A World First for GB1: Local AI Models, Right on Your Device

We're thrilled to announce something we've been working towards for a long time: GB1 now runs AI models directly on your phone or tablet — no internet connection required, no data leaving your device. This is a world first for Locai Labs, and we genuinely believe it's the start of something big.

What's new

If you're a Member or Founding Member of the GB1 community, you can now download our Jupiter-G AI models straight to your iPhone, iPad, or Android device through the GB1 app. Once downloaded, you can chat with these models entirely on-device. No Wi-Fi. No cellular. No cloud round-trip.

Why this matters

Running AI locally means three things that we think really matter:

• Total privacy. Your conversations never leave your device. Perfect for anything confidential — work documents, personal questions, sensitive ideas you're still thinking through.
• It works anywhere. On a plane, on the Tube, out in the countryside, in a basement office with terrible signal — GB1 still works. No data network needed.
• A lighter footprint. No cloud data centre power or water consumption, and none of your mobile data either.

You'll be genuinely surprised how capable these small models are.

Cloud is still here when you want it

Nothing about our cloud experience changes. GB1's cloud models still run on UK GPUs powered by 100% renewable energy, and we never train on your chats. You can switch between local and cloud in the app whenever you want — pick whichever fits the moment.

A note on the current limitations: local mode is missing some of the tools the cloud version has access to. We're shipping those shortly. But even now, local models shine when you're offline or asking about something you'd rather keep entirely on your device.

The bigger picture

So why ship local models? Because we believe the future of AI is local.

We believe the future is one where people own their own AI — running on their own hardware, completely private, with unlimited usage, and with a much smaller footprint on the planet.

Right now, the big AI labs are subsidising token pricing to keep things affordable, but that isn't sustainable forever. The most genuinely sustainable and affordable path to AI for everyone is running it on the computers we're already carrying in our pockets and have sitting on our desks at home.

Phones and tablets are limited in what they can hold today, but they're getting more powerful every day — and so are small language models like Jupiter-G. We're also building models that run beautifully on laptops and workstations, so the experience scales with whatever hardware you have. Our new pre-trained Mercury models are starting small and working their way up, which means they'll run on phones and tablets from day one.

Once local models can comfortably handle the 90% of things people use AI for day-to-day, the shift to local AI really starts to take off. We don't think that's far off at all.

How to try it

It takes about a minute:

1. Update the GB1 app on iOS or Android to the latest version.
2. Open Settings.
3. Download a Jupiter-G model.

That's it. You're now running a frontier-style AI assistant entirely on your device.

We want to hear from you

If you've got thoughts, feedback, or things you'd like to see next, hit Send Feedback in Settings, or drop us a note in our Discord. We read every message.

A huge thank you to everyone in the GB1 community for your support, and a special shout-out to our Founding Members who tested this in beta and shaped so much of what shipped today. This release wouldn't be what it is without you.

Welcome to the local AI era.
