Welsh Government partners with Cosine to advance Welsh language AI

September 2026 | AI & Automation, Culture and language, Featured

A new partnership with sovereign AI company Cosine to help improve how AI works in Welsh has been announced.

The Welsh Government will provide data, resources and expertise to help improve how Cosine’s Lumen AI model understands and processes Welsh.

Ensuring that the Welsh-language thrives in the digital age is a Welsh Government aim.  They hope that improving the technology will help more people to use Welsh in everyday life.

It also supports the government’s work to ensure new technologies recognise, understand and support bilingual use, reflecting how multilingual communities all around the world use AI every day.

Chief Executive Officer of Cosine, Alistair Pullen, said:

“Welsh is an essential part of the UK’s linguistic landscape. This work with the Welsh Government helps us build Lumen on a stronger foundation, with better representation of the languages and public context that matter across the UK.”
