01_TECHNICAL_DECISION_MATRIX

LAYER PRIMARY_TECH STRATEGIC_LOGIC GOTCHA
Embeddings OpenAI v3 (3072d) / Voyage-2 High-rank semantic resolution. Mandatory for large corpora (1M+). Increased indexing latency vs 1024d.
Reasoning Command-R+ / Gemini 1.5 Pro Gemini for 2M context analysis. Command-R+ for native citation grounding. Long-context windows dilute attention. RAG required for precision.
Orchestration Dagster (DAG) + FastAPI Modular pipeline lifecycle. No no-code duct tape. Full audit trails/retry logic. LangChain for prototypes; code-centric DAGs for production.
Private Deployment BGE-M3 / Local VPC Self-host when residency or API cost at scale (1B+ docs) outweighs infra. Requires 16GB-24GB VRAM per GPU executor.

03_MODEL_FAMILY_INTEROPERABILITY

We architect for a composition of specialized layers, not a monolithic model call. This ensures your capital is not tied to a single provider.

  • Embeddings = Your Semantic Index
  • Reasoning Models = Your Generation Layer
  • Guardrails = Your Operational Truth

04_CONTINUED_VECTORIZATION

Our systems treat institutional data as a living semantic asset. New text is embedded once into searchable units (chunks) and stored forever.

  • Real-time Ingestion via FastAPI
  • Semantic "Fingerprinting" (Embeddings)
  • Permanent Vectorized Persistence

02_INFRASTRUCTURE_SPECIFICATIONS

Storage & IOPS

SSD RAID-10 architectures with pgvectorscale. Optimized for disk-heavy HNSW indexes reaching >1M IOPS on 64-core hardware.

Horizontal Scaling

Read replicas for similarity search fanning. Citus sharding for 10TB+ corpora spanning billion-vector tables.

Integrity Protocols

Hybrid retrieval (Vector + Keyword) + Reranking. "Zero-Context Rejection" to enforce truthfulness over generation.

SECURITY_LAYER_v2.1

DATA_ISOLATION

Architectures utilize VPC-level isolation. Dedicated indexes per environment.

NO_TRAINING

Zero-retention policy for model training. Proprietary IP stays proprietary.

RAG_GROUNDING

Specifications enforce document-only retrieval. No generative hallucinations.

VECTOR_EXIT

Full client ownership of embeddings, vector weights, and system metadata.
