How much does it cost to build an AI app in 2026?
Short answer
A focused AI feature added to an existing product runs $10k–$40k and takes 2–6 weeks. A full AI product — custom models, retrieval, evaluation, production infrastructure — runs $30k–$120k over 8–16 weeks. The variable that moves the number most is data readiness, not model choice.
Pricing conversations usually stall because 'AI app' covers two very different projects. Adding an assistant to software you already run is an integration: the product exists, the users exist, and the work is wiring a model into real data safely. That is the $10k–$40k band.
Building an AI product from nothing is a different exercise. You are designing the interface, the data pipeline, the evaluation process and the cost model at once. Budget $30k–$120k and expect the schedule to be driven by how clean your data is.
The cost nobody quotes for is evaluation. If you cannot measure whether the AI is getting better or worse, you cannot ship changes with confidence, and the thing quietly degrades. Any credible quote includes an evaluation set.
Be suspicious of anything dramatically cheaper. What usually got cut is exactly this: evaluation, guardrails, and security review.
