Folks. Can I explain something about world models? Seems like today might be a good day for that.

Advances in large-scale “world models” — whether developed by partners like Google or others — materially expand the frontier of interactive content creation. These models can generate high-quality, interactive, video-like experiences from natural language or minimal input.

Today, they are primarily editable through prompting, which limits the level of determinism and precision required for production-grade game mechanics. As a result, their outputs remain probabilistic and non-deterministic, making them unsuitable on their own for games that require consistent, repeatable player experiences.

Rather than viewing this as a risk, we see it as a powerful accelerator. Video-based generation is exactly the type of input our Agentic AI workflows are designed to leverage—translating rich visual output into initial game scenes that can then be refined with the deterministic systems Unity developers use today. Our agents already generate high-quality scenes from static video. Interactive, camera-controllable video from world models would further enhance this pipeline and materially improve the fidelity and speed of early-stage content creation. We believe this represents a meaningful step forward for AI-driven development across the industry.

Unity’s role is to operationalize these advances. Outputs from world models are ingested into Unity’s real-time engine, where they are converted into structured, deterministic, and fully controllable simulations. Within Unity, creators define physics, gameplay logic, networking, monetization, and live-operations systems to ensure consistent behavior across devices and sessions.

This combination enables developers to move faster from concept to scalable product: AI accelerates environment and asset generation, while Unity provides the execution layer that transforms generated content into reliable, monetizable experiences.

As a result, world models expand content supply and reduce development friction, while Unity remains the system of record for runtime, distribution, and long-term operations. This dynamic broadens Unity’s addressable market and reinforces its central role in the interactive ecosystem.

Congrats @TeamCherryGames on the incredible journey to Silksong! Creating a giant game with a small team takes powerful tools, and we’re proud to help bring your vision to life across platforms.

Finally deleted the X and Facebook apps from my phone. The clincher was their refusal to let me open links in the system browser.

@RouaniJihad Ah, that one I think is coming in 2025 indeed :)

We recently spent a week jamming on the #Unity API documentation. I wrote a little report about it: https://t.co/SK6O7yU70i

[Richard Fine @Superpig]

@RouaniJihad I would not call 39,000+ symbols “a lack of extensive API” :)

It might be missing specific things that you want, but that’s a separate problem!

@Cmdr_Hadfield Bonjour-hi :)

Enjoying #unity6 ? I had the pleasure of creating its key art visual — using Unity 6, of course!

First Time Ghost scenes released! ✨

We’ve just published two projects: showcasing the character and the grassy environment scene.

Have a look at the hair simulation…

[Will Goldstone @willgoldstone]

It's here. #Unity6

[Larry Hryb, Gamer Emeritus 📱⌨️🖱️🎮 @majornelson]

Today @Unity 6 releases . Our '6 Hours of Unity 6' livestream kicks off in about an hour at 8a PT/11aET/1500 UTC. I kick off the stream followed by product team interviews. Drop by, say hi and learn about the latest release.

@JustJakeSimpson @Khakionion Ohhhhhhhhhhhh

[Richard Fine @Superpig]

I don't understand the furore about the changes to Block. If my posts are set to public, then can't anyone I've blocked *already* view them, just by signing out / opening an incognito window?

[Richard Fine @Superpig]

@SoftLeafStudios @Snoopy_20111 What do you mean by "natively support?" There's some screen reader functionality built into both Unity (https://t.co/XuMZGhAei3) and Unreal (https://t.co/6a3KeUzWfW).

I’ll say this for the US Republican party: they don’t send me as much spam as the Democrats do.

Heathrow T2 surprisingly busy for 5am…

[Richard Fine @Superpig]

Man, getting from Heathrow to the nearby hotels is such a mess. Massive queue for taxis; bus that runs once an hour and will take 30mins to get to my hotel, which is about 1 mile away. I could walk it faster than that, except that you’re not allowed to walk through the tunnel…

[Richard Fine @Superpig]

@RouaniJihad @LizCouto Soon!

[Richard Fine @Superpig]

@CiroContns @aras_p I’m coming to look at Sentis and NNs as being like a new kind of programming language - implementing functions through statistical inference, instead of through algorithms. For some problems that’s insane, but for other problems it’s very effective!
