01
Use open foundations
Adapt proven models rather than spend time and money reproducing them.
About
A small company with a defined remit.
Talwen adapts open language models for UK public and regulated work, and researches British speech and voice.
Our work
What we are building.
We start with capable open foundation models. We fine-tune and evaluate them against UK legislation, public guidance, institutional language, professional standards and everyday British usage.
Deployment matters as much as model behaviour. Work may require UK data residency, controlled retention, auditable changes and clear human responsibility.
Talwen is early and small by design. We work with organisations, researchers, technical specialists and independent contributors who know or care deeply about the domain being modelled.
Working principles
How we work.
02
Keep data under agreed control
Specify where data is processed, what is retained, who can access it and which law applies.
03
Test the actual task
Evaluate against the decisions, documents and language the model will meet in use.
04
Publish limits
Record known failures, unsuitable uses and changes that affect behaviour.
Language and place
The name
Talwen is a coined word built on old Welsh roots: tal - "high," and of "radiant brow" - and -wen (from gwen), meaning "fair, bright, blessed." Folded into it are two things we care about: Taliesin, the legendary British bard whose name means "radiant brow," remembered as the voice of these islands; and awen, the Welsh word for the flowing spirit of inspiration.
We chose it because it says, quietly, what we are trying to build - a bright, thoroughly British voice, rooted in the best of who we are and reaching for something higher.
