AI Agent Development Cost.

Typical market ranges: a scoped proof of concept runs $15,000–$50,000, a production single-purpose agent $50,000–$150,000, and a multi-agent or enterprise system $150,000–$400,000+. The final number depends on tool integrations, evaluation depth, accuracy targets and compliance requirements. A fixed quote requires a short discovery phase.

A focused proof of concept — one workflow, one or two integrations, a basic evaluation set — typically costs $15,000–$50,000 and takes 2–4 weeks. The POC should answer whether the agent can hit your accuracy target on real data, not just produce an impressive demo.

Monthly run costs combine model tokens, vector storage, orchestration hosting and observability. A support agent handling a few thousand conversations a month on a mid-tier model usually costs a few hundred dollars; research agents with long multi-step loops can cost several thousand. We model token consumption per task before build so the bill is predictable.

Fixed-price works best for discovery, POCs and well-scoped production builds — you know the number before work starts. A monthly retainer fits the run phase: eval maintenance, model upgrades, prompt tuning and new tool integrations. Most engagements are a fixed-price build followed by a small retainer.

The biggest cost drivers are write access to production systems (payments, refunds, record changes), the number and quality of APIs the agent must call, accuracy and latency targets, human-in-the-loop requirements, and compliance needs such as SOC 2 controls or HIPAA safeguards. Legacy systems without usable APIs add the most.

A narrow first scope, read-only tools before write tools, existing authentication you can reuse, a smaller model that still passes your eval suite, and managed infrastructure instead of self-hosted clusters. Routing simple steps to cheaper models and caching repeated queries also cuts monthly run costs significantly.

Yes. Every engagement starts with a 1–3 week discovery phase that maps the workflow, lists integrations and defines success metrics. You then receive a written, fixed-price scope with milestones and acceptance criteria — no open-ended hourly billing.
