GB1: The AI from the UK

About GB1: The AI from the UK

GB1 is a UK-hosted AI assistant that prioritises user privacy and sustainability. It runs on 100% renewable UK energy, keeps data in the UK, and does not train on user chats.

Review

GB1 positions itself as an alternative to large, externally hosted AI services by combining local data residency, privacy-by-default policies, and environmentally conscious infrastructure. The product is available on web and mobile, and the team is opening API access on a rolling invite basis while inviting user input on the roadmap.

Key Features

• Private by default - chats are not used for model training and user data remains in the UK.
• 100% renewable energy - message processing runs on UK GPUs powered by renewables.
• Powered by Locai L1 Large - a British foundational model post-trained on Qwen-3 with the Forget-Me-Not framework, emphasising improved reasoning, more neutral alignment, and support for languages like Welsh, Irish and Scottish.
• Spaces for organising projects and cross-device chat on web and mobile.
• Community-driven roadmap and early-access API invites for developers and testers.

Pricing and Value

The listing indicates an interactive free offering for initial use, with the API in early access and invites being issued on a rolling basis. The value proposition centres on privacy guarantees, UK data residency, and lower carbon footprint, which may be especially relevant for individuals and organisations that prioritise legal jurisdiction and eco-conscious hosting.

Pros

• Strong privacy posture: chats are not used to train models and data is kept in-country.
• Operates on renewable UK energy, reducing the carbon impact of usage.
• Local foundational model with attention to reasoning and under-represented languages.
• Community engagement through roadmap voting and early-access opportunities.
• Convenient web and mobile apps plus project-oriented Spaces for organisation.

Cons

• As a small startup offering, some features and integrations are still in early access and may be limited compared with larger providers.
• API access is invite-only at launch, which may slow adoption for developers and teams wanting immediate integration.
• The model's reduced content filtering in favour of more neutral alignment could result in different moderation behaviour than mainstream offerings.

GB1 is best suited for UK-based users and organisations that need clear data residency, privacy-first defaults, and lower-emission hosting. It also appeals to people who want to help shape a product roadmap and test early features; those needing mature enterprise integrations or broad third-party ecosystem support may find it more limited for now.
