Key facts

  • Typical cost: $2,150, with the middle half of posts between $300 and $8,800.
  • That is 14% below the $2,500 median across all AI builds we track.

  • Fixed-price median $290; hourly estimate median $7,200.
  • Hourly rates mostly run from $25 to $45 an hour.
  • Most requested skills: Python, Artificial Intelligence and Machine Learning.

What the build includes

Search over internal documents lets staff ask questions in plain language and get answers from company files with sources, using retrieval-augmented generation (RAG) rather than training a model.

A typical scope

  • Ingestion from drives, wikis and databases
  • Text splitting and embedding
  • A vector store and retrieval logic
  • A chat or search interface with citations
  • Access control so people only see what they should

What drives the cost

Work expected to take under a month has a median of $260, against $24,000 for over six months. Part of that gap is built in, because hourly estimates are calculated from expected length. Fixed-price posts state a median of $290, while hourly posts work out at $7,200 on our estimate: 25 times as much. One likely reason is that fixed budgets tend to cover a small first step, while hourly posts describe sustained work.
