OpenAI’s new — and first! — video-generating model, Sora, can pull off some genuinely impressive cinematographic feats. But the model’s even more capable than OpenAI initially made it out to be, at least judging by a technical paper published this evening.
The paper, titled “Video generation models as world simulators,” co-authored by a host of OpenAI researchers, peels back the curtains on key aspects of Sora’s architecture — for instance revealing that Sora can generate videos of an arbitrary resolution and aspect ratio (up to 1080p). Per the paper, Sora’s able to perform a range of image and video editing tasks, from creating looping videos to extending videos forwards or backwards in time to changing the background in an existing video.
But most intriguing to this writer is Sora’s ability to “simulate digital worlds,” as the OpenAI co-authors put it. In an experiment, OpenAI set Sora loose on Minecraft and had it render the world — and its dynamics, including physics — while simultaneously controlling the player.

So how’s Sora able to do this? Well, as observed by senior Nvidia researcher Jim Fan (via Quartz), Sora’s more of a “data-driven physics engine” than a creative too. It’s not just generating a single photo or video, but determining the physics of each object in an environment — and rendering a photo or video (or interactive 3D world, as the case may be) based on these calculations.
“These capabilities suggest that continued scaling of video models is a promising path towards the development of highly-capable simulators of the physical and digital world, and the objects, animals and people that live within them,” the co-authors write.
Now, Sora’s usual limitations apply in the video game domain. The model can’t accurately approximate the physics of basic interactions like glass shattering. And even with interactions it can model, Sora’s often inconsistent — for example rendering a person eating a burger but failing to render bite marks.
Still, if I’m reading the paper correctly, it seems Sora could pave the way for more realistic — perhaps even photorealistic — procedurally generated games. That’s in equal parts exciting and terrifying (consider the deepfake implications, for one) — which is probably why OpenAI’s choosing to gate Sora behind a very limited access program for now.
Here’s hoping we learn more sooner rather than later.

Denis Villeneuve’smovie adaptations of Frank Herbert’s seminal sci-fi novel, Dune, has become a cultural and commercial hit. That’s big for Team Hollywood, but I still have a hard time believing that Dune has done more for movies than it has for video games — so long as you ignore the kerfuffle over whether it influenced Star Wars.
Arrowhead Game Studios has said that it knew that Helldivers 2's game master would be «divisive» with players.
Whenever Madonna sings the 1980s hit “La Isla Bonita” on her concert tour, moving images of swirling, sunset-tinted clouds play on the giant arena screens behind her.
Finn Wolfhard is often thought of as a good pick to play Link in the upcoming live-action The Legend of Zelda movie, but the Stranger Things star has another idea for a video game movie that probably wouldn’t have occurred to the majority of fans.
The developer of Stardew Valley has a hack for composers who want to get people to listen to their music; all you have to do is make an entire game from scratch.
From the dawn of Pong to the present day, thousands of video game titles have captured our hearts and our imaginations – and occupied countless hours of our leisure time – but which is truly the best ever?
The distressing news of video games layoffs continues, with over 8,000 reported job losses this year so far.
A company called Game Scent has revealed its new AI-powered device that lets players smell their games in real time. With the growing popularity of VR, as well as the introduction of haptic feedback in the PlayStation 5’s DualSense controller, companies have been increasingly interested in stimulating all five of senses while people play video games. Horizon Forbidden West used DualSense haptics to try to emulate even the feeling of walking through grass, and the ambitions to create a fully immersive gameplay experience have only grown.
The creator of viral horror video game The Mortuary Assistant is making a new, officially licensed Paranormal Activity video game.
Games are weird again!
Good news Uncharted fans, the sequel finally has a script. Mark Wahlberg, who brings treasure hunter Nathan Drake's frequently facial-haired friend Sully to life in the 2022 video game adaptation, has revealed he recently got a call from Sony telling him to "start growing [his] mustache".
