The Locai Platform
We build AI that you own and control.
Your own bespoke LLM.
A foundation model post-trained on your data and continuously retrained as your business develops. Your data, your weights, your IP.
Chat. Coder. Agent.
One deployment-ready application to enable multiple workflows including chat, coding and agentic capability.
Secure deployment.
Deployed securely on either your sovereign private cloud, air-gapped, or our dedicated Locai Labs managed cloud. ISO 27001 compliant.
Continual learning.
Data collected through the applications feeds scheduled retraining runs powered by our proprietary continual-learning framework, so the model compounds in value the more your team uses it.

Locai Coder
Your coding model.Your hardware.
A frontier-grade coding model that ships as a workstation, a rack, or in your cloud. Trained on your codebase, served to your whole team, with nothing ever leaving your environment.
Customer Case Study, First Light Fusion
"We've been impressed by the quality and speed of the work delivered by Locai Labs."
Mark Thomas
CEO, First Light Fusion
First Light Fusion is an Oxford University spinout developing inertial confinement fusion energy. Locai Labs deployed FLF Coder, a domain-specific coding model, air-gapped and trained on their scientific and engineering workflows, to accelerate their fusion programme.
Our base models
Frontier Performance.
Every Locai model starts at frontier-grade capability. Benchmarked, openly published, and engineered to retain the base model's strengths when we adapt it to your domain with your data.

Locai-L1-Large compared against the leading frontier models per benchmark. Sources: Arena Hard v2 (GPT-4.1 judge), IFEval and BritXNLI.
Jupiter-N
Oursvs. Nemotron base
All values in %. Reasoning on/off configurations match those reported in the Jupiter-N technical report. Welsh benchmarks evaluated reasoning-off.
Jupiter-G
Oursvs. Gemma-4 base
All values in %. Same Locai post-training recipe (Forget-Me-Not™ replay + curated SFT) applied to a different open base. General knowledge held within ~1.4 pts of base while gains stack on instruction following, safety and code.
The benefits of
owning your AI.
Pay for the infrastructure once, not per prompt.
Fixed-cost deployment with no per-token bills. Run unlimited inference inside your environment, and the model gets sharper, and more valuable, the more your team uses it.
Your data, your IP.
The weights, the training data, and everything the model learns stays yours. You retain full ownership of the IP.
Your model and your data stay put.
The model runs inside your sovereign perimeter, in the jurisdiction you choose.
Trained on your business.
Post-trained on your documents, your workflows, and your domain, so it understands your context the way no off-the-shelf general model can.
Smarter every retrain.
Your model retrained using our Forget-Me-Not™ framework. The more you use it, the more it knows about your business, creating an asset that compounds in value.
Full audit trail.
You have full access to the weights, the training data, and the post-training process. With logs and traceability.
Built using British
science and know-how.
Locai Labs is a British company headquartered in London.
