Direct answer
An AI MVP can range from a focused diagnostic and prototype to a larger product build. The cost depends on workflow complexity, data readiness, integrations, quality checks, UX, and how much senior technical leadership is needed.
What drives cost
The main drivers are data availability, integrations, review loops, permissions, reliability needs, UI complexity, and whether the team needs CTO-level architecture before implementation.
A safer budgeting sequence
Start with a paid diagnostic or architecture sprint, then decide whether the next step is prototype, MVP build, vendor handoff, or internal hiring. That avoids pricing a vague idea as if it were a finished spec.
