OneAdvanced has launched a triage AI built for the NHS that it claims matches Claude's performance while keeping all patient data on UK soil.
The Birmingham-based SaaS company, whose software already reaches more than 40 million NHS patients, calls the system Care Navigator and markets it as the UK's first "sovereign" large language model for healthcare triage. The sovereignty angle is the core differentiator: patient data stays on domestic infrastructure rather than flowing to servers run by American cloud providers. OneAdvanced says the model was trained at a fraction of the cost of licensing a frontier model from a US lab.
The NHS has been swamped with AI proposals, but most rely on infrastructure that would route sensitive health records outside the UK, a live tension under data protection rules. A domestic model that performs as claimed removes that blocker and could push NHS trusts that have been stalling to act.
"Rivals Claude at a fraction of the cost" is doing a lot of work as a marketing line. Performance comparisons in healthcare AI tend to look softer once independent clinicians get hold of the benchmarks.
