Draft review: Data Hall Twin architecture and Sky Above You card updates; other assets and demo links load from machadvisory.ai.

AI Experiments you can try in your browser.

Sixteen working browser demos, from hand control and spatial interfaces to voice, security, the sky above you, and a data hall simulation. Pinch to click, sort files in the air, or build in 3D. The ten hand demos run on your device, and a mouse works too.

Data Hall Twin // Architecture

How the hall responds.

A browser GPU simulation drives the hall. A locally trained surrogate helps preview a steady field and screen fixes.

Before your visit, NVIDIA Warp reference simulations train a Fourier neural operator with NVIDIA PhysicsNeMo. The published weights download from this site. In your browser, controls feed a WebGL2 live solver for telemetry, and a Web Worker runs the surrogate for an optional steady-field view and fast fix screening. Three.js renders the hall. A local rule engine tests candidate fixes on a coarser simulation fork, then Apply updates the live hall. Nemotron 3 Super is proposed for a future live version and is not called by this demo.
The surrogate was checked against Warp reference simulations, not a real data hall or the live solver. Its visual field can disagree with live-solver measurements.
  1. Train before the visit. NVIDIA Warp produces reference airflow cases; NVIDIA PhysicsNeMo trains a Fourier neural operator on them. The site ships its 9.51 MB weights with the demo.
  2. Simulate on your machine. WebGL2 runs the live solver and provides the HUD and rack measurements. A Web Worker runs the surrogate with WebAssembly SIMD or JavaScript; Three.js draws the hall, airflow and heat.
  3. Test fixes locally. A rule engine screens options with the surrogate and measures the best two on a coarser fork of the simulation. Apply changes the live hall and re-measures it. This mock-up makes no LLM or analytics request; NVIDIA Nemotron 3 Super is proposed for a future live version.
Sky Above You // Architecture

How the sky comes together.

Browser math and graphics draw the sky. Ask the Sky™ AI helps you explore it.

A dated CelesTrak snapshot, NASA imagery, current time and an approximate IP location, chosen city or permitted device location feed in-browser orbit calculations and a WebGL sky view. A time-zone estimate is the fallback. Ask the Sky™ AI sends a question and city to a server, then returns guidance without calculating orbital positions.
Orbital positions are computed for the selected time from a dated data snapshot; the snapshot is not a live satellite feed.
  1. Start with real inputs. A packaged CelesTrak orbital snapshot and NASA imagery give the browser its source material. Our Worker estimates your city from your IP address by default. You can choose a city or grant device location access; if the IP estimate is unavailable, the page uses your browser time zone.
  2. Calculate locally. satellite.js uses SGP4 to compute positions and passes; Three.js and WebGL render Earth and the sky as you move through time.
  3. Ask the Sky™ AI. If you use it, an email gate comes first. Your question, city and limited sky context then go to NVIDIA Nemotron 3 Super on Cloudflare Workers AI. The guide can call browser tools for sky facts, then explain or navigate; the browser remains the source for positions and times.

How it works

Your camera. Your computer. Nothing else.

01 // Camera

Frames stay in the page

The browser asks for your camera. Frames are processed on your device and are never saved, uploaded or sent. Say no and use a mouse instead.

02 // Model

A small model finds your hand

It marks 21 points on each hand, in the browser. A steady-cursor filter keeps the ring still while your hand is still.

03 // Gesture

Seven gestures, one cursor

Pinch, open palm, fist, thumbs up, thumbs down, peace sign and point. Each demo maps them to its own actions.

Straight talk

What to know.

01 // Tested

On a Mac, in Chrome

Automated checks cover every page in Chrome at laptop, tablet and phone sizes. Firefox was checked by eye and Safari was not tested. Data Hall Twin is for laptops and desktops only: it was checked in Chrome on a laptop or desktop, and phones and tablets are not supported. How well your hand is read depends on your camera and light.

02 // Sample data

Demos use made-up content

The mail, the files and the vault in the Atlas are invented. Nothing touches your real files and no account is accessed.

03 // Prototypes

Labs, not products

These are working experiments for trying an idea. Hand control inside your own apps is a separate step.

What is Mach AI Labs?

Mach AI Labs has sixteen browser demos from Mach Advisory: ten hand-control experiments, Crosscheck AI™, Model Atlas™, Voice Mirror™ for local voice cloning, Poisoned Document™, a prompt-injection demo, Sky Above You™, a real-time view of the satellites overhead, and Data Hall Twin™, a live airflow and heat simulation of an AI data hall for laptops and desktops.

Do I need to install anything?

No. Every demo opens in a web page. The hand demos ask for your camera, and a mouse works too. Crosscheck AI and Poisoned Document ask for an email address to start, and so does Ask the Sky™ AI. Voice Mirror downloads about 1.5 GB of model files on first use and works best in a WebGPU browser. Data Hall Twin needs a laptop or desktop browser with WebGL 2.

Is my camera video uploaded or saved?

No. In the ten hand demos, frames are processed on your device and are never saved, uploaded or sent. The page shows a live counter of browser requests to other sites, and it should read 0. Button identifiers in those demos, Crosscheck AI, Poisoned Document and Model Atlas are counted in Google Analytics; camera frames, question text, and form entries are not included. Crosscheck AI, Poisoned Document and Ask the Sky™ AI are different: your questions go to our server (Ask the Sky™ AI also sends your city), so please do not type anything personal. Voice Mirror, Sky Above You and Data Hall Twin run in your browser and do not send in-demo button analytics.

Which gestures do the hand demos use?

Seven: pinch, open palm, fist, thumbs up, thumbs down, peace sign and point. Each demo maps them to its own actions.

Which browser and device should I use?

Automated checks cover every page in Chrome at laptop, tablet and phone sizes. Firefox was checked by eye and Safari was not tested. Data Hall Twin is for laptops and desktops only: it was checked in Chrome on a laptop or desktop, and phones and tablets are not supported. How well your hand is read depends on your camera and light.

What is Crosscheck AI?

Crosscheck AI is a hosted demo where you ask questions about a made-up insurance claim: a kitchen photo, a repair invoice, a recorded call, a policy, a fire report and a spreadsheet. With Investigate on, NVIDIA Nemotron 3 Super searches the files, does the sums and shows every step.

What is Model Atlas?

Model Atlas is a browser demo that compares curated AI models with sample or entered hardware memory and shows illustrative fit, suitable workloads and tradeoffs. The public page cannot verify exact computer memory or benchmark performance.

What is Voice Mirror?

Record a short sample of your own voice, type a new sentence and generate speech in your browser with the open Chatterbox voice-cloning model. It needs a large first-time model download and a capable browser; CPU fallback can take many minutes. Use only a voice you own or have permission to clone.

What is Poisoned Document?

Poisoned Document is a hosted security demo. One file in a made-up company's vault hides an instruction a person would never see, and a real model, NVIDIA Nemotron 3 Super, can be tricked into leaking a fake code. Switch on three defenses one at a time and watch the same attack fail. Nothing in it is real, and it asks for an email address to start.

What is Sky Above You?

Sky Above You is a mock-up that shows the real satellites over your head right now, drawn on NASA imagery of Earth. Every position and time is computed in your browser from a public orbital-data snapshot (CelesTrak, 17 Oct 2026), so they are real but not live-updated. Our Worker uses your IP address to estimate an approximate location by default; if unavailable, the page uses your browser time zone. You can choose a city or allow device location instead. Ask the Sky™ AI, powered by NVIDIA Nemotron 3 Super, can answer questions about the sky and move around it for you. It sends your question and your city (not your coordinates) to our server and asks for an email to start. Device coordinates stay in your browser. There is no camera and no account.

What is Data Hall Twin?

Data Hall Twin™ is a laptop or desktop demo only: it was tested in Chrome on a laptop or desktop, and phones and tablets are not supported. It is a mock-up of an AI factory data hall with 74 GPU racks in 4 rows. A simplified 3D airflow and heat simulation, about 0.11 m per cell, runs on your graphics chip. Drag racks, block floor vents, raise the GPU load, close the cold-aisle doors or switch from air to liquid cooling, and the heat map and the efficiency number (PUE) update as you go. There is no account and no camera.

What is the AI model in Data Hall Twin, and how accurate is it?

The AI model is a neural surrogate: a Fourier neural operator with 4,736,648 weights, trained on a laptop with NVIDIA PhysicsNeMo on 800 airflow and heat simulations that NVIDIA Warp ran for this hall with different layouts, loads and cooling settings. On 100 held-out layouts its rack inlet temperatures are off by 0.56 C on average (guessing the average field is off by 2.07 C), and it names the hottest rack correctly in 71 of 100 (in its top 3 in 91 of 100). The worst rack in a layout is off by 3.2 C on average, 9.8 C at the 95th percentile and 23.3 C at worst. These errors are against the Warp reference, not a real hall, and the live solver on the page uses different numerics, so the two can disagree. It is not an NVIDIA checkpoint; NVIDIA, Warp, PhysicsNeMo and Nemotron are trademarks of NVIDIA Corporation, which does not endorse this demo.

What does the Data Hall Twin operator do?

The operator watches for racks that run hot, GPUs that slow down and a high PUE. When it finds a problem it tests fixes on a copy of the simulation, such as closing the cold-aisle doors, opening blocked vents, moving a rack, lowering the supply air temperature or switching to liquid cooling, then offers the best one with an Apply button and the measured before and after numbers. The copy runs on a coarser grid, so after you apply a fix a single rack can differ from the tested figure by up to 1.4 C. In this mock-up it is a rule engine plus the simulator and the surrogate, with no language model. The live version would ask NVIDIA Nemotron 3 Super to choose among the tested options and explain them.

Does Data Hall Twin send my data anywhere?

No. The simulation, the AI surrogate and the operator all run in your browser. The page downloads its own files, including 9.51 MB of model weights, from machadvisory.ai and sends nothing back: there is no account, no analytics and no AI service call. It remembers only whether you turned night vision on, in your browser.

Is Data Hall Twin engineering-grade?

No. It is a mock-up. The solver is coarse and uses illustrative constants, and the AI surrogate copies a coarse reference simulation that was not validated against measurements and gives no uncertainty estimate. The numbers are not engineering-grade, not NVIDIA specifications and not a quote. Use it to see how layout, load and cooling interact, not to size a real hall.

Can Mach build something like this for my product?

Yes. Mach engineers and launches AI-first products. Hand control inside your own apps is a separate step from these demos, so tell us what you want to try.
