Our base models
Frontier Performance.

The benefits of
owning your AI.
Cost effectiveness improves as the model learns.
You still pay for inference but using your own model. As it learns it gets more useful and more valuable.
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 stays 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.
