Many defence, healthcare, and financial enterprises cannot route intellectual property through public API endpoints. This paper details local embedding models, quantized weights, and high-performance hybrid vector stores operating on customer-controlled private clusters.
Key Technical Findings
On-premise hardware sizing recommendations for 70B parameter open-weights models
Vector index isolation with role-based document level security (RLS)
Deterministic audit logging for all semantic retrieval queries and citations
Hybrid dense-sparse lexical scoring to eliminate hallucinated references
The Sovereign Compute Mandate
Regulated industries face strict legal boundaries governing data residency and algorithmic processing. For organizations subject to ITAR, HIPAA, or strict banking secrecy laws, commercial LLM APIs with multi-tenant cloud serving are categorically prohibited.
True enterprise AI readiness requires sovereign on-premise or sovereign private cloud architectures where weights, vector indices, and inference runtimes remain entirely within the customer's cryptographic boundary.
Hybrid Retrieval Architecture (Dense + BM25)
Standard naive vector search retrieves chunks solely based on cosine proximity in latent space. In enterprise engineering and legal documents, this frequently fails when users search for exact serial numbers, regulation clauses, or part codes.
Our architecture fuses dense semantic embeddings with sparse BM25 lexical ranking via reciprocal rank fusion (RRF), guaranteeing high semantic comprehension without sacrificing exact lexical fidelity.
“Decoupling diagnostic telemetry from human triage workflows reduces MTTR by eliminating queue latency before root-cause analysis even begins.”
— Digital Futurus Architecture Technical Working GroupHardware Sizing & Quantized Serving
Serving modern 70B parameter models privately once required prohibitive GPU clusters. Using 4-bit and 8-bit quantization techniques (AWQ/GPTQ) running on modern tensor architectures, enterprises achieve sub-30ms token latency on standard commodity server nodes.
Zero-Trust Document Access Control
Retrieval pipelines must inherit the enterprise identity provider's access control lists (ACLs). Every indexed vector carries cryptographic access tokens matching Active Directory or Okta roles, ensuring confidential HR or executive data is never surfaced to unauthorized employees.
