From planning and writing to learning and research, GB1 helps you get things done while putting you and the planet first — not big tech. Designed, trained and hosted entirely in the UK, GB1 delivers powerful frontier AI with privacy, sustainability and independence at its core.
Why choose GB1?
• For your eyes only.
Your conversations are yours alone. We never use them to train our models or profit from your data. GB1 uses end-to-end encryption, UK data residency and full GDPR compliance to keep your information protected.
• It’s not easy being green. Oh wait, it is.
GB1 runs on UK GPUs powered by 100% renewable energy. Our models are designed to be lean and efficient, using less compute and producing fewer emissions than comparable AI systems. Powerful AI shouldn’t cost the planet.
• World class performance? Completed it mate.
Our model Locai L1 surpasses leading foundational models on key benchmarks thanks to our proprietary innovation, Forget-Me-Not™, delivering exceptional conversational ability while using significantly less computing power.
• Independent
GB1 is built by Locai Labs, an independent AI company based in London. No big tech overlords. We're the Rebel Alliance taking on the Empire, independent, mission-driven, and answering only to our users. The force is strong with this one.
• Community driven
GB1 is shaped with input from its users. Feedback from the community directly influences new features, improvements and the future direction of the platform.
• It's British!
GB1 is developed and hosted entirely in the UK, meaning your data never leaves British legal jurisdiction. It is protected by GDPR and the UK Data Protection Act. All training data is licensed, open-source or synthetically generated.
