AI Agent Development Cost: What You Actually Pay For
What AI agent development costs in 2026 — by agent type, from $6k support bots to $150k+ autonomous workflows — and the four line items that drive it.
We build agents with the harness, evals and guardrails that keep them reliable after launch — on the Claude Agent SDK, managed agents or your own stack.
One process, its volume, its systems, its cost of error. Fixed price in 48 hours.
Tools, harness, permissions and the eval set from your real data.
Agent proposes, your team approves, for one to two weeks.
Live on a slice of traffic, then all of it as the numbers hold.
| Tier | Scope | Timeline | Price |
|---|---|---|---|
| Retrieval assistant | Answers from your docs and helpdesk | 2–4 weeks | $6k – $18k |
| Workflow agent | Triage, drafting, CRM updates | 4–8 weeks | $20k – $55k |
| Multi-tool agent | 5–15 tools, approvals, evals | 8–14 weeks | $55k – $120k |
Every project starts with a written scope and a fixed price, delivered within 48 hours of your brief.
The current frontier model that passes your eval set at the lowest cost, with cheaper models routed in for simple steps. The eval suite makes switching safe.
Yes — repository in your organisation from the first commit, IP assigned on payment.
Irreversible actions sit behind approval gates until the eval pass rate earns autonomy, and every run is traced so mistakes are visible and fixable.

What an AI agent actually is, how it differs from a chatbot and from automation, what it can and cannot do in 2026, and what one costs — no jargon.
The seven reasons AI agents that pass the demo fail in production — context, tools, evals, permissions, latency, cost, ownership — and the fix for each.
