OneAdvanced launches private LLM for healthcare businesses
Software provider OneAdvanced has announced the launch of a large language model (LLM) for healthcare businesses, which delivers AI for role, organisation, and sector-specific work.
The firm says that its secure OneAdvanced AI service is designed to prevent staff from using unapproved generative AI solutions which could put sensitive healthcare data at risk.
Amanda Grant, chief product officer at OneAdvanced, said: “Business leaders across the world are grappling with how to use AI tools to improve their organisations, speed up processes and unlock data.
“Relying on tools that learn from the information uploaded is too risky. They need confidence that their data remains safe.
“We believe this innovation will fundamentally reshape how UK businesses safely and effectively integrate AI into their daily operations creating those highly sought after productivity gains.”
OneAdvanced AI operates as a private, closed, and fully encrypted service, with embedded sector-specific intelligence and automation.
Customers can create private team or organisation spaces for sharing and collaborating around the use of AI specific to them, their team or the wider business.
Mastercall Healthcare, a social enterprise organisation providing ‘out of hospital’ healthcare treatments is one of the first customers to experience OneAdvanced AI.
Jonathan Ritchie, director of digital innovation at Mastercall Healthcare, said: “This approach enables us to leverage AI’s capabilities while maintaining strict control over our sensitive data.
“With OneAdvanced implementing private AI solutions, we not only enhance our security posture but gain the ability to customise our AI environment, driving innovation without compromising on compliance.
“OneAdvanced private AI instils confidence throughout the organisation, allowing the Mastercall team to explore AI application use without compromising the integrity and privacy of our data.”
The solution includes retrieval-augmented generation, AI assistants and agentic AI.
Simon Walsh, chief executive at OneAdvanced said: “By coupling innovation with robust security standards, we can drive economic growth while protecting sensitive data.
“OneAdvanced AI represents a crucial step forward in ensuring that organisations can seize these opportunities without risk.”
OneAdvanced, previously known as Advanced, confirmed in November 2024 that it was removing the Carenotes electronic patient record (EPR) and the CareDirector solution for social care case management from its product portfolio.
In March 2025, the Information Commissioner’s Office (ICO) announced that it had reduced a fine imposed on OneAdvanced to £3.07 million for security failings that put the personal information of almost 80,000 people at risk.
The ICO had previously issued a provisional notice of intent to fine the firm £6.09m following a ransomware incident in August 2022 in which hackers accessed systems belonging to OneAdvanced’s health and care subsidiary.
Meanwhile, in January 2025, prime minister Sir Keir Starmer unveiled details of the government’s AI Opportunities Action Plan, which he said would “make our country an AI superpower”.
It includes recommendations for the UK to create a national data library to gather data held by the public sector, including anonymised health data, to support AI research and innovation.
