Hey everyone, I’m James, CEO & co‑founder of Locai Labs, a new foundational AI company from the UK and the team behind GB1.
We love AI, but we hated how it was being built. Today it’s controlled by a handful of companies, trained on data without consent, and powered by infrastructure that isn’t sustainable. So we decided to build the AI we believe in - private, sustainable and independent.
We’re a small startup out of London trying to be the polar opposite of big tech. GB1 is private by default, we never train on your chats (even for free users), and your data never leaves the UK. GB1 runs entirely on GPUs in the UK powered by 100% renewable energy, so every message you send is processed on renewables. We’re also building in the open, with a community‑driven roadmap where you can suggest ideas and upvote what we build next.
Under the hood is our model, Locai L1 Large, the first British foundational AI model. We post‑trained it on Qwen‑3 using our Forget‑Me‑Not framework that allows the model to improve itself. We focused on stronger reasoning and instruction following, reduced censorship for more neutral alignment, and expanded support for under‑represented languages like Welsh, Irish and Scottish.
Key highlights:
• Private by default, we never train on your chats (even for free users)
• Your data never leaves the UK
• Runs on 100% renewable energy
• Powered by Locai L1 Large, the first British foundational AI model
• Stronger reasoning, more neutral alignment, and support for under‑represented languages
• Community‑driven roadmap with feature voting
This launch is just the start with lots of new updates, features and models on the way! Would love to hear your thoughts, feedback, and questions, and if you like what we’re building, an upvote means a lot!
Cheers,
James
Have been using it since the web app. Glad to see the app release. The Spaces feature is definitely cool and unique. The customisation helps to make it feel my own, esp for my phone.
The framing matters here. "Private by default" isn't a feature — it's a value statement. Most AI tools make privacy a premium. You've made it the foundation. The planet angle is quietly bold too. Curious how users respond to that — do people actually feel the difference, or does it stay invisible until the moment they need it most?
Congratulations on the launch, going to be keeping an eye on this. It's great to see a UK business taking on this and giving options in the market.
Is it just a Chat interface or do you have platform API?
Following with interest. So far it is working well and communication from the devs is timely and useful. It also shifts the tech focus from US centrism - which seems to be the flavour of the day lately, all for it.

Who hunted GB1: The AI from the UK?
GB1: The AI from the UK was hunted by James Drayson. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
