Every major AI shift started with a new kind of world model. Language. Vision. Code. The next one is physics. @saucentoss and I published a paper today defining what a real foundation model for physics has to be and why it enables Continuous Physics Reasoning. If AI is going to help build the physical world, the bar has to be much higher. Link to full paper: vinci4ddev.wpenginepowered.c…

I’m at @brainstormtech, and everyone is talking about world models. The real test: a model has to be accurate at scale. We're seeing it firsthand. Our foundation model for physics analyzed how advanced chips deform under heat for a leading US semiconductor company. 2 billion voxels, carrying geometry, materials, and predicting physics. Inference in 290 seconds. Accuracy validated against production data. Works out of the box. No post-training. AI for physics is the next frontier. Engineering, robotics, AVs, manufacturing, energy, and the entire hardware economy will run on models that compute how physical systems actually behave. Not approximate what they look like. Not hallucinate a plausible answer. Predict measurable reality.

I’m in Aspen this week for @Fortune Brainstorm Tech with John Bruggeman. AI is at the center of the agenda, but the thread I’m most interested in is what happens when intelligence has to reason through the physical world: hardware, energy, cooling, manufacturing, and infrastructure. That is the layer @Vinci is built for. Looking forward to the conversations at #BrainstormTech. If you're here we’d love to connect.

The world model conversation is moving quickly. @drfeifei’s latest piece points to a broader convergence across robotics, spatial intelligence, and hardware design. AI is moving from models that represent the world to models that compute how the world behaves. That is why physics is the next breakthrough.

Continuous Physics Reasoning is not theoretical. This week, a single engineer at a tier-1 semiconductor company used Vinci’s physics foundation model to analyze hundreds of thermal what-if scenarios. Setup in less than a min compared to hours. Runtime compressed in hour compared to days. Already shipped. Real impact.

If you only find thermal issues after production, your workflow already failed. Using Vinci, they ran 19,000 simulations and found the issue in 5 days, likely avoiding a costly re-spin. That is not faster simulation. It is continuous physics intelligence becoming infrastructure–– physics available through out the design process.

Yesterday, we spoke with a fabless company that described a 4–6 month thermal discovery cycle collapsing into 5 days. They’re building a 3DIC part and hit a complex thermal issue that historically would not show up until physical production. By then, the cost was time: 4–6 months. With Vinci, they ran 19,000 simulations and found the issue in 5 days. That is the shift: physics moving from late-stage discovery to early-stage design intelligence.

We’ve normalized making engineering decisions without physics in the room. That should bother us. Not because engineers are careless—because the workflow made it unavoidable. Physics has been too slow, too specialized, too expensive. So teams design around scarcity: -simplify early -add margin -wait for simulation -validate late -discover risk downstream The real cost isn’t runtime. It’s timing—leading to respins and delayed programs. A foundation model for physics changes this. Physical reasoning moves into the cadence of design itself. And once physics is always available, the default flips: every design decision becomes a physics decision. That’s the shift.

We wrote this paper to create clarity: What qualifies as a real foundation model for physics? What does not? What becomes possible when physical reasoning scales? vinci4ddev.wpenginepowered.c…

Semiconductors are the proving ground. If a model can reason across nanometer-scale structures, advanced packaging, HBM, thermals, warpage, and chips-to-systems constraints without losing determinism or fidelity, that is a meaningful bar. The hardest domains should come first.

Traditional simulation was built around intermittent expert workflows. Set up the case. Mesh the geometry. Tune the solver. Wait. Interpret. Repeat. That worked when physical analysis could stay episodic. It breaks when complexity, scale, and iteration volume all increase at once.

This is the shift we call Continuous Physics Reasoning. Physical reasoning stops being something you invoke occasionally. It becomes continuously available across architecture, design, validation, manufacturing, and operations. Not a checkpoint. An always-on intelligence layer.

Why now? Because the next bottleneck is not generating text faster. It is reasoning through physical constraints fast enough to matter. Chips. Packaging. Power. Thermals. Manufacturing. Data centers. Energy systems. The systems that matter now are constrained by physics.

A real foundation model for physics cannot just produce plausible outputs. It has to be: deterministic repeatable solver-grade accurate geometry-native manufacturing-resolution general across new systems useful out of the box In engineering, “looks right” is not a category.

Same model working out-of-the-box across all types of parts, physical scales and industry be it semiconductor or robotics. End to end automation. 33M degrees of freedom problem solved in 20 seconds of inference. No fine tuning, no customization. Continuous physics intelligence.

We started where physics is hardest. First: advanced memory packaging. Thermals, density, stack complexity. Then: CPUs. Full-system power maps, matching experimental data. Then: foundry workflows. Detailed package/RDL runs in seconds. No manual meshing. Now: mechanical systems. Different domain. Same requirement: - deterministic - FEA solver-accurate - manufacturing-resolution - zero-shot (no per-case setup or tuning) This is how a foundation model for physics gets built: start with the hardest constraints, validate under real engineering conditions, then expand outward.

Honored Vinci won the ISIG Startup Competition. The real signal from ISIG: the hardest problems in AI infrastructure are now physical. Power. Cooling. Heat. Manufacturability. The last wave of AI worked on words. The next great intelligence will help build matter. That's what we are shipping at getvinci.ai

.@AnneliesGamble has been a backer of Vinci since day 0 and has one of the most rigorous takes I’ve seen on AI for physics. Getting reliable behavior in engineering environments is hard. But that is also what makes the opportunity to build enduring simulation infrastructure so compelling.

AI will generate more hardware designs. Physics will determine what ships. We’ve now extended Vinci from thermal to full thermo-mechanical simulation (stress warpage) at manufacturing resolution. Already benchmarked across real semiconductor workflows — from HBM and advanced packaging to fabless and PCB environments. Deterministic run after run. Deploys without per-customer tuning or custom code. The foundation model now extends across coupled thermo-mechanical behavior. As hardware design accelerates, validation can’t remain human-bounded. Physics has to become infrastructure. That’s the layer we’re building. More details: getvinci.ai Press release: getvinci.ai/news/vinci-ships…

Today, we announced that we are deploying a foundation model for physics for hardware design– giving a single engineer the ability to explore more materials, design variations, and configurations in a matter of a day compared to what an entire team would test in weeks. “Foundation model” means we deploy a pre-trained general model for a physics that applies across many problem classes, materials, geometries, and industries without retraining per customer or per use case. We're shipping our software in industrial/enterprise environments. Our customers’ data stays private. What this unlocks: - ~10³× faster than traditional physics solvers - Deterministic - Accurate results for the underlying partial differential equation-governed phenomena - Multi-scale - resolving single-digit nm level features on centimeter scale domains– spanning 7 orders of magnitude between the smallest feature size and the domain size. Same model. Same software. Because the laws of physics are universal. Now onto some cool viz! Here is the video showcasing the product
