Argyll Data Development and SambaNova have launched their sovereign AI inference cloud in the UK.

The cloud platform runs on SambaNova’s AI hardware and software stack within existing UK data centers.

The two companies first announced their intention to establish a sovereign AI cloud platform in October 2025, noting at the time that it would use SambaNova’s air-cooled SN40L systems. According to the company, the SN40L uses roughly one-tenth of the power of a traditional GPU system; thus, liquid cooling is not necessary.

The deployment was said at the time to be housed in the Killellan AI Growth Zone, an 184-acre digital campus in Scotland on the Cowal Peninsula, which is being developed by Argyll. The first phase of the Growth Zone will offer 100 to 600MW of capacity and reach 2GW at full build-out. The site is described as a “green” campus, and the AI cloud will be powered by renewable energy.

Now launched, Argyll said that the platform is instead architected as a “disaggregated platform, allowing compute, storage, and networking to be deployed across multiple UK locations while operating as a single, unified inference layer” from existing UK data centers.

The data centers it uses have not been disclosed.

In addition, it is also running on SambaNova’s Reconfigurable Data Unit (RDU) architecture and uses the SambaManaged solution. The deployment operates with a density of around 10kW per rack. SambaNova launched its SN50 AI chip based on RDU architecture in February of this year. According to the company, it features a three-tier memory design that supports 10 trillion parameter models and can power “thousands of simultaneous AI sessions with consistent high performance.”

Peter Griffiths, chairman at Argyll Data Development, said: “Sovereignty in AI is not a label you can apply to a contract or a colocation agreement. It is a condition that has to be demonstrated – who is accountable, where the infrastructure sits, who controls the intelligence layer, and whether all of that aligns with the expectations of the society being served. Our platform satisfies those conditions. We are building the standard that others should be measured against.”

Jude Sheeran, managing director, EMEA at SambaNova, added: “As organizations scale AI, many are defaulting to GPU infrastructure without fully accounting for long-term cost, energy, and operational complexity. Our work with Argyll provides an alternative, enabling high-performance AI inference that is more efficient, deployable, and aligned with sovereignty requirements.”

Argyll was founded in 2023 and is developing the Killellan AI Growth Zone, plans for which were revealed in August 2025. A total investment of £15 billion ($20.03bn) is expected to be made in the campus.

Founded in 2017, SambaNova previously focused on training workloads, but pivoted in 2025 to become an AI cloud services provider. Its Suite product is touted as an on-prem or cloud-based offering that allows companies to train their own generative AI models based on popular foundation models.

The company first unveiled its SambaNova Cloud in September 2024. It provides cloud-based AI inference services using the company’s SN40L AI chip, launched in September 2023 and capable of running models with up to five trillion parameters. Earlier this year, the company raised $350 million in a Series E funding round led by Vista Equity Partners and Cambium Capital, with “strong participation” from Intel Capital.
