Responsibilities
What an AI developer usually handles
The day-to-day work, and what to ask before you agree an engagement.
A typical week
- Connect a language model to your data through an API, with access limited to what the task needs
- Write and test prompts against real examples, including cases where the answer should be “I don’t know”
- Log outputs so errors can be reviewed and corrected
Questions to ask before you commit
- How will you stop the model inventing answers?
- Where will our data be sent and stored?
- How would you measure whether the assistant is good enough to use?
Evaluation
How to evaluate an AI developer
One representative task, the output to expect and how to judge it. Availability, experience and working arrangements are confirmed before an engagement begins.
The task
Build a small assistant that answers ten of your real customer questions from a supplied document, and flags any question it cannot answer from that document.
What you should receive
- Working code in your repository
- A test sheet showing each question, the answer and whether it was correct
- A note on cost per request and known failure cases
How to judge the work
- Test retrieval, uncertainty, access control, usage limits and reproducibility; a fluent demo alone is insufficient.
- Review representative correct, ambiguous and out-of-scope cases. Inspect human approval boundaries, operator notes and recurring dependencies before a production commitment.
Getting started
The brief and access an AI developer needs
A clear brief and the right access let the work start without delays.
What to include in the brief
- The task the AI should handle, with ten real examples
- Where the source data lives and who approves its use
- What the system must never do, such as give prices or medical advice
- How a correct answer will be judged
Tools and access
- API keys for the chosen model provider, held in your account
- Read access to the documents or database involved
- A repository and staging environment
Access is granted by your team and removed at handover.
Handover
What a handover should include
Whether the engagement ends or changes, your team should be able to continue the work.
Handover from an AI developer
- Code and prompts in your repository
- A test set with expected answers
- A list of known failure cases and limits
- Notes on cost per request and how to change the model
Free role and project review
Start with a clear scope and a practical next step.
Tell us what you want to improve and share the relevant website or project details. We will review the starting point, recommend a suitable scope and provide a custom quote.
The initial review is free. Delivery, third-party charges and ongoing support are quoted separately.
How is a dedicated AI developer priced?
A dedicated AI developer is usually quoted as monthly capacity, based on the hours, skills and scope you need. You receive a custom quote within 2 working days of reviewing your brief.
How soon can work start?
After the brief, access and a first evaluation task are agreed. The proposal confirms the start date once availability and experience have been confirmed for your requirement.
Which AI models can the developer work with?
Commonly OpenAI, Anthropic and Google models, plus open-source options. The choice depends on your data, cost and privacy needs.
Who owns the prompts and code?
You do. Everything is delivered to your repository and accounts.
How is accuracy checked before launch?
Against a test set of real questions with expected answers, reviewed by your team.
