RAG Cost Model for Pharma Trial Recruitment in 2026

Frequently Asked Questions

01.What does a production RAG system for trial recruitment cost?

A pilot covering one to three protocols typically ranges from 90,000 to 180,000 dollars for build plus the first three months of infrastructure, based on market-sourced component pricing across embedding, vector storage, inference, and integration work. A multi-protocol production deployment with SLA-tier inference and EHR integration typically ranges from 220,000 to 480,000 dollars in year one, market research range, since no audited per-project figure is publicly available for this vertical.

02.Why does inference latency matter so much for trial-matching RAG?

Trial coordinators query the system during live patient encounters, so a slow answer either gets ignored or forces a follow-up call after the visit ends. Targeting top-quartile latency by HELM's denoised inference runtime methodology keeps answer time inside the coordinator's screening window, which is the difference between the tool getting used and getting abandoned after the pilot.

03.Can a site start with an MVP trial-matching assistant before full production build?

Yes. A single-protocol pilot on a smaller open-weight model and a managed vector store can validate retrieval quality and coordinator adoption before committing to the multi-protocol infrastructure and SLA-tier inference spend, and most sites should run this pilot phase before scoping the full budget.
