Custom LLM Development in Newport
Custom language model work for Newport organisations whose requirements genuinely exceed what a general model plus good prompting can do. The first thing worth saying plainly is that this is rarely the answer — most problems described as needing a custom model are solved by retrieval and careful prompting at a fraction of the cost.
Why this comes up
The problem
A general model does not perform well enough on a specialist task, and the assumed solution is training a model. Nobody has yet tested whether better retrieval and clearer instructions would close the gap.
What you get
What we deliver
- An honest assessment of whether a custom model is warranted at all
- A baseline measured with prompting and retrieval, so any gain is attributable
- Data assembled and cleaned, which is the majority of the real work
- Fine-tuning or adapter training where the evidence supports it
- Evaluation against the baseline, not against a subjective impression
- A deployment and update plan, since a model is a thing you maintain

Custom LLM Development in Newport — common questions
- Do we need our own model?
- Usually not. Retrieval over your documents and well-specified prompts handle most domain-specific tasks, and both are cheaper to build and far cheaper to change. Custom training earns its place for unusual formats, specialist vocabulary or strict on-premise constraints.
- How much data would we need?
- For fine-tuning a task, often hundreds to a few thousand good examples rather than the enormous volumes people imagine. Quality and consistency matter far more than quantity — inconsistent labelling teaches the model to be inconsistent.
- What does it cost to keep running?
- More than calling an API, and the difference is ongoing rather than one-off — hosting, monitoring, and re-training as the world moves. That maintenance cost is what makes an honest baseline comparison worth doing before committing.
- How do we know it is actually better?
- By measuring against the prompting baseline on a held-out evaluation set. Without that comparison you cannot tell whether the custom model improved anything or simply cost more, and the question tends to arrive at budget time.
- Do you work with businesses across Newport?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Newport and the surrounding Newport area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Newport businesses do you usually work with?
