Great AI. Matched to your device.

The intelligence is in the fit

A great local AI experience takes more than getting a model to load. It takes care at every layer: the models available to you, the software that runs them, and the way your device handles the work. That is where Loci puts its engineering effort.

We consider how quickly an answer begins, how smoothly it continues, and how well the device sustains that performance. A model that looks impressive on paper can be a poor everyday companion if it leaves you waiting, runs the device hot or demands too much power. Loci's approach brings these tradeoffs together around the experience you actually get.

Your whole device matters

Memory is one part of a much bigger picture. These are the factors behind a good fit:

CPU and GPU capability

Your processor, graphics hardware and the software that can use them shape how a model performs. Two devices with the same amount of RAM can deliver very different experiences.

Memory and breathing room

The model, your conversation, the operating system and your other apps all need memory. A comfortable fit leaves room for the rest of your device to keep working smoothly.

Thermals and sustained performance

Cooling matters over a whole conversation. As a device heats up, it can reduce performance to manage temperature. A brief burst of speed tells only part of the story.

Battery and power

On a phone or laptop, every answer uses energy from the same battery that powers the rest of your day. Useful AI needs a considered balance between capability, responsiveness and power demands.

Storage and everyday use

Models need space on your device, and longer conversations add to the workload. Download size, available storage and the way you use AI all matter to a practical choice.

Built for the conversation, beyond the benchmark

A quick rewrite, a long conversation and a demanding reasoning question place different demands on a model. Larger models can offer more capability, while smaller models can be remarkably effective and more responsive. The right balance depends on both your hardware and what you want to do.

That balance also changes between devices. A desktop with dedicated graphics, a thin laptop and a phone have different strengths, cooling systems and power budgets. Loci's work across Mac, Windows, iPhone, iPad and Android accounts for those differences in how local AI runs.

Guidance, with room to explore

Loci helps you find a model suited to your device, and you can explore the models available in the app. Try a different balance of capability and speed as your needs change. The current choices and compatibility guidance are there in Loci, alongside the models themselves.
