GB1: The AI from the UK

GB1 keeps conversations on British soil and operates under UK law. The company says chats are end-to-end encrypted and that it won't use them to train its models or profit from the data. That's the feature most people are here for, since it's the one thing mainstream assistants can't easily promise. It's a big deal for regulated work. If your work involves client details or personal records, this is the part that matters.

The team built a technique it calls Forget-Me-Not that keeps model quality high while cutting the computing power needed to run it. On GB1's own benchmarks, its models outrank several bigger names on instruction following, human preference, and Celtic languages, which is a bold claim for a small British outfit competing with the giants. The upside for you is faster responses and a smaller energy bill behind each question. Just note the benchmark claims come straight from the vendor.

Every request runs on renewable power, and the models are designed to be lean so they use less compute than larger systems. The company frames this as an answer to the emissions problem that follows big AI workloads. It won't change how the assistant feels to use, but it's a real differentiator if you factor environmental cost into your tool choices. Green AI, in practice.

The core experience is a familiar chat window. You type, get a reply, and keep the thread going across turns. Paid tiers expand both messaging limits and file upload size, so you can hand it a document and ask questions about the contents. Nothing exotic, which is the point. It works the way you'd expect from a modern assistant.

Instead of a long menu of tiers, GB1 leans on a single paid plan, the Founding Member, at £8.33 per month billed annually. It brings heavily expanded messaging, larger file uploads, early access to new features, and perks like a badge and a name trained into its Locai L1 model. So what do you actually get for that? More headroom and a bit of founder bragging rights.

Beyond the chat assistant, the company sells Juno 1, an on-premises AI station, and Minerva, a platform for training domain-specific models. These are aimed at organizations that want their own AI running on their own hardware rather than renting someone else's cloud. They sit outside the consumer app, but they show where the company is heading with the broader product line.
