OpenAI Fine-Tuning in London
Fine-tuning for London organisations, with the distinction that saves the most wasted effort: it teaches a model how to behave, not what to know. Fine-tuning to inject company knowledge is the commonest failed project in this space — retrieval does that job better, cheaper and with the ability to update when the facts change.
Why this comes up
The problem
The plan is to fine-tune the model on the company handbook so it can answer questions about internal policy.
What you get
What we deliver
- The objective tested against whether fine-tuning is the right mechanism at all
- Training examples built to demonstrate the behaviour, format or tone required
- Data quality prioritised over quantity, since a few hundred good examples beat thousands of poor ones
- A held-out evaluation set kept separate from anything used in training
- Base model comparison run first, to establish what tuning actually gained
- Retraining planned, because a tuned model does not follow the base model forward

Working in London
London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.

OpenAI Fine-Tuning in London — common questions
- Why does fine-tuning not teach facts well?
- Because it adjusts behaviour rather than storing retrievable knowledge. A tuned model will produce output shaped like your documents while inventing details, and it cannot be updated when a policy changes without training again — which retrieval handles trivially.
- What is it genuinely good for?
- Consistent format, tone and task behaviour. Producing output in a specific structure, adopting a house style, or reliably performing a narrow classification are all cases where a tuned model outperforms prompting and costs less per request.
- How many examples do we need?
- Fewer than expected, and they must be good. A few hundred carefully constructed examples demonstrating exactly the behaviour you want typically beat thousands scraped together, because inconsistencies in the training data are learned along with everything else.
- What happens when a new base model arrives?
- Your tuned model stays where it is. The improvements in newer base models do not reach it, so the comparison worth rerunning periodically is your tuned model against a well-prompted current one — which sometimes ends the need for tuning entirely.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
