🔥 Today, we are truly excited to announce our technical prototype, the Generative World Simulation system, which integrates JING（镜）, an interactive experience model, with DAO（道）, a computable shared-world engine.

The coupled model and engine connect first-person experience with a shared world that continues to evolve beyond any individual observer.

Conditioned on actions and observation history, JING enables agent navigate, manipulate, and communicate from a first-person perspective in the world. Watch our demo video to see it in action!

On the official WBench leaderboard as of September 17, 2026, XGEN-JING ranked #1 on the Full split, and #2 on the Navi split. 🎉

DAO maintains shared world state and rules, computes the consequences of actions, and provides JING with only what the current observer can perceive. It also supports autonomous agent decision-making, enabling agents to act independently within an evolving shared world.

Together, DAO and JING move beyond generating the next frame toward simulating the world behind it. This marks a small step towards OASIS: not just a world that responds to you, but a world—and a society—that evolves with and without you. 💪

dude GPT-6 Astra is some kind of turbo-AGI machine god for 3D games. It one-shot this in 45 minutes for hardly a couple % of my quota.

I figured out how to get great graphics out of it. The trick is image gen. I'll share the process below.

meet @mostik_ai!

what happens when you put 12 PhDs in one room for four months? first place on the ARC-AGI leaderboard, which I can't say much about while the competition is still running. and this, which I can.

everyone's arguing about whether open models will catch up to frontier models. we think it's the wrong question. here's the one we pose: why does a frontier model have to generate your answer at all, when the only thing you need from it is the reasoning?

we do this by enabling models to communicate in latent space. through our protocol, hidden states pass straight from a frontier model into a small one running on your infrastructure -- no text between them, and neither model is fine-tuned. two models from different families, sharing reasoning, both left untouched.

how do we know it works? we tested it on a setup where a 753B model reads the problem, and a 4B edge-class model writes the answer. with this approach, we get results 80% as accurate as the frontier model, but at 20x faster performance.

we're committed to preventing frontier model lock-in and are already partnering with inference providers to accelerate open-weight adoption. we've done this between 15 of us, in four months, 12 PhDs and a Fields medalist, backed by @generalcatalyst

@sweatystartup ACTUALLY it is much better not to drag any attention to Tech sales or sales.
Let folks be just builders 😉

[Petr Leontev @PetrLeontev]

@devoncnp True, learning curve is insane. And nobody can tell you how it is going to be for you!

[Petr Leontev @PetrLeontev]

@Spybef0rey0ubuy How about growth continues for next 20 years?
Enough to earn enough.
Do you have a good answer for this?

[Petr Leontev @PetrLeontev]

@levelsio it is also good for building revenue streams if you are non EU.
EU tax residency is largely a joke

@stevehou DiD bros, oh.. I mean VCs

[Petr Leontev @PetrLeontev]

@iamAlexTurnbull Beautiful thing no VCs understand is that mid market and enterprise software is even better position than everyone starting from 0.
But VCs are basically VCs. DID - Dumb is dumb 👌🏻

[Petr Leontev @PetrLeontev]

Venture funded startups model might soon be dead.

Discover your unfair advantage from day 1.

That means going outside saturated markets. But VCs and founders are sooo lazy so nobody cares

[Cristóbal Valenzuela @c_valenzuelab]

It's never going to work
It's just a research demo
It's too hard
It's decades away
It works too poorly
It makes hands with six fingers
It can't do physics
Movements don't feel real
It all looks the same
It feels oversaturated
It's too hard to use
It's slop
It's too easy to use
It has no soul
It can't keep consistent characters
It can't do real audio
It's only good for memes
It can't do good voices
It can't do dialogue
It's never going to be used for real stories
It's just a few seconds
It can't hold a shot longer than a clip
It's just for experiments
It can't do good stories
It can't lip sync
It can't be directed
It's not 16-bit EXR
It's not 10- and 12-bit ProRes and HEVC
It's fine for previz, but never final pixels
It's never going to be used by real artists
No studio will ever touch it
It will never win awards
It has no emotion
It can't make you feel anything
Audiences will always be able to tell
People will never like it
It will never be able to entertain
It will ...

@HarryStebbings Hahahah, good joke man 😂

[Petr Leontev @PetrLeontev]

@LondonMoneyFS UK tax and benefits is the largest scam in the world

[Petr Leontev @PetrLeontev]

@danellisona your chances to die prematurely also decrease, so think twice

@elshayib_ you are confusing vocal minority with what really brings a good chunk revenue

[Petr Leontev @PetrLeontev]

@moseskagan luck favours a lot of sweat 💦

[Arslan @_ai_jedi]

I've tasted the 9-to-5. I've also tasted being a founder.

I highly recommend being born into generational wealth.
