Argyll Data Development and SambaNova are teaming up on a UK sovereign AI cloud.

The AI cloud will use SambaNova’s AI infrastructure, including the latter’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 SN40L chip was launched in September 2023 and is capable of running models with up to five trillion parameters. Manufactured by TSMC, SN40L supports 256k+ sequence length possible on a single SN40L node. SambaNova separately offers an AI inference cloud based on the chip dubbed SambaNova Cloud.

The deployment will be housed in the Killellan AI Growth Zone, a 184-acre digital campus in Scotland on the Cowal Peninsula. 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.

“Together with SambaNova and our strategic partners, we’re building a sovereign AI infrastructure powered by renewable energy, demonstrating that sustainability and scale can go hand in hand. Our goal isn’t just to make AI greener, but to make it competitive, compliant and cost-effective,” said Peter Griffiths, executive chairman at Argyll. “This project gives UK enterprises the ability to innovate responsibly, securely and within our own borders, in full alignment with national AI ambitions.”

“Argyll is a blueprint for scaling AI responsibly. By pairing renewable power with high-performance, energy-efficient computing, it shows what sustainable AI infrastructure can achieve,” said Rodrigo Liang, CEO and co-founder of SambaNova. “With SambaNova’s chips-to-model platform, we’re enabling large-model inference with maximum performance per watt, while helping enterprises and governments maintain full control over their data and energy footprint.”

Argyll was founded in 2023 and is developing the 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.

Waste heat from the data centers will be used to support vertical farming, aquaculture, and local district heating.

Scotland has not traditionally been a data center hotspot, though since the AI Growth Zone initiative was announced, several of its regions have confirmed they have submitted bids, including North Ayrshire, Dumfries and Galloway, and the city of Glasgow.
