Generative Artificial Intelligence Electronic Performance Support System

The buyer seeks a vendor to provide a generative artificial intelligence electronic performance support system. The required scope demands strict retrieval-augmented generation grounding that confines AI generation exclusively to approved organizational data, alongside an explainable AI framework. The system must utilize a hybrid retrieval architecture combining dense vector semantic search and sparse keyword search in parallel. Additional scope requirements include Zero Trust architecture, offsite data encryption, dynamic masking of personally identifiable information and protected health information, strict role-based access control, deterministic defenses against prompt injection attacks, and runtime memory optimization guardrails to prevent thrashing. Only onshore US organizations are eligible to submit proposals for this offsite work. The buyer is looking for proposals to establish the budget. Vendors must submit all questions no later than August 28, 2026. The provided text contains no further details regarding evaluation criteria.
