A custom AI agent typically costs about $3,850. Half of the 2,831 priced job posts we tracked fall between $600 and $10,000, and one in ten reaches $24,500 or more.

## Key facts

- Typical cost: $3,850, with the middle half of posts between $600 and $10,000.
- That is 54% above the $2,500 median across all AI builds we track.
- Work expected to take under a month has a median of $600, against $14,100 for over six months.
- Fixed-price median $300; hourly estimate median $6,800.
- Hourly rates mostly run from $20 to $42 an hour.
- Most requested skills: Python, Artificial Intelligence and AI Agent Development.

## What it includes

A custom AI agent is software that uses a language model to plan steps and act across tools and data, rather than answering a single prompt, so it can complete multi-step work with limited supervision.

- The agent's instructions and decision logic
- Tools it can call, such as APIs, databases and search
- Memory or retrieval over your data
- Guardrails and approval steps for risky actions
- Evaluation runs and logging of what the agent did

## What drives the cost

Work expected to take under a month has a median of $600, against $14,100 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 $300, while hourly posts work out at $6,800 on our estimate: 23 times as much. One likely reason is that fixed budgets tend to cover a small first step, while hourly posts describe sustained work.
