Freelance AI developer rates, explained plainly
Why two freelance AI developer quotes for the same job can differ by a lot, which pricing model suits your project, and how I price work.
How freelance AI developer pricing works
Rates for a freelance AI developer vary widely by country, seniority and platform, so a single number means little on its own. What you really want to compare is the total cost to get the result, including fixes and delays.
A cheaper hourly rate that needs twice the hours, or a rebuild six months later, is not cheaper. For AI developer work in particular, messy documents need clean-up before an AI can use them. Below are the pricing models and the factors that move the price.
Hourly, fixed or retainer
- Hourly — flexible for unclear work, but the total is open-ended. Ask for a weekly cap.
- Fixed price — best when the scope can be written down. You know the full cost upfront.
- Monthly retainer — a set amount of time or output each month for ongoing work.
- What moves the price — seniority, how custom the work is, integrations, deadlines and how clear the brief is.
- Data readiness — messy documents need clean-up before an AI can use them.
- Accuracy bar — customer-facing answers need more testing than internal tools.
- Running costs — model usage fees continue after the build is paid for.
- How I price — fixed price for defined AI developer projects and a retainer for ongoing work. The discovery call is free and the quote comes in writing.
What I take on as your AI developer
- LLM features — chat, search and summaries built into your product.
- AI agents — task agents that call your tools and APIs.
- RAG systems — answers grounded in your own documents.
- Automation — repetitive back-office work handed to AI with checks.
- Evaluation — tests that show whether the AI is getting answers right.
- Cost control — model choice and caching so bills stay sane.
