What moves the price
Integrations and data cleanup usually cost more than the model work. A single-source Q&A assistant is the cheapest build; agents that write to your systems, need approvals and audit logs, or run on private models cost the most.
Running costs
Budget separately for model usage (per-token fees or GPU hosting), a vector database if used, and monitoring. Ask the agency for a per-request cost estimate from their test runs.
