Overview

Nexus AI is Devix's flagship intelligence layer — a secure, model-agnostic platform that connects LLMs to an organization's documents, databases, and tools. Every answer is grounded, cited, and auditable, with guardrails, evaluation pipelines, and human-in-the-loop review baked in.

Highlights
  • Grounded answers with inline citations & confidence
  • Model-agnostic routing across Claude, GPT, and local models
  • Vector + hybrid retrieval over private corpora
  • Eval harness with automated regression scoring

Challenges

Hallucination risk

Enterprise stakeholders required answers that could be trusted, traced, and defended in regulated contexts.

Knowledge freshness

Source systems change constantly; stale embeddings produce wrong answers with high confidence.

Solutions

Grounded RAG pipeline

Hybrid retrieval with re-ranking plus citation enforcement — answers without sources are blocked at generation time.

Incremental indexing

Change-data-capture streams keep the vector store continuously fresh within seconds of source updates.
