    We design and
    build sovereign
    foundational AI

    Locai Labs was founded on a clear mission: to build independent sovereign foundational AI. We saw an industry dominated by a handful of closed systems, prioritising profit over people and believed there had to be a better way.

    Driven by this conviction, we set out to create AI that is fundamentally different. Our approach is centred on transparency, guided by community input, and designed to serve the diverse, real-world needs of people solving real problems.

    AI impacts all of us, so it's vital that we all get the opportunity to have our say as it develops. GB1 is collaborative, community-driven, and human-first.

    Join our discord community and shape what we build next.

    Being open by design means building AI that is accessible, auditable, and created in collaboration with the world. We're committed to sharing our models, research, and methods so anyone can inspect, improve, and build upon them.

    Your data belongs to you. We believe AI should work for people, not exploit them. GB1 is built with privacy at its core, no data harvesting, no hidden tracking, and full UK data residency.

    AI doesn't have to cost the earth. We're committed to building efficient models powered by 100% renewable energy, proving that cutting-edge AI and environmental responsibility can go hand in hand.

    Built using British science and know-how

    We built GB1 using our Forget-Me-Not framework to improve and de-bias a high-performance open-source model so that it is aligned with the laws, languages and idioms of the UK.

    With GB1, we can now write our AI future in our own words, aligned with our values of sustainability, transparency, privacy, and community.

    That's what we've built, and what we now invite you to be a part of: the UK's first foundational large language model, built to protect the sovereignty of the UK, and to power the next era of British ingenuity. And we're just getting started...
