OpenAI Migration in St Davids
Moving between models or providers for St Davids organisations, where the code change is the easy part. Prompts have been tuned against a specific model's behaviour, frequently by trial and error over months — so a migration is a re-evaluation exercise, and without a way to measure quality you cannot tell whether you improved or quietly regressed.
Why this comes up
The problem
The model was swapped, everything still runs, and nobody can say whether the answers got better or worse.
What you get
What we deliver
- An evaluation set assembled before the migration, from real cases
- Old and new compared on the same inputs rather than judged by impression
- Prompts adapted rather than transplanted, since models respond differently
- Structured output and tool calling verified, as formats and behaviour differ
- Cost and latency compared on actual traffic, not on headline pricing
- A staged rollout with the option to revert on measured quality

OpenAI Migration in St Davids — common questions
- Why is the evaluation set the first task?
- Because it is the only way to know what happened. Without it, migration is judged by trying a few examples, which reliably favours whichever model handles the cases someone thought to test — and regressions on everything else go unnoticed for months.
- Can prompts be moved across unchanged?
- They will work, and rarely as well. Prompts accumulate phrasing that compensates for one model's tendencies, and carrying that to another model brings the workarounds without the problem they solved. Adapting deliberately is part of the migration.
- What is easy to overlook?
- Structured output and tool use. Applications parsing a specific response shape or relying on particular function-calling behaviour break in ways that pass casual testing, because most requests still succeed and a minority now fail differently.
- Should we move everything at once?
- No. Route a portion of traffic and compare on live cases before completing the switch, keeping the option to revert. A staged migration turns a difficult judgement into an observation, at the cost of running both for a period.
- Do you work with businesses across Pembrokeshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including St Davids and the surrounding Pembrokeshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of St Davids businesses do you usually work with?
- Simple booking and payment systems for very small hospitality and tourism operators on the Pembrokeshire coast. Beyond that we work across Tourism & Heritage, Hospitality, Agriculture, Marine and Retail.
- Do you cover the areas around St Davids?
- Yes — we work throughout Wales, including Swansea, Cardiff. St Davids is an urban area of roughly 1,600+, and we take on work across the wider Pembrokeshire region rather than the city boundary alone.
