Loci

Eco-friendly AI

Your phone is already powered. The data center is not.

Last updated:

Loci is easier on the planet twice over: a smaller model doing less work to answer you, and a query that never becomes a reason to build another data center.

There are two ways Loci is gentler on the planet, and they stack. The model on your phone uses far less power to answer you. And using it doesn't add to the case for building more data centers. One is about the energy behind a single answer. The other is about everything being built to serve answers at scale.

1. The model is smaller, so the answer costs less power

The AI behind the big cloud chatbots is enormous. Frontier models are estimated to hold on the order of a trillion internal settings, the numbers a model tunes to work out a response. The model Loci downloads to your phone holds a few billion. That is roughly a hundred to a thousand times fewer moving parts doing the math behind your answer.

Fewer parts means less computation, and less computation means less electricity. Your phone answers on the same chip that already runs your camera and your maps, drawing power measured in watts for a few seconds. A cloud answer can wake racks of specialized processors in a warehouse, plus the storage, networking, and cooling wrapped around them.

We won't print a fake "kilowatt-hours saved" number, because the honest figure depends on which cloud model, which data center, and which power grid you compare against. What we will say is simple and checkable: a model a hundred times smaller, running on hardware you already carry, is doing far less work to answer you.

2. Using it doesn't vote for the next data center

Here is the part that rarely gets said out loud. Every question sent to a cloud AI is also a demand signal. Providers watch usage climb, forecast the capacity they'll need, and raise money to build it. Your queries are part of the business case for the next facility.

That business case is now staggering. The five largest tech companies spent more than $400 billion building this infrastructure in 2025, more than the world invests in producing oil and gas, and they expect to raise that by roughly three quarters in 2026. In the United States, data centers are on track to draw more electricity than making aluminum, steel, cement, and every other heavy industrial good combined.

A question you ask Loci never enters that ledger. It runs on your phone and it's gone. It isn't counted, forecast, or used to justify the next build. You're using a model that already exists instead of adding weight to the argument for a bigger one.

And that argument is not landing well where the buildout actually happens. In a 2026 Gallup poll, about 7 in 10 Americans said they'd oppose a data center being built near them, and more said they'd rather live beside a nuclear plant. Loci lets you use AI without feeding the thing your neighbors keep showing up to town halls to stop.

What we won't claim

Loci is not zero energy. Nothing is. Charging your phone uses power, and downloading the model once uses a connection. We won't promise a specific gallon of water or kilowatt-hour saved per question, because honest math there depends on too many variables to fake.

What's true is structural: a smaller model, on a chip you already own, with no facility to cool and no query to send, is a fundamentally different footprint than the cloud default. And it's one answer that never becomes a reason to build more.
