Today we're unveiling SKY 00-1, the first Engineering World Model towards Autonomous Manufacturing.
LLMs are great at information retrieval and code, however, the physical world involves geometric and spatial understanding. Designing complex physical objects requires long-horizon planning and latent reasoning, which LLMs weren't built for.
We stacked SKY-001 against the top frontier LLMs (GPT-6 Astra, Fable 5.1 etc) and we found that our model is 100x faster and 150x cheaper in CAD and BIM while having higher precision.
As a compositional visual world model, SKY-001 lets you "dream" a design before you build it. It explores many designs in parallel, breaks each one down into its smallest components, and reassembles them in 3D, ready to open in CAD tools like Autodesk Fusion.
With applications in several industries, SKY-001 is the first step to reimagining engineering firms.

Introducing SKY-001, the first Engineering World Model.
On CAD and BIM tasks, it beats GPT-6 Astra and every frontier model we tested:
-> 51-125x faster
- > 150-210x cheaper
-> Higher IOU than all frontier models

We launched the first Engineering World Model, SKY-001, this week and it already outperforms all the frontier LLMs in CAD and BIM in speed, cost and precision.
Here’s an example of how our model compares to OpenAI’s Astra, Anthropic’s Fable 5.1 and Google’s Gemini 4.
These results did not happen by accident. Read our technical blog to find out how we built SKY-001 (🔗 below).

👉 Generate your own game now for @arcprize.
The @skyfallai team has created a AI generator that makes ARC-AGI-3 styled games end to end with no human involvement
All games in this repo have a formal spec, solver trajectories, per level budgets and multiple layout seeds. We also have a bundled browser player to go through these games.
The generator comes up with ideas (follows a design vocabulary), creates detailed specs that are then implemented and verified (by a second agent) in multiple iterations and finally packaged in the format above.
You can run this generator locally to create any number of original games to help train/evaluate your agent.
We have taken some inspiration from @tufalabs re-arc-3 to create this generator. Please feel free to try this out, share your feedback, and contribute on this to help the @arcprize community.

We took a contrarian approach in research, and we're glad we did. The results beat our own expectations.
SKY-001 outperforms all frontier LLMs such as GPT-6 Astra, Gemini 3.8 Flash, and Opus 5.5 in both CAD and BIM. It's a big step forward for world models proving how such AI systems can reinvent manufacturing firms.
Next, we're excited to bring it to more domains such as PCB Design, Aerospace Engineering, Computer Use Agents and many more.

While designing complex physical objects via CAD, frontier LLMs try to brute-force engineering through text tokens and inevitably buckle under compounding error pile-up.
SKY-001 operates as a true spatial World Model. It plans directly in the 3D space, recursively breaking complex designs down to the smallest part, then re-assembling everything while keeping every step globally consistent.
That’s how it leaves GPT-6 Astra, Gemini 4 Argon, and Claude Fable 5.1 behind on complex CAD workflows.
Here’s a side-by-side look at a Jaguar E-type sports car and a Ducati Cafe Racer:

What if Al could design an entire machine, down to its smallest components, at a fraction of the time and cost?
@skyfallai unveiled SKY-001, the first engineering world model, designed to tackle complex engineering tasks with remarkable speed and precision. A major step towards Al that doesn't just generate ideas, but helps turn them into reality🔥

AI that can actually help design and build real objects is a big deal.
@skyfallai SKY-001 can break down complex objects, figure out how the parts fit together, and turn them into designs that work in CAD.
It also claims to be much faster and cheaper than leading AI models on CAD/BIM tasks.
Exciting to see AI moving beyond chatbots and into real-world engineering and manufacturing.

Okay, this is where the world-model argument starts to make sense.
The deep learning pioneers from Maluuba are back solving one of the biggest problems in the industry. They unveiled SKY-001, the first engineering world model.
SKY-001 isn’t just generating something that looks 3D.
It simulates different designs, breaks the object down into parts and sub-assemblies, works through the hierarchy, then rebuilds it into something that can actually open in CAD.
Plus, the results compared to frontier LLMs are hard to ignore, including claims of being 150x cheaper and faster.
That feels much closer to how real engineering work happens.
With this release, they’re also building toward autonomous manufacturing and reimagining what manufacturing firms could look like.
If this approach keeps scaling beyond CAD and BIM, the interesting question won’t be “which LLM is better?”
It’ll be whether some of these long-horizon problems should be solved with a completely different kind of model.

This dude is a math genius.
You can use the smartest systems and humans in the world and still have issues with output. You need to understand what makes a design buildable.

Great way to explore new product concepts or compare alternatives with 3D designs!
This is an engineering world model.
You give it a text prompt or an image, and it generates a 3D assembly.
Look at the examples: it breaks a design into smaller parts, creates each part in 3D, and assembles them.

Had the pleasure of embarking on the wild journey of Maluuba with @spisallyouneed building agents over 15 years ago before people were even talking about Siri or ML. Pumped about Sky 001, the team is cooking!

Our goal is not just to build better CAD and BIM designs but for SKY-001 to become the foundation model engineering firms run their core workflows on, from product design to production.
Autonomous manufacturing needs AI systems that can reason in abstract latent space. That’s why we’re doubling down on world models and moving beyond language.

The first Engineering World Model to reimagine manufacturing firms is finally here and it already outperforms frontier LLM Models at 1/150th the cost.
🧵 Meet SKY-001. For both CAD + BIM designs it is:
‣ 51-125x faster
‣ 150-210x cheaper
‣ produces higher accuracy than all frontier models
The breakthrough here shows how efficient World Models are for complex and long-horizon tasks and it shows the industry that it’s high time to pursue a different approach than large language models to achieve optimal efficiency.

The answer to every AI problem can’t be “buy more GPUs.”
Skyfall reports 51–125x faster performance and 150–210x lower cost on its engineering benchmarks with a different architecture.
Proud to be investors in @spisallyouneed and the @skyfallai team since the beginning!
