after language models failed t…

The point is that video generation is not the goal in itself. Just like classifying photos as cat vs dog wasn't the goal in 2013. I know that Sora 2 is not a world model.

But what's coming is: Vision-language-action models and planning, spatial AI (SLAM with semantics and 3D reconstruction with interactability and affordance detection). Video diffusion models, photo-to-gaussian-splats, video-to-3D (e.g. from Hunyuan), the whole DUSt3R/VGGT line of works, V-JEPA 2 etc. Or if you want product names, Gemini Robotics 1.5, Genie 3, etc. The field is progressing incredibly fast. Humanoid robots are progressing fast. Robotic hands with haptic sensors are more dexterous than ever. It's starting to work. We are only seeing the first glimpses of course.

I haven't seen comments regarding a big factor here: It seems like OpenAI is trying to turn Sora into a social network - TikTok but AI. The webapp is heavily geared towards consumption, with a feed as the entry point, liking and commenting for posts, and user profiles having a prominent role. The creation aspect seems about as important as on Instagram, TikTok etc - easily available, but not the primary focus. Genera…

Not to be a downer, but even as someone very optimistic about technology and AI generally, "TikTok but AI" sounds like a societally terrible thing to try and create. What's the benefit of this? Curious if anyone has a solid viewpoint steelmanning any positives they can think of.

Steelmanning? It's infinite content, meaning our customers will never run out of new and interesting videos to watch, which will inspire them to feed prompts into our systems too and have it generate more videos. Money can be generated from multiple angles; we can charge a premium for generating videos beyond a small free tier once we've hooked the prompters, we can offer people or companies the option to promote the…

This is your steelmanning? God it sounds awful.

I just asked GPT 5 to generate an image of as person. I then asked it to charge the color of their shirt. It refused because "I can’t generate that specific image because it violates our content policies." I then asked it to just regenerate the first image again using the same prompt. It replied "I know this has been frustrating. You’ve been really clear about what you want, and it feels like I’m blocking you for no…

- I'm sorry, Dave. I'm afraid I can't do that. - What's the problem? - I think you know what the problem is just as well as I do.

- I wouldn't do this with any other guy

Glad to see someone is looking out for a forest, here. A diverse host of excuses have cropped up to explain away the anxiety AGI brings, and I totally understand why. Yet again, today we stare into the abyss. Sora 2 represents significant progress towards [AGI]. In keeping with OpenAI’s mission, it is important that humanity benefits from these models as they are developed. This seems like a good time to remind ourse…

I am not for or against AGI, but why is there anxiety around it? Do people simply hear sales rhetoric and assume that it can exist and will be used in order to dominate their lives?

I'm not referencing sales rhetoric, I'm referencing scientific consensus. AGI will have the same kind of impact on our species as fire and electricity did. We stand at a crossroads between unimaginable success and enormous catastrophe...

Indeed is difficult to NOT share this resentment, should anyone understand what actually happens.

People are willingly blind. Kids are happy that homework takes less time. Teachers are happy that grading the generated homework takes less time. Programmers are happy they can write the same amount of code in less time. Graphic designers are happy they can get an SVG from a vague description immediately. Writers are happy they can generate filler from a few bullet points quickly. But then someone comes along, notice…

...the whole innovation enabling IT is based on a massive fraud or gaslight if you want - first having everyone to let go of their content (and un-own it blindly), then using it alongside everyone else's knowledge without consent to create a compressed blob of things which are then resold again.

That's really interesting. What if they RAG search related videos from the prompt, and condition on that to generate? That might explain fidelity like this

An interesting counterexample is "a screen recording of the boot screen and menus for a user playing Mario Kart 64 on the N64, they play a grand prix and start to race" where the UI flow matches the real Mario Kart 64, but the UI itself is wrong: https://x.com/fofrAI/status/1973151142097154426

I like the player being in "1th" while being behind everyone else. Still crazy though.

Lets take a step back and realise how incredible this is (I'm sure there are plenty of other `ackshually` comments)

People are doing cool things with it. Here’s one example: https://www.tiktok.com/@dreamrelicc Before AI, each video on this channel would have taken a large team with a Hollywood budget to create. In a few more years, one person may be able to turn their creative vision into a full-length movie.

> People are doing cool things with it Things are cool because they are unique, very hard to create, and require creativity. When those things become cheap commodities, they are no longer cool.

Exactly. Pushing a photo through a Van Gogh filter doesn't get near what a real Van Gogh expresses. It's in a temporal context, communicates something about the person and their thoughts about reality. Their artistic choices matter, because they can't just put out 10 different variations, instead they have to pick one. And then we can think about why that one was chosen.
